Hi All,
Using below link I am trying update module cell data using Transactional APIs using Postman.
https://anaplanbulkapi20.docs.apiary.io/#WriteCellDataByCoordinateModule
But I am getting 403 Forbidden error. I am able to use all other GET request successfully.
Please find below screen shot:

I have full authorizations as shown below:


I am not sure what I am missing. Please help.
Regards
Mayank
