To identify who the calling application is please provide the User-Agent Header to the API
In 2027 all developers using our API is required to send the User-Agent Header so we can identify who the calling application is.
If this header is not sent to the server we will return 400 - Bad Request
Please adjust your code to prepare for this Breaking Change
Example:
If you are using our API to sync data to your ERP system you can write dynamics-365
