Replace a campaign's sequence

PUT/v1/campaigns/{campaign_id}/sequence
Scope: campaigns:write

Replaces the campaign's whole sequence. To change one step, use Update a sequence step instead.

Send expected_updated_at, the campaign's updated_at as you last read it, to write only if nothing has changed the campaign since. If it has, nothing is written and the request answers 409 SEQUENCE_MODIFIED; retrieve the campaign again and retry. Without it, the write always lands.

A sequence is validated before it's saved:

  • variation_a is required and variation_b is optional. Each is a list of steps.
  • Step types are view_profile, linkedin_connection, conditional, linkedin_message and email.
  • A linkedin_connection step must be followed immediately by a conditional step with branches.yes and branches.no. Conditionals nest at most two deep.
  • linkedin_message steps are only allowed inside a yes branch.
  • email steps need subject and content.
  • delay is a number of days from 0 to 90.
  • Every step needs a unique integer id, and a sequence has at most 40 steps.

The easiest valid starting point is a sequence template.

Errors

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

StatusCodeMeaning
400VALIDATION_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.

400SEQUENCE_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.

401UNAUTHORIZED

The Authorization header is missing or malformed, or the API key is unknown or has been deactivated.

401API_KEY_EXPIRED

The API key is past its expiry date. Create a new key in the Victoria AI app.

403INSUFFICIENT_SCOPE

The API key doesn't have the scope this endpoint requires, such as leads:write.

403ORGANIZATION_DEACTIVATED

The organization that owns this API key has been deactivated.

404CAMPAIGN_NOT_FOUND

No campaign with this ID exists in your organization.

404NOT_FOUND

No endpoint matches the path. A resource ID in the path that isn't a valid UUID also answers NOT_FOUND.

409SEQUENCE_MODIFIED

The sequence changed after it was read. Retrieve the campaign again and retry.

413PAYLOAD_TOO_LARGE

The request body is larger than 1 MB.

429RATE_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.

500INTERNAL_ERROR

Something failed on our side. The response never includes internal details; quote its request_id when you contact support.

503UPSTREAM_TIMEOUT

A service the API depends on timed out. The request is safe to retry.

503AUTH_UNAVAILABLE

The API key couldn't be checked because the authentication service was unavailable. The request is safe to retry.
