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 `fromEmail` is not a verified sending identity, the audience is empty, or the launch is over today's sending limit
`401 Unauthorized`	Missing, malformed, expired, or revoked API key
`403 Forbidden`	The key lacks `read:campaigns` or `write:campaigns`
`404 Not Found`	No campaign with that ID in this workspace, or a tag, contact or offering in the body that is not in it
`409 Conflict`	The campaign's status does not allow this (editing a sent campaign, deleting a launched one), or the workspace's sending is paused
`429 Too Many Requests`	Rate limit exceeded

Examples

{ "error": "No tag named \"Farms\"." }

{ "error": "This campaign is SENDING and can no longer be edited. Create a new campaign instead." }

{ "error": "Only DRAFT campaigns can be deleted. This one is SCHEDULED; cancel it instead with POST /api/v1/campaigns/cmq2camp0alk34567890/cancel." }
