Python + Dataverse Series – #04: Create records in batch using Execute Multiple

Hi Folks,

This is continuation in this Python with Dataverse Series, in this blog post, we will see how can we create multiple records in a single batch using ExecuteMultiple in Python.

Please use the below code for the same…to make any calls using ExecuteMultiple…

print(f"Attempting to authenticate with tenant: {tenant_id}")

Note: Some part of this code is written with AI, please use with caution, but my main intention is to write about this possibility.

Hope this helps..
