As you can see, there is field called rp_invoice_id which is The merchant’s own unique reference or invoice number, which can be used to uniquely identify a profile.

When creating API call CreateRecurringPaymentsProfile, how to pass this value, which field should I set in the API call?

Thank you

回答1:

You need to use the PROFILEREFERENCE parameter to pass in a value that will be returned via IPN in the rp_invoice_id parameter.

PROFILEREFERENCE

(Optional) The merchant's own unique reference or invoice number.

Character length and limitations: 127 single-byte alphanumeric characters

It will not work like this, newer versions of API are using REST calls.

To make this working you have to first download Paypal SDK. It is available at http://paypal.github.io/sdk/

Make sure you use official version of SDK, there might be chances that you may use different version and someone may be sitting there to steal your valuable information. My suggestion is before start working go through original documentation, to have an idea.

Once you install SDK, then you could use the example given in the link below

https://devtools-paypal.com/guide/recurring_payment_cc/php?interactive=ON&env=sandbox

This will make API call.

Also you can try with complete documentation available at https://developer.paypal.com/webapps/developer/docs/api/
