getting Invalid Merchant or Merchant doesn't exist! with payflow when opening payflow link

Question

I am referring to this article : https://www.paypal.com/us/smarthelp/article/how-do-i-integrate-my-website-with-payflow-link-(basic)-ts1245

We are performing a test transaction on a payflow account, using html/javascript code and for that we are passing test data for the following fields: LOGIN, PARTNER, AMOUNT, TYPE.

On submit we are posting the above data to https://payflowlink.paypal.com. It is returning the following error message:

Error: Invalid Merchant or Merchant doesn't exist!

What mistake am I making?

Also, I want to know that the above approach is correct for payflow transactions using a custom website integration?

Answer 1

If this is not for a live transaction, use https://pilot-payflowlink.paypal.com

we are passing test data for below fields LOGIN, PARTNER,AMOUNT,TYPE.

Your question should include the form you are using and the data you are passing, since invalid data here may be precisely the problem.

Regardless, why are you using the 15+ year-old Payflow Link instead of the much newer and nicer standard PayPal checkout with its black Debit or Credit Card button? ....
