@oneglance Please go through this youtube link for HIP Data Transfer flow demonstrated.

@IntegrationSupport,
After we hitting “on-notify” API, we got multiple “request” calls for the same HIP ID in our callback environment like the image I uploaded

Because of this we can’t able to respond the correct request API, Why it is happening are we missing something?
And also, When data requesting from HIU, after patient granted the consent we are getting “notify” api callback but after responding for that with “on-notify” we didn’t get “request” callback. But when we requesting data from Patients PHR app, we are getting request api callback but in that scenario also we didn’t send data, we getting the issue I mentioned above.
Your response matter. Thanks in advance.!

Thank you,
