; This example requires the Chilkat API to have been previously unlocked.
; See Global Unlock Sample for sample code.

; This example sends the following CURL request:

; 	-H 'Content-Type: application/x-www-form-urlencoded' \
; 	-d 'grant_type=client_credentials&client_id=TPP_test&scope=psd2:payment:sepa:write psd2:payment:sepa:read'
