Update a sequence step

PATCH/v1/campaigns/{campaign_id}/sequence/steps/{step_id}

Scope: campaigns:write

Changes one step's message, subject, content or delay. The step is found by its id anywhere in the sequence, including inside conditional branches, and the whole sequence is validated again before it's saved.

If the sequence changed after it was read, the request answers 409 SEQUENCE_MODIFIED instead of overwriting the other change. Retrieve the campaign again and retry.

Errors

Errors share one JSON body: success, error, message, optional details, and request_id.

Status	Code	Meaning
400	VALIDATION_ERROR	The request didn't match the endpoint's schema: a missing or malformed field, a bad query parameter, or a value out of range. `details.errors` lists each failing field with its `field`, `message` and `type`.
400	NO_SEQUENCE	The campaign has no sequence, so there's no step to update.
400	SEQUENCE_VALIDATION_FAILED	The sequence breaks a structural rule, such as an unknown step type or a `linkedin_connection` step without a `conditional` after it. The message lists every rule that failed.
401	UNAUTHORIZED	The `Authorization` header is missing or malformed, or the API key is unknown or has been deactivated.
401	API_KEY_EXPIRED	The API key is past its expiry date. Create a new key in the Victoria AI app.
403	INSUFFICIENT_SCOPE	The API key doesn't have the scope this endpoint requires, such as `leads:write`.
403	ORGANIZATION_DEACTIVATED	The organization that owns this API key has been deactivated.
404	CAMPAIGN_NOT_FOUND	No campaign with this ID exists in your organization.
404	STEP_NOT_FOUND	No step with this ID exists in the campaign's sequence, including inside conditional branches.
404	NOT_FOUND	No endpoint matches the path. A resource ID in the path that isn't a valid UUID also answers `NOT_FOUND`.
409	STEP_ID_AMBIGUOUS	More than one step in the sequence has this ID, so the update can't tell which one to change.
409	SEQUENCE_MODIFIED	The sequence changed after it was read. Retrieve the campaign again and retry.
413	PAYLOAD_TOO_LARGE	The request body is larger than 1 MB.
429	RATE_LIMITED	Too many requests for this API key: more than 100 a minute to one endpoint, or 600 a minute in total. Retry after the number of seconds in the `Retry-After` header. See Rate limits.
500	INTERNAL_ERROR	Something failed on our side. The response never includes internal details; quote its `request_id` when you contact support.
503	UPSTREAM_TIMEOUT	A service the API depends on timed out. The request is safe to retry.
503	AUTH_UNAVAILABLE	The API key couldn't be checked because the authentication service was unavailable. The request is safe to retry.

Response headers

Header	Description
`X-Request-ID`	Correlation ID for the request, also returned as `request_id` in error bodies. Send your own `X-Request-ID`, up to 128 letters, digits, `.`, `_`, `:` or `-`, and it's used instead.
`RateLimit-Limit`	Requests allowed to this endpoint per minute.
`RateLimit-Remaining`	Requests you can still send to this endpoint right now.
`RateLimit-Reset`	Seconds until the endpoint's full limit is available again.
`Retry-After`	On a `429`: seconds to wait before retrying.
