Errors

The complete list of response codes you can get, how the errors object is structured, and all the information about rate limits

Commerce Layer Metrics API uses HTTP response codes to show the success or failure of each API request.

• Codes in the 2xx range indicate success.

• Codes in the 4xx range indicate an error that failed given the information provided (e.g. due to a bad request, a failed validation, or an expired authentication).

• Codes in the 5xx range indicate an unhandled error (these are rare and should never happen).

This is the complete list of response codes you can receive when making requests to the Metrics API endpoints:

Code		Description
200	OK	The request was successfully processed and everything worked as expected.
400	Bad request	The request was unacceptable, often due to malformed syntax or sending an unsupported parameter at the first level (see examples).
401	Unauthorized	The access token was not present in the request, was expired, or didn't have enough permissions (see example).
404	Not found	The requested resource was not found, often due to a typo on the query type or resurce name in the endpoint.
405	Method not allowed	The request method is known by the server but has been disabled and cannot be used (Metric API supports POST request only — see example).
406	Not acceptable	The Accept header was not correctly set to application/vnd.api.v1+json (learn more about versioning — see examples).
415	Unsupported media type	The Content-type header was not correctly set to application/vnd.api+json (see example).
422	Unprocessable entity	The request body was well-formed but contains semantical errors on a nested level, often due to validation constraints (see examples).
429	Too many requests	The request was not accepted because you hit the rate limit.
500	Internal server error	Something went wrong on our end and is being investigated by our engineers.

Correct error handling is important. We recommend writing code that gracefully handles all possible API exceptions.

The error object

All the 4xx and 5xx responses include an error object in the response body. The object contains the list of errors with some extra information.

{
   "error": {
     "title": "...",
     "code": "...",
     "status": ...,
     "meta": {
       "errors": [
         {
           "field_name": [
             {
               "attribute_name": [ "..." ]
             },
             { ... }
           ]
           ...
         }
       ],
       "trace_id": "..."
     }
  }
}

Key	Type	Description
title	String	Descriptive information about the type of error.
code	String	The HTTP response code (e.g. BAD_REQUEST, UNAUTHORIZED).
status	Integer	The HTTP response status (e.g. 400, 401).
meta	Object	Any additional information about the errors in the request. Returned for 400, 404, 422, and 500 errors only.

Errors meta

For some types of error the meta object is also returned inside the error object. It contains extra information that can help you understand what went wrong with your call to the Metrics API and why it wasn't successful:

Key	Type	Description
errors	Array of objects	The detailed list of errors in the request (with information messages and reference to the related wrong keys). Returned for 400 and 422 errors only.
trace_id	String	The ID of the request (feel free to share it with us in case the information provided isn't enough for you to debug the error). Returned for every type of error except for 401.

Metrics API query validations are subject to a hierarchy — the filter section is validated before the query type one, hence errors in the parameters of the latter won't be thrown unless the ones in the parameters of the former are fixed (see example).

Rate limits

The requests you perform to the Metrics API are currently subject to the same rate limits as the POST requests to the Core API, based on the environment and the limit type:

Environment	Limit type	Max number of requests	Time window
Live	Average	200 (to all endpoints)	1 min
Test	Average	100 (to all endpoints)	1 min
Live	Burst	50 (per endpoint)	10 secs
Test	Burst	25 (per endpoint)	10 secs

The Core API /oauth/token endpoint you need to use for authentication is subject to stricter limits (max 30 reqs / 1 min).

IP addresses that exceed the rates above will be blocked until the frequency of the specific call drops below the allowed limit.

Examples

400 Bad request

Request

The following request tries to perform a Metrics API query but both the query type and the filter keys are empty objects:

curl -g -X POST \
  'https://{{your_domain}}.commercelayer.io/metrics/orders/date_breakdown' \
