// 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:

// 	curl -X POST -k https://auth-sandbox.connect.abnamro.com:8443/as/token.oauth2 \
// 	-v \
// 	--cert TPPCertificate.crt \
// 	--key TPPprivateKey.key \
// 	-H 'Cache-Control: no-cache' \
// 	-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'
