How to test credit card recurring payment via REST API

[anyegongjue]

Hi there,

I want to apply a business account for my online shop. I use the REST API to build the payment gateway in my website. I want to accept credit card when client subscribes my monthly service.

Now I tested the API implementation using a sandbox business account and a sandbox business pro account and none of them can accept the credit card subscriptions.

Do I need to do some special settings to get it working?

This is the API document I followed.

https://developer.paypal.com/docs/api/overview/

Thanks.
