Add your live_key and your test_key as you normally would with Mollie. However, you will notice that we now have some additional fields:
- Redirect URL
- Client ID
- Client Secret
You will need to create a Mollie App in your mollie dashboard > developer. There it will ask for the domain and Redirect URL. Simply copy the Redirect URL from the above field and paste it. Once created, the Client ID and Secret will become visible. Now simply copy & paste those to your payment settings in WooCommerce (see above image).
Approving Mollie App
Make sure you request the approval of the newly created Mollie Connect app via email to Mollie: firstname.lastname@example.org
