Get request is working but the post request is not working from DB2, In PostMan both are working

[AravinthEswaran]

Hi Everyone, 

Since Sharepoint ACS based Rest API is getting depreciated, i was working on to convert it to Graph based Rest API.

I have the App ID with necessary (Site.selected) access and I am able to perform CRUD operation through Postman application. 

When I replicate the same in the IMB DB2 I series, I can perform only Get request but not the post request. 

I am not sure on the source of the issue, as the same url, header & body while using in Postman action takes place. Sharepoint API is work for CRUD, so production is not impacted. 

Any idea like the firewall of Microsoft is blocking the Post/Patch/Delete request, but allowing only read access!!!!.

Since I mostly don't use personal mail, My response may be slow. 

Thanks
