How to Integrate Mollie with systeme.io
Introduction
Mollie is a popular European payment provider for cards, iDEAL, Bancontact, and other local methods. On systeme.io, Mollie connects through a simple OAuth-style link—you sign in to Mollie and authorize the platform, without manually copying secret API keys like some other gateways. Merchants in the Netherlands, Belgium, and wider EU often choose Mollie as an alternative to iDEAL/Bancontact via Stripe.
This guide follows How to integrate Mollie with systeme.io.
What You Need
Step 1: Connect Mollie in systeme.io
- Log in to your systeme.io account
- Click your profile picture → Settings
- In the left menu, open Payment gateways
- Click Connect next to Mollie
- You are redirected to Mollie to log in or create an account
- After logging in, click Log in / continue as prompted
- Click Connect to authorize systeme.io to use your Mollie account
When the connection succeeds, Mollie appears as connected on the Payment gateways page in systeme.io.
Step 2: Select the Right Mollie Profile
If you operate multiple Mollie profiles (e.g. different brands or countries):
- Return to Settings → Payment gateways
- Click Change profile on the Mollie row
- Choose the profile that should receive funnel payments
- Click Save
Wrong profile = settlements and payment methods tied to the other business entity—double-check before going live.
Step 3: Configure Payment Methods in Mollie
To configure payment methods for your profile, go to the Mollie dashboard.
- Enable the methods you want (cards, iDEAL, Bancontact, SEPA, etc.) for that profile
- Complete any Mollie onboarding steps for each method
- Use test mode in Mollie for sandbox checkouts before switching to live
systeme.io does not replace Mollie’s method activation—buyers only see methods that are active on the linked Mollie profile.
Step 4: Use Mollie on Your Sales Funnel
After the account link works, enable Mollie on each funnel that should accept it—same pattern as Stripe or PayPal:
- Sites → Sales funnels → your funnel
- Funnel settings
- Enable Mollie (and disable competing gateways on that funnel if you want Mollie-only checkout)
- Save
Build or update your order form and offer , then run a small live or test payment and confirm it under Sales → Transactions.
Mollie vs Stripe for iDEAL
systeme.io supports iDEAL and Bancontact through Stripe ( dedicated guide) and Mollie as its own gateway. Pick one primary path per funnel—do not assume both show the same methods on one checkout without testing.
Troubleshooting
Connect button loops or fails
Pop-up blockers, wrong Mollie login, or incomplete Mollie KYC—finish verification in Mollie first.
Checkout missing iDEAL/Bancontact
Method not activated in Mollie Dashboard for the selected profile.
Payments in Mollie but not in systeme.io
Wrong profile selected; reconnect or Change profile; contact support with payment ID.
Contact systeme.io support with funnel URL and Mollie transaction reference.
