201

Bad request. The model failed validation ({"errors": {field: [messages]}}), the JSON body could not be parsed, or a POST/PUT/PATCH request carried URL query parameters ({"error": "..."}). A blank message or an invalid due_date returns 400.

Unauthorized. The API token is missing or invalid, the user is not active, or the organization does not have API access.

Payment required. The organization is locked for an overdue invoice.

Forbidden. A required parameter is missing or a parameter is invalid (wrong type, value outside the allowed range, per_page above the maximum, bad date filter), or the path is not a valid endpoint.

Not found. The record does not exist or your user cannot access it. An assigned_user_id from another organization returns 404.

Too many requests. The rate limit (100 requests per minute per user by default) was exceeded. Check the X-Rate-Limit-Limit, X-Rate-Limit-Remaining and X-Rate-Limit-Reset headers, which are sent on every response.
