My both API are running in the beginning, However I want them to be run sequential order


Actually, I m using 2 API in my project First API(Post) for raising a request and based on that i got output in the next 15 second, however, my second (Get) API start looking for results in the very beginning of the flow results it capture the result of old run instead of the latest one generated by the first API.

Need some help to let that run in sequential order, So my 2 API(GET) will give the latest result instead of old result.
