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 service_line_item_id that is not on the bill, or a blank reason, 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. A bill whose status is not processed returns 403.

Not found. The record does not exist or your user cannot access it.

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.
