Postman Batch Requests for POST - GET - PUT - PATCH

Generally, batch requests are supported in the Odata service, the excel add-ins in Dynamics 365 for finance and operations use Odata batch to communicate in a single request but how can we leverage it in Postman.

Using Excel add-in then add records and submit to Dynamics 365 for finance and operations, see how the odata batch framework works. This can be done from POSTMAN too and you need to use header and body.

1. Get Dynamics 365 for finance and operations authorization

This is a result

2. Create a new POST request in Postman with header

URL: {{resource}}/data/$batch 

Content-Type: multipart/mixed;boundary=batch_d63a-e9be-2927

3. Modify the Body in Postman
