Errors

Every error is a JSON object with a single error string:

{ "error": "<message>" }

Status	Meaning
`400 Bad Request`	The body or a query parameter is invalid (the message names the step or field), an unknown `asUserEmail`, or a `fromEmail` that is not a verified sending identity
`401 Unauthorized`	Missing, malformed, expired, or revoked API key
`403 Forbidden`	The key lacks `read:sequences` or `write:sequences`, or lacks `send:emails` for a `SEND`-mode sequence
`404 Not Found`	No sequence with that ID in this workspace, or an `offeringId` that is not in it
`409 Conflict`	Enrolling into an archived sequence
`429 Too Many Requests`	Rate limit exceeded

Examples

{ "error": "steps.1: An EMAIL step needs both subject and bodyHtml." }

{ "error": "This sequence sends email without approval (sendMode SEND), so the API key also needs the send:emails scope." }
