Initially, they will receive a text message or email (or both, depending on what you have selected) with a URL/website/link (https://PPPco.de) to complete their Paypa Plane account. This is their unique code to the agreement you have set up, and following the process will allow them to agree to the arrangement and commence payments.
By sending a 'test' Payment Arrangement, you can experience exactly what your customers experience when on-boarding their payments with Paypa Plane.
To send a test payment request, build a payment request in the same way that you usually would for a client.
In the final 'Summary' step, before pressing SEND, use the Pen icon to change it from a 'Live Request' to a 'Test' one. This will allow you to proceed through the payment information without actually taking a payment from yourself.
Note: do not use test when sending a live agreement because the resulting payment will not actually be processed.
