How to Set Up Mollie Donations on WordPress

Prepare and verify your Mollie account

Create the account and complete Mollie’s current requirements for your organization and country: the organization profile, bank-account verification and website review. Mollie may ask about your activity, refund policy, legal entity and contact details, so have them ready before you announce a new donation page.

Read the provider’s terms for charitable fundraising and for each payment method you plan to enable. Availability, limits and onboarding steps differ by country and change over time. A method that appears in a test account may not be active for live payments until Mollie confirms it.

Choose methods that match your donors

Enable the methods your donors can realistically use and you can support. Too many options make a small form harder to scan. Think about the countries your donors live in, whether they give on mobile and whether you need one-time gifts, recurring gifts or both.

List the accepted methods honestly on the page. If a method is open only to donors in certain countries, let the provider decide eligibility instead of promising it to everyone, and show the currency and any likely bank conversion before payment starts.

Set up Mollie donations on WordPress safely

Use the connection method documented by the donation plugin or payment integration you chose. This may be an authorization flow or an API key, a credential that lets your website communicate with the payment provider. Treat API keys like passwords: never paste them into public pages, screenshots, support tickets or version-controlled files.

In FundCollector, Mollie is available in the Pro version for credit card payments. Connect it from the plugin’s payment settings and save the configuration, then check that the integration shows a clear connection state before you add it to a live form. If you use another WordPress tool, follow its own current documentation instead of applying these menu names to it.

Test every step before going live

Use test mode wherever the provider and your integration support it, and follow one payment from start to finish. Confirm each of these points:

1. The form validates the amount and required fields.
2. The donor is handed over to Mollie and returned to your site.
3. The donation shows the right status in WordPress.
4. The donor receives a receipt and you receive the administrator notification.

Then test a failed or cancelled payment, so you know what a donor sees when checkout does not complete. After switching to live mode, make one small live donation if your policies allow it, and check that the amount settles as expected and your WordPress record matches the Mollie dashboard. Watch the first real donations closely before sending a large campaign audience to the page.
