Hi All,
We have an asynchronous service which needs to be serviced as synchronous API to a front-end application. The service responds with a 201 immediately with a requestId and eventually with actual response on a callbackUrl with the same requestId in response body. The callbackUrl is provided as part of request and be another Apigee endpoint of course. We have a need to make this service synchronous using Apigee. API will make the initial call and
- return an error code if anything other than 201 is received
- if 201 is received with requestId, request will be blocked until a response is received in callbackUrl for that responseId OR a timeout is hit. Delayed callback response will need to be ignored.
I have seen several references in the forum to make service callout asynchronously and later wait for responses. However, I am having hard time finding an API example to achieve what we need.
Thanks in advance, Ashish
