I have a resource that accepts array of numbers. Each number is proceed interdependently, and computation fails are expected. How should I communicate to API client some of your numbers couldn't be proceed, but rest was successfully forwarded?
Trying to process partial POST of data in REST when some data is successful?
rest;api design
It seems the most straightforward method is just returning a XML or JSON, with the numbers and status.Per your description, I imagine a structure like this would suffice:{   requestDate: '2015-02-05 12:32'   results: [{       number: 1,       status: 'forwarded',   },   {       number: 2,       status: 'forwarded',   },   {       number: 3,       status: 'fail',   }]}I also think a HTTP Status of 200 is most indicated, as the client request was successfully processed. Also you can read in the spec (emphasis mine):10.2.1 200 OK...POST an entity describing or containing the result of the action;Edit: Researching a little more about the status codes, I think it may be better to use 207 Multi-Status:The message body that follows is an XML message and can contain a number of separate response codes, depending on how many sub-requests were made.[4]
