Postman Flows block does not send Authorization header

Help Hub
1

In a Postman Flow I have two GET HTTP blocks.

Both:

  • Call the same backend and use the same environment
  • Use OAuth 2.0
  • Work correctly when run with “Send” in the normal request tab

However, inside the Flow:

  • One GET works (200 OK)
  • The other returns 401 Unauthorized because the Authorization header is not sent

Try manually adding the Authorization header in the HTTP block
Authorization : Bearer ((access_token}}
