Blocking specific merchants on authorization control

Blocking specific merchants on authorization control

Hello,

I'm having trouble understanding the documentation provided for authorization control, specifically on blocking specific merchants. Here's one detail regarding this: "Your program’s default authorization behavior can block all merchants by default, requiring you to whitelist allowable merchants, or allow all merchants by default, requiring you to blacklist blocked merchants. Make sure you know your program’s default behavior before designing your controls." My question is how do I know my program's default behavior? I'm not sure if it currently is allowing all merchants so that if I create a new auth control with merchant scope it will restrict those entries. Let me know if there's an api or guide to check the program's default behavior. Also, please clarify if whitelisting/blacklisting is done through the merchant scope field or elsewhere.

Hi @dev ! The default authorization that you are working with in the Public Sandbox is to allow all merchants. To associate the auth control you can put the MCC group token in the "merchant_scope.mcc_group" field. 

Let me know if this helps or if you have any more questions.

Thanks!

Jess
