# SmartChat API reference

# API reference

URL: https://docs.smartchat.marketing/en/api/

> Every call of the REST API, grouped by area, with permission, parameters, examples in curl, Python and TypeScript, and all possible errors.

The reference is generated from the register of the API. It is always the same as the real API: a call that is not here does not exist.

Each call page shows: what it does, the permission it needs, the risk, whether an `Idempotency-Key` is needed, all parameters, working examples in three languages, the answer and every error it can return.

# Permissions

URL: https://docs.smartchat.marketing/en/api/permissions/

> Every permission of a key, which level includes it, which need their own checkbox and which calls use it.

A key has a set of permissions. You choose a level when you create the key and can tick single permissions. A call with a missing permission fails with [`insufficient_scope`](https://docs.smartchat.marketing/en/errors/#insufficient_scope).

| Level | What it means | Permissions |
|---|---|---|
| Read | Read everything that is not secret. Changes nothing, with one exception: it can request a contact export, which creates a file with personal data. | 17 |
| Draft | Everything in Read, plus create and change drafts. Nothing reaches other people. | 25 |
| All | Everything except deleting and the plan. It includes the permissions with their own checkbox; in the app you can untick them. | 38 |

Permissions with "yes" in the column **Own checkbox** reach other people or reveal secrets. The level **All** includes them, but in the app each of them has its own checkbox that you can untick. The levels **Read** and **Draft** never include them.

There are no permissions for deleting. See [what keys can never do](https://docs.smartchat.marketing/en/authentication/).

Permission and effect are two different things. A permission says which calls a key may make. An effect says what a call does. `create_contact_export` needs the permission `contacts:read`, because it reads your contacts. It still creates a new file with their names, phone numbers and email addresses. That is why MCP marks the tool `export_contacts` as a write tool (`readOnlyHint` is `false`). A key with only the level **Read** can therefore start an export.

| Permission | What it allows | Read | Draft | All | Own checkbox | Used by |
|---|---|---|---|---|---|---|
| `contacts:read` | Read contacts, tags and contact export requests (phone numbers included). | yes | yes | yes | - | [get_optin_status](https://docs.smartchat.marketing/en/api/reference/account/get_optin_status/), [search_contacts](https://docs.smartchat.marketing/en/api/reference/contacts/search_contacts/), [get_contact](https://docs.smartchat.marketing/en/api/reference/contacts/get_contact/), [list_tags](https://docs.smartchat.marketing/en/api/reference/contacts/list_tags/), [create_contact_export](https://docs.smartchat.marketing/en/api/reference/contacts/create_contact_export/), [get_contact_export](https://docs.smartchat.marketing/en/api/reference/contacts/get_contact_export/) |

# OpenAPI, Postman and other files

URL: https://docs.smartchat.marketing/en/api/openapi/

> The machine-readable description of the API, the Postman collection, llms.txt and the Markdown version of every page.

| File | What it is |
|---|---|
| [openapi.json](https://docs.smartchat.marketing/openapi.json) | The OpenAPI 3.1 description of the API. This is the one source; the reference is made from the same data. |
| [openapi.yaml](https://docs.smartchat.marketing/openapi.yaml) | The same as YAML. |
| [postman-collection.json](https://docs.smartchat.marketing/postman-collection.json) | A Postman collection with one request per call. Set the variable `api_key`. |
| [llms.txt](https://docs.smartchat.marketing/llms.txt) | A list of all pages for AI assistants. |
| [llms-full.txt](https://docs.smartchat.marketing/llms-full.txt) | All pages in one file. |
| [smartchat-docs.zip](https://docs.smartchat.marketing/smartchat-docs.zip) | All pages as Markdown plus the OpenAPI files. |
| [sitemap.xml](https://docs.smartchat.marketing/sitemap.xml) | All pages. |

Every page is also available as Markdown: add `.md` to its address, or use the link at the bottom of the page.

## Use OpenAPI to make a client

Any OpenAPI 3.1 generator can make a client from `openapi.json`. Each call has an `operationId` that equals the name used in this reference. The MCP server uses the same name for most tools; where it differs (for example `save_contact` for `create_contact` and `update_contact`), the name is in `x-mcp-tool` and in the column **REST operationId** of the [tool list](https://docs.smartchat.marketing/en/mcp/tools/). Extra fields starting with `x-` describe the permission (`x-scope`), the risk (`x-risk`), the effects (`x-effects`) and the MCP tool (`x-mcp-tool`).

**Query parameters**

| Name | Type | Required | Description |
|---|---|---|---|
| `limit` | integer | no | Items per page (1 to 100, default 20). 1 to 100; default `20` |
| `cursor` | string | no | next_cursor from the previous page. Opaque; only valid with the same filters. up to 300 characters |
| `role` | string | no | Only answers with this role. one of: `rule`, `note` |
| `include_disabled` | boolean | no | True also lists switched-off answers. default `false` |

## Lists, filters and sorting

- Items per page: `limit` from 1 to 100, default 20 (MCP: default 20, maximum 50).
- Next page: send `next_cursor` of the answer as `cursor`. The cursor only works with the same filters. See [Pagination](https://docs.smartchat.marketing/en/concepts/pagination/).
- Filters: `role`, `include_disabled`.
- Sorting: default `created_at` descending; `order_by` accepts `created_at`.

## What it does

- Only reads data. It changes nothing and sends nothing.

## Request

**Query parameters**

| Name | Type | Required | Description |
|---|---|---|---|
| `limit` | integer | no | Items per page (1 to 100, default 20). 1 to 100; default `20` |
| `cursor` | string | no | next_cursor from the previous page. Opaque; only valid with the same filters. up to 300 characters |
| `status` | string | no | Only automations with this status. one of: `draft`, `active`, `paused` |
| `trigger` | string | no | Only automations with this main trigger. one of: `signup`, `keyword`, `message_received`, `message_sent`, `link_clicked`, `tag_added`, `tag_removed`, `contact_created`, `contact_updated`, `status_changed`, `note_added`, `date`, `inactivity`, `purchase`, `inbound_webhook`, `api_call` |

## Lists, filters and sorting

- Items per page: `limit` from 1 to 100, default 20 (MCP: default 20, maximum 50).
- Next page: send `next_cursor` of the answer as `cursor`. The cursor only works with the same filters. See [Pagination](https://docs.smartchat.marketing/en/concepts/pagination/).
- Filters: `status`, `trigger`.
- Sorting: newest first (`created_at` descending, then `id` descending); no other order.

# Create automation

URL: https://docs.smartchat.marketing/en/api/reference/automations/create_automation/

> Creates an automation. Without status it is a draft and never runs; status active runs it at once and needs the permission automations:run. Steps that call an address need webhooks:write, steps in connected apps need connections:run.

Creates an automation. Without status it is a draft and never runs; status active runs it at once and needs the permission automations:run. Steps that call an address need webhooks:write, steps in connected apps need connections:run.

`POST /v1/automations`

| | |
|---|---|
| Permission | `automations:write` ([all permissions](https://docs.smartchat.marketing/en/api/permissions/)) Activating an automation, or changing a running one, also needs `automations:run`. |
| Risk | Write (no outside effect) |
| Idempotency-Key | Required ([how it works](https://docs.smartchat.marketing/en/concepts/idempotency/)) |
| Safe to repeat | Safe to repeat with the same Idempotency-Key: the first answer comes back and nothing is done twice. |
| Rate limit class | `write` (120 requests per minute per key) |
| Confirmation | None |
| MCP tool | [`save_automation`](https://docs.smartchat.marketing/en/mcp/tools/save_automation/) |
| Since version | 2026-10-25 |

## What it does

- Changes data in your account. It does not send messages to contacts.
- May start automations of the account, and an automation may send messages. The call itself sends nothing.
- Setting it active lets messages go to contacts later. The call itself sends nothing.
- Safe to repeat with the same Idempotency-Key.

## Request

**Header**

| Name | Required | Description |
|---|---|---|
| `Authorization` | yes | `Bearer <key>` |
| `Idempotency-Key` | yes | A unique value for this operation, for example a UUID (1 to 255 visible ASCII characters). |

**Body** (JSON)

| Name | Type | Required | Description |
|---|---|---|---|

# Update automation

URL: https://docs.smartchat.marketing/en/api/reference/automations/update_automation/

> Changes name, trigger, steps or rules of an automation. Send only what changes; a list of steps replaces the whole list (keep the step ids). On an active automation this needs automations:run.

Changes name, trigger, steps or rules of an automation. Send only what changes; a list of steps replaces the whole list (keep the step ids). On an active automation this needs automations:run.

`PATCH /v1/automations/{automation_id}`

| | |
|---|---|
| Permission | `automations:write` ([all permissions](https://docs.smartchat.marketing/en/api/permissions/)) Activating an automation, or changing a running one, also needs `automations:run`. |
| Risk | Write (no outside effect) |
| Idempotency-Key | Optional ([how it works](https://docs.smartchat.marketing/en/concepts/idempotency/)) |
| Safe to repeat | Safe by nature. With the same Idempotency-Key the first answer comes back. |
| Rate limit class | `write` (120 requests per minute per key) |

## What it does

- Changes data in your account. It does not send messages to contacts.
- May start automations of the account, and an automation may send messages. The call itself sends nothing.
- Setting it active lets messages go to contacts later. The call itself sends nothing.
- Safe to repeat. With the same Idempotency-Key the first answer comes back.

# Set automation status

URL: https://docs.smartchat.marketing/en/api/reference/automations/set_automation_status/

> Sets the status to draft, active or paused. Active needs automations:run; draft is refused once the automation was active, because it would remove waiting messages (use paused). Templates not approved yet are listed in notices.

Sets the status to draft, active or paused. Active needs automations:run; draft is refused once the automation was active, because it would remove waiting messages (use paused). Templates not approved yet are listed in notices.

`PUT /v1/automations/{automation_id}/status`

| | |
|---|---|
| Permission | `automations:write` ([all permissions](https://docs.smartchat.marketing/en/api/permissions/)) Activating an automation, or changing a running one, also needs `automations:run`. |
| Risk | Write (no outside effect) |
| Idempotency-Key | Optional ([how it works](https://docs.smartchat.marketing/en/concepts/idempotency/)) |
| Safe to repeat | Safe by nature. With the same Idempotency-Key the first answer comes back. |
| Rate limit class | `write` (120 requests per minute per key) |
| Confirmation | None |
| MCP tool | [`set_automation_status`](https://docs.smartchat.marketing/en/mcp/tools/set_automation_status/) |
| Since version | 2026-10-25 |

## What it does

- Changes data in your account. It does not send messages to contacts.
- May start automations of the account, and an automation may send messages. The call itself sends nothing.
- Setting it active lets messages go to contacts later. The call itself sends nothing.
- Safe to repeat. With the same Idempotency-Key the first answer comes back.

## Request

**Header**

| Name | Required | Description |
|---|---|---|
| `Authorization` | yes | `Bearer <key>` |
| `Idempotency-Key` | no | A unique value for this operation, for example a UUID (1 to 255 visible ASCII characters). |

**Path parameters**

| Name | Type | Description |
|---|---|---|
| `automation_id` | string | Automation ID. |

**Body** (JSON)

| Name | Type | Required | Description |
|---|---|---|---|
| `status` | string | yes | draft is saved and never runs (an automation that was active cannot go back to draft, use paused). active runs and needs the permission automations:run. paused stops without losing waiting messages. one of: `draft`, `active`, `paused` |

## Examples

**curl**

```bash
curl -X PUT "https://api.smartchat.marketing/v1/automations/aut_0f8c1a2e4b7d4c3e9a5b6d7e8f901234/status" \

| `limit` | integer | no | Items per page (1 to 100, default 20). 1 to 100; default `20` |
| `cursor` | string | no | next_cursor from the previous page. Opaque; only valid with the same filters. up to 300 characters |
| `query` | string | no | Name, phone number or email, or part of it. Case does not matter. up to 100 characters |
| `tag` | string | no | Only contacts with this tag. Case does not matter. up to 60 characters |

| `created_before` | string | no | Only contacts created before this time (ISO 8601). up to 40 characters; format date-time |

## Lists, filters and sorting

- Items per page: `limit` from 1 to 100, default 20 (MCP: default 20, maximum 50).
- Next page: send `next_cursor` of the answer as `cursor`. The cursor only works with the same filters. See [Pagination](https://docs.smartchat.marketing/en/concepts/pagination/).
- Filters: `query`, `tag`, `optin_whatsapp`, `created_after`, `created_before`.
- Sorting: newest first (`created_at` descending, then `id` descending); no other order.

Lists messages across the account or of one conversation, newest first. Filters by direction and time. Use it to poll for new inbound messages.

`GET /v1/messages`

| | |
|---|---|
| Permission | `inbox:read` ([all permissions](https://docs.smartchat.marketing/en/api/permissions/)) |
| Risk | Read |
| Idempotency-Key | Not needed ([how it works](https://docs.smartchat.marketing/en/concepts/idempotency/)) |
| Safe to repeat | Safe: the call only reads. |
| Rate limit class | `read` (120 requests per minute per key) |
| Confirmation | None |
| MCP tool | Not available in MCP |
| Since version | 2026-10-25 |

## What it does

- Only reads data. It changes nothing and sends nothing.

## Request

**Query parameters**

| Name | Type | Required | Description |
|---|---|---|---|
| `limit` | integer | no | Items per page (1 to 100, default 20). 1 to 100; default `20` |
| `cursor` | string | no | next_cursor from the previous page. Opaque; only valid with the same filters. up to 300 characters |
| `conversation_id` | string | no | Only messages of this conversation. |
| `direction` | string | no | inbound = from contacts, outbound = from the account. one of: `inbound`, `outbound` |
| `created_after` | string | no | Only messages after this time (ISO 8601). up to 40 characters; format date-time |
| `created_before` | string | no | Only messages before this time (ISO 8601). up to 40 characters; format date-time |

## Lists, filters and sorting

- Items per page: `limit` from 1 to 100, default 20 (MCP: default 20, maximum 50).
- Next page: send `next_cursor` of the answer as `cursor`. The cursor only works with the same filters. See [Pagination](https://docs.smartchat.marketing/en/concepts/pagination/).
- Filters: `conversation_id`, `direction`, `created_after`, `created_before`.
- Sorting: newest first (`created_at` descending, then `id` descending); no other order.

## What it does

- Only reads data. It changes nothing and sends nothing.

## Request

**Query parameters**

| Name | Type | Required | Description |
|---|---|---|---|
| `limit` | integer | no | Items per page (1 to 100, default 20). 1 to 100; default `20` |
| `cursor` | string | no | next_cursor from the previous page. Opaque; only valid with the same filters. up to 300 characters |
| `status` | string | no | Only sequences with this status. one of: `draft`, `active`, `paused` |

## Lists, filters and sorting

- Items per page: `limit` from 1 to 100, default 20 (MCP: default 20, maximum 50).
- Next page: send `next_cursor` of the answer as `cursor`. The cursor only works with the same filters. See [Pagination](https://docs.smartchat.marketing/en/concepts/pagination/).
- Filters: `status`.
- Sorting: newest first (`created_at` descending, then `id` descending); no other order.

# Update follow-up sequence

URL: https://docs.smartchat.marketing/en/api/reference/followups/update_followup_sequence/

> Changes the name or status of a follow-up sequence, and the text or wait time of its steps. Setting active also schedules contacts who already confirmed. A changed text needs a new approval before it goes out.

Changes the name or status of a follow-up sequence, and the text or wait time of its steps. Setting active also schedules contacts who already confirmed. A changed text needs a new approval before it goes out.

`PATCH /v1/followup-sequences/{sequence_id}`

| | |
|---|---|
| Permission | `followups:write` ([all permissions](https://docs.smartchat.marketing/en/api/permissions/)) |
| Risk | Write (no outside effect) |
| Idempotency-Key | Optional ([how it works](https://docs.smartchat.marketing/en/concepts/idempotency/)) |
| Safe to repeat | Safe by nature. With the same Idempotency-Key the first answer comes back. |
| Rate limit class | `write` (120 requests per minute per key) |
| Confirmation | None |
| MCP tool | [`save_followup_sequence`](https://docs.smartchat.marketing/en/mcp/tools/save_followup_sequence/) |
| Since version | 2026-10-25 |

## What it does

- Changes data in your account. It does not send messages to contacts.
- May start automations of the account, and an automation may send messages. The call itself sends nothing.
- Setting it active lets messages go to contacts later. The call itself sends nothing.
- Safe to repeat. With the same Idempotency-Key the first answer comes back.

## Request

| `steps` | array of object | no | Changes to existing steps. Steps you leave out stay as they are. up to 10 items |
| `steps[].step_id` | string | yes | ID of a step of this sequence. |
| `steps[].text` | string | no | Message text of the step, at most 1024 characters. Use paragraphs, bold words in *stars* and an emoji: a long wall of text is refused. Placeholder: {{first_name}}. length 1 to 1024 |

Submits template drafts to WhatsApp for approval. Call without plan_id for a preview of what would be submitted, then again with the plan_id. Sends nothing to contacts; WhatsApp decides within a few minutes to 24 hours.

`POST /v1/template-submissions`

| Permission | `templates:submit` ([all permissions](https://docs.smartchat.marketing/en/api/permissions/)) |
| Risk | Send (reaches other people) |
| Idempotency-Key | Required ([how it works](https://docs.smartchat.marketing/en/concepts/idempotency/)) |
| Safe to repeat | Safe to repeat with the same Idempotency-Key: the first answer comes back and nothing is done twice. |

## What it does

- Changes data in your account. It does not send messages to contacts.
- Acts on a connected outside system.
- Needs a confirmation step (a preview first).
- Safe to repeat with the same Idempotency-Key.

> **Important** Messages are only sent to contacts who may receive them. The server checks the opt-in, never sends to unsubscribed contacts, respects the 24-hour window and uses approved templates only. See [Sending safely](https://docs.smartchat.marketing/en/security/).

## Request

**Header**

| Name | Required | Description |
|---|---|---|
| `Authorization` | yes | `Bearer <key>` |

**Body** (JSON)

| Name | Type | Required | Description |
|---|---|---|---|
| `template_ids` | array of string | yes | The templates to submit, from list_templates. up to 20 items |
| `plan_id` | string | no | From the preview call. Omit it to get a preview. |

| Permission | `webhooks:write` ([all permissions](https://docs.smartchat.marketing/en/api/permissions/)) |
| Risk | Write (no outside effect) |
| Idempotency-Key | Not needed ([how it works](https://docs.smartchat.marketing/en/concepts/idempotency/)) |

## What it does

- Changes data in your account. It does not send messages to contacts.
- Removes data. Only allowed for the few removals that keys may do (remove a tag, unsubscribe a webhook endpoint).
- Safe to repeat by nature; it needs no Idempotency-Key. A second call finds nothing to remove and answers with its not-found error.

> **Note** API keys cannot delete data. This call is one of the few exceptions.

Lists the deliveries of one endpoint, newest first, kept for 30 days. Each entry shows the attempt count, status, HTTP status and a short error. Filter by status to find failures.

`GET /v1/webhook-endpoints/{endpoint_id}/deliveries`

| | |
|---|---|
| Permission | `webhooks:read` ([all permissions](https://docs.smartchat.marketing/en/api/permissions/)) |
| Risk | Read |
| Idempotency-Key | Not needed ([how it works](https://docs.smartchat.marketing/en/concepts/idempotency/)) |
| Safe to repeat | Safe: the call only reads. |
| Rate limit class | `read` (120 requests per minute per key) |
| Confirmation | None |
| MCP tool | Not available in MCP |
| Since version | 2026-10-25 |

## What it does

- Only reads data. It changes nothing and sends nothing.

## Request

**Path parameters**

| Name | Type | Description |
|---|---|---|
| `endpoint_id` | string | Webhook endpoint ID. |

**Query parameters**

| Name | Type | Required | Description |
|---|---|---|---|
| `limit` | integer | no | Items per page (1 to 100, default 20). 1 to 100; default `20` |
| `cursor` | string | no | next_cursor from the previous page. Opaque; only valid with the same filters. up to 300 characters |
| `status` | string | no | Only deliveries with this status. one of: `pending`, `sending`, `delivered`, `failed` |

## Lists, filters and sorting

- Items per page: `limit` from 1 to 100, default 20 (MCP: default 20, maximum 50).
- Next page: send `next_cursor` of the answer as `cursor`. The cursor only works with the same filters. See [Pagination](https://docs.smartchat.marketing/en/concepts/pagination/).
- Filters: `status`.
- Sorting: newest first (`created_at` descending, then `id` descending); no other order.
