Akoya uses HTTP status and error codes to indicate the success or failure of a request. For status codes other than 200, the HTTP response body will contain an error entity.

HTTP Status CodesMeaning
100sInformational codes indicating that the request initiated by the browser is continuing.
200sSuccess codes returned when browser request was received, understood, and processed by the server.
300sRedirection codes returned when a new resource has been substituted for the requested resource.
400sClient error codes indicating that there was a problem with the request.
500sServer error codes indicating that the request was accepted, but that an error on the server prevented the fulfillment of the request.

We recommend implementing three (3) retries to help your app deal with short-lived, transient failures. The waiting time between retries should increase exponentially with each retry attempt.

Specific HTTP status and error codes may include:

HTTP Status CodesMeaning
403Access if forbidden. This may mean the route is incorrect. For example, if the version number is wrong.

Error body

Akoya data APIs support the ability to include debugging information with errors as defined in FDX 5.1 (RFC 01870). The debugMessage is not always present but will be included when possible.

🚧

FDX exception

Akoya error codes are consistent with FDX API 5.1 standards with the following exception:
The error code is returned as an integer rather than a string.

elementtypedescription
codeintegerRequired. Akoya returns the error code as an integer rather than a string (as specified by FDX). The code is a long term persistent identifier which can be used to trace error conditions back to log information.
messagestringRequired. This message is end-user displayable information which may aid in diagnosis and error reporting.
debugMessagestringNot required. Message used to debug the root cause of the error. Contents should not be used in business logic. These messages may change at any time and should only be used for troubleshooting an issue.

   "code":701,
   "message":"Account not found",
   "debugMessage": "No accounts were found for this customer."
}
