CSRF Token Validation Failed - OData Receiver ( HTTP Adapter )

[Nayak]

Scenario:

Sending PDF attachment from an external system to OData API_CV_ATTACHMENT_SRV.  S4Hana system

Problem:

We are using HTTP sender & Receiver Adapter. While sending the attachment through Postman we are getting the 403 forbidden response from the OData with error “ CSRF Validation Falied “
