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 |

## 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.
