Request headers

The following table describes HTTP request headers of particular interest to Matrix Routing v2 service clients. Note: There are no required headers in this endpoint.

Optional headers	Description
Tracking-ID	Specifies an identifier for the request. It can be used to trace a call. The value must match the regular expression `'^[a-zA-Z0-9-]{1,100}$'`. An example of the format that matches this regular expression is UUID: (e.g., `9ac68072-c7a4-11e8-a8d5-f2801f1b9fd1` ). For details check RFC 4122. If specified, it is replicated in the Tracking-ID response header. It is only meant to be used for support and does not involve tracking of you or your users in any form. Value: An `identifier` for the request.

Response data

HTTP status codes

Code	Meaning & possible causes
`200`	Request was successful and information about a matrix job's current status will be returned to the client.
`403`	Forbidden: The API Key is missing, inactive, invalid, not entitled to use Matrix Routing v2 API, or exceeded the available quota. This can also occur when using HTTP instead of HTTPS.
`404`	The requested resource could not be found, possible reasons: A job with the provided Id doesn't exist. A job with the provided Id did exist but the retention period has passed, and the status is no longer available. The provided job Id and the API Key do not match. URI path not found.
`405`	Method Not Allowed: The client used an HTTP method other than GET.
`414`	Requested URI is too long: Indicates that the URI requested by the client is longer than the server is willing to interpret.
`429`	Too Many Requests: Quota was exceeded for the API Key.
`500`	An error occurred while processing the request. Please try again later.
`502`	Internal network connectivity issue. Please try again later.
`503`	Service currently unavailable. Please try again later.
`504`	Internal network connectivity issue or a request that has taken too long to complete. Please try again later.
`596`	Service not found. Request contains an incorrect FQDN and/or path.

Response headers

The following table lists HTTP response headers of particular interest to Matrix Routing v2 service clients.

Header	Description
Access-Control-Expose-Headers	A comma separated list of HTTP header names that browsers are allowed to access. Value: Content-Length
Access-Control-Allow-Origin	A header instructing browsers to allow customer websites to contact the Matrix Routing v2 service. Value: `*`
Content-Encoding	The Matrix Routing v2 service applies gzip compression to the response if it is requested by the client with the Accept-Encoding header. Value: `gzip`
Content-Type	The format of the response. Value: `application/json;charset=utf-8`
Tracking-ID	An identifier for the request. If the Tracking-ID header was specified, it is replicated in the response. Otherwise, it is generated automatically by the service. It is only meant to be used for support and does not involve tracking of you or your users in any form. Value: An `identifier` for the request.

Successful response fields

Primary fields
Field	Description
`jobId` string	Unique matrix Job Id.
`state` string	Possible values: `Submitted` - request hasn't been validated yet. `Validated` - request is validated and it's being processed. `Completed` - request is processed and results are available for download. `Failed` - processing of the given job could not be successfully completed. The value list of the `state` field may be extended with new values in the future, e.g., `Paused`. Clients should be prepared for this. Only `Completed` and `Failed` states should be considered as the final states of a job. Encountering any other state means that the client should check the status of the job again in the future. When a job enters the `Completed` state, its result can be downloaded using the Asynchronous Matrix Download endpoint. Moreover, the Asynchronous Matrix Status and Asynchronous Matrix Download endpoints will now return success and failure statistics for such a job. When a job enters the `Failed` state, details of the failure will be available in the response of the Asynchronous Matrix Status endpoint. Its result will not be available for download.
`detailedError` object	Optional field, present in an HTTP 200 response body only when the state is `Failed`. For example, when an asynchronous submission has failed validation, then the details about the failure will be available in this field. The content of this object is defined the same as in the case of an error response: `detailedError` object.
`statistics` object	Optional field, present when the state is `Completed`. `statistics` object
statistics object
Field	Description
`totalCount` integer	Total number of routes within this matrix.
`successes` integer	Number of successful routes within this matrix.
`failures` integer	Number of failed routes within this matrix.
`failureDetails` array	When there are any failed cells, this field contains the details about the failure(s). `failureDetails` array
failureDetails array
Field	Description
`code` string	One of the defined error codes.
`count` integer	Number of failed routes within this matrix caused by errors having given `code`.

Error code hierarchy

List of predefined, hierarchical, human-readable error codes.

Top level codes relate to HTTP error codes.
They may be refined by error codes in details or innerError.
Further levels of refinement are possible by nesting innerError inside innerError.

In the future, the list may be extended with additional codes. New or existing codes may be introduced as children of codes already present in the hierarchy. The application must be ready for the occurrence of an unknown error code (e.g., by stopping error processing at the last understood level of detail).

Each of the following error codes has a scope assigned. Scope assignment is subject to change and extension. Possible scopes are:

job - the error code concerns the whole job.
- It may be included in the optional detailedError structure.
cell - the error code concerns failed processing of one of the matrix cells.
- Codes in this scope may be included in the optional failureDetails array.

Error code	Description	Scope
`MATRIX_NOT_FOUND`	Top level code for requests which failed with an HTTP `404` status code. May be caused by requesting the Id of a matrix job which: Does not exist. Doesn't match the API Key provided. Has the job result as not ready. Is no longer available because the 24 hour retention period has passed.	`job`
`NOT_FOUND`	Top level code for requests which failed with an HTTP `404` status code, caused by providing an incorrect request path.	`job`
`BAD_REQUEST`	Top level code for requests which failed with an HTTP `400` status code. Most probable cause is a failed request parameters validation. Current possible details: `BAD_ARGUMENT` `MALFORMED_BODY`	`job`
`INTERNAL_SERVER_ERROR`	Top level code for requests which failed with an HTTP `500` status code. The service cannot handle the request right now, an unexpected condition was encountered.	`job`
`SERVICE_UNAVAILABLE`	Top level code for requests which failed with an HTTP `503` status code. The service cannot handle the request right now, this is certainly a temporary state.	`job`
`FORBIDDEN`	Top level code for requests which failed with an HTTP `403` status code. Current possible details: `OVER_TRANSACTION_LIMIT`	`job`
`BAD_ARGUMENT`	One of the request parameters did not pass validation. The optional `target` field may contain the name of the related parameter, or the location inside a JSON object in the request POST body. Current possible details: `BAD_ARGUMENT` Current possible inner errors: `ILLEGAL_PARAMETER` `MISSING_REQUIRED_PARAMETER` `INVALID_PARAMETER_VALUE`	`job`, `cell`
`OVER_TRANSACTION_LIMIT`	Client has exceeded the transaction limit.	`job`, `cell`
`MALFORMED_BODY`	POST body is not properly formatted.	`job`
`ILLEGAL_PARAMETER`	Unsupported request parameter was specified.	`job`
`MISSING_REQUIRED_PARAMETER`	One of the required parameters was not provided.	`job`
`INVALID_PARAMETER_VALUE`	The value of one of the parameters is invalid.	`job`
`UNKNOWN`	Unknown error has occurred.	`cell`
`MAP_MATCHING_FAILURE`	One of the input points (origin, destination) could not be matched to the map because there is no known drivable section near this point.	`cell`
`NO_ROUTE_FOUND`	No valid route could be found for the given origin and destination pair.	`cell`
`CELL_TIMEOUT`	Failed to calculate route summary for the given origin and destination pair within timeout.	`cell`
`OUT_OF_REGION`	The distance between the given origin and destination pair is too long to calculate the route, considering other requested options. See the API Limitations table on the Asynchronous Matrix Submission page for more information.	`cell`
