Receive Forbidden message when request Uber receipt API - ruby-on-rails

Question

Document endpoint
https://developer.uber.com/docs/ride-requests/references/api/v1-requests-request_id-receipt-get
My application already has FULL ACCESS for request_receipt
However, in my Rails application, when I request to endpoint API at: /v1/requests/my-request-id-here/receipt I receive the full message like this:
#<HTTParty::Response:0x7f8738f833f8 parsed_response={"message"=>"Forbidden", "code"=>"forbidden"}, #response=#<Net::HTTPForbidden 403 Forbidden readbody=true>, #headers={"server"=>["nginx"], "date"=>["Wed
, 02 Nov 2016 14:31:37 GMT"], "content-type"=>["application/json"], "content-length"=>["42"], "connection"=>["close"], "x-uber-app"=>["uberex-nonsandbox", "migrator-uberex-optimus"], "strict-transport-sec
urity"=>["max-age=0"], "x-content-type-options"=>["nosniff"], "x-xss-protection"=>["1; mode=block"]}>
Do you have any suggestion? The Uber API for developer is poor!

Answer 1

The issue is most likely you did not request the new scope when you authorized the user and got the access token. Access tokens are limited to the scopes approved by the user (so even though it is enabled in the dashboard) you need to pass the 'request_receipt' scope when authenticating the user.
See more details in the authentication guide: https://developer.uber.com/docs/ride-requests/guides/authentication/introduction#step-one-authorize
If you create a new access token with the scope all should work as expected.
