NDHM health Exchange APIs (HIP & HIU) are using HTPP 202 response code as acknowledgment response code and UHI/Beckn/DHP is using 200 HTTP response code as acknowledgment.
Technically 202 is the correct HTTP code for acknowledgment, so when UHI is adopting DHP it should also change HTTP code 200 to 202 from DHP, It will also bring consistency with other HIP/HIU APIs.
