See more ABN AMRO Examples

Demonstrates how to obtain an access token for an ABN AMRO online API using OAuth2 with the Client Credentials flow. Ruby

# 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'
