    Hi Sai13,

    Could you share full code?

    In general, we should keep URL under 2000 characters when sending GET request.

    You could consider using batch operations for Web API request.

    https://docs.microsoft.com/en-us/powerapps/developer/data-platform/webapi/execute-batch-operations-using-web-api

    Here is sample in C#:
