I have few questions about regular payments in PayPal, I went through the payment documentation to find the answers, but that did not help me.
These are the things that I need to know, I hope someone can help me with this.
I am using a standard PayPal payment account. So far, I have managed to create recurring payments using PayPal by sending NVP to paypal from the merchant's website on paypal.
Now I need to show recurring payment profiles on the seller’s website. So that customers can cancel, change recurring payments from the seller’s website without being redirected to paypal. Is it possible?
I think I should use the SOAP API for PayPal, because I can not do the work with the NVP API. So I installed the active merchant as described in this post . But I always get an error
This transaction is invalid. please return to the recipient's website complete the transaction using regular monitoring.
from paypal and it never sends me a token back.
I also got it in my magazine
Security header is not valid.
Is it because I use the sandbox API credentials or is it because I cannot use a standard Paypal account with a SOAP API?
