0. Introduction
With PAYMILL, you have credit card payments and the SEPA direct debit procedure at your disposal. Before using the SEPA direct debit scheme throughout Europe, please check whether this is possible with your PAYMILL account. Therefore please contact the PAYMILL support.
1. Configuration in your PAYMILL account
At https://www.paymill.com you can create your PAYMILL account.
Your PAYMILL account is available to you directly in test mode.
Configure all required webhooks now under Development > Webhooks to be informed about status updates of your payment transactions in billwerk. The following webhooks are required:
- transaction.succeeded
- transaction.failed
- chargeback.executed
- refund.succeeded
- refund.failed
Enter as webhook URL for the production system: https://app.billwerk.com/PSPWebhooks/Paymill
and for the sandbox https://sandbox.billwerk.com/PSPWebhooks/Paymill
2. Configuration in your billwerk account
For the bilwerk payment configuration, go to "Settings > Payment > Payment settings > Paymill".
You need the following data:
- Private key
- Public key
You can find your private and public API key in the PAYMILL merchant center under Development > API Keys.
After entering your data press the "Save" button. Now you can select the wanted payment method in the billwerk payment overview. After selecting the method press the "Save" button here as well. The payment method is now ready to use.
If you want to use PAYMILL in an live environment you have to change the PAYMILL account to live mode. The settings in billwerk are the same for the live mode.
Hint: You can create a separate PAYMILL testaccount for the billwerk sandbox and keep on using it in test mode.
Please notice that the activation of your PAYMILL account can take several time by PAYMILL. The account has to be fully transformed to a live account and authorized before you can start using it as a payment method in billwerk.
