PayPal has a built in security mechanism that expires a customer contract/abonnement after one year.
This authorization needs to be renewed by adding payment information again. The renewal follows the same steps taken during the registration process.
Step 1: Go to https://admin.yoochoose.net and login with the credentials you received after the successful registration process.
Step 2: Click on the link "Edit contract data" in the top. (If you have a german account the link name will be "Vertragsdaten ändern").
Step 3: A new window opens on the billwerk partner site. Billwerk is the partner responsible for the YOOCHOOSE's payment transactions.
In the billwerk customer portal, in the section “Ihre Zahlungsdaten” (Payment method), click “Ändern” (Change) to select your payment method.
Step 4: Select "PayPal" and enter your PayPal e-mail address. Click "Weiter" ("Next").
You will be redirected to the PayPal website where you can renew your PayPal contract/payment authorization.
Many thanks in advance!
