Responses

The Mews POS API follows the JSON:API specification for formatting HTTP responses. Content-Type is set to the JSON:API media type application/vnd.api+json.

A typical JSON response looks like this:

{
  "data": {
    "type": "invoices",
    "id": "12345",
    "attributes": {
      "customer_uuid": "customer-uuid",

      "total_amount": "100.00",
      "created_at": "2024-07-19T12:34:56Z",
      "updated_at": "2024-07-19T12:34:56Z"
    },
    "relationships": {
      "customer": {

Response codes

Code	Meaning
200	OK Indicates that the request has succeeded.
201	Created Indicates that the request has succeeded and a new resource has been created as a result.
202	Accepted Indicates that the request has received but not completed yet.
204	No Content The server has fulfilled the request but does not need to return a response body.
400	Bad Request The request could not be understood by the server due to incorrect syntax. The client should not repeat the request without modifications.
401	Unauthorized Indicates that the request requires user authentication information.
403	Forbidden Unauthorized request. The client does not have access rights to the content. Unlike 401, the client’s identity is known to the server.
404	Not Found The server cannot find the requested resource.
408	Request Timeout Indicates that the server did not receive a complete request from the client within the server’s allotted timeout period.
409	Conflict The request could not be completed due to a conflict with the current state of the resource.
422	Unprocessable Entity The server understands the content type and syntax of the request entity, but still the server is unable to process the request for some reason.
429	Too Many Requests The user has sent too many requests in a given amount of time (“rate limiting”).
500	Internal Server Error The server encountered an unexpected condition that prevented it from fulfilling the request.
