This guide will help you understand how payments via payment links work with the Mollie integration in RemOnline before you launch for real customers.
Details for testing payments
Mollie provides special test card numbers that allow you to simulate various payment scenarios without using real payment data. This allows you to check how your integration handles successful payments, declines, and other situations that arise when paying payment links.
American Express - 3782 822463 10005
Mastercard - 2223 0000 1047 9399
Visa - 4543 4740 0224 9996
The expiration date and CVV code can be entered in any format.
First and last names are required fields — you can enter any data for test payments.
The card brand allows you to check the dynamic display of the card logo in the card number field. Currently, test payments will always be processed using Mastercard.
Step 1. Check the Mollie integration connection
Make sure you have already set up and connected the Mollie integration with RemOnline.
To do this, go to the integration settings. Find Mollie and make sure the connection status is active.
Step 2. Create a separate cash register for test payments in RemOnline
To make test payments, we recommend creating a separate cash register in RemOnline.
Go to the Finance > Payments page and click the “+ Add cash register” button.
Specify the name of the account as a required field and set the account to cashless. All other account settings for testing can be arbitrary.
⚠️ Do not check the Virtual account checkbox, as such accounts are not supported in integration with payment systems and cannot be used during testing.
After testing payments, you need to delete payments in this account and delete the account. To do this, click on the gear icon in the upper corner of the account. Then click the delete button. This way, the company's financial reporting will not be affected.
Step 3. Making a test payment
After completing the preliminary settings and connecting the integration, we will make a test payment.
1. Go to the Finance > Payment links section and click + Payment link. Learn more about creating payment links using the Mollie integration.
☝️ To avoid mixing test and real payments, we recommend creating a separate test payer for test payments. This way, the payment history of the real customer will be accurate.
2. After creating a payment, open it via the link.
Step 4. Make a test payment
On the payment page, fill in the details for the test payment.
After entering the details, click the Pay button. Next, a list of scenarios will appear from which you can select the one you want to test.
After payment is made, the status of the payment link automatically changes to the appropriate one.
If the payment is successful, it will automatically appear in the account linked to the integration.
☝️ After completing testing, be sure to delete the account created for test payments, test payments, and the test payer. This will keep all your data in the reports up to date.
