Mollie Connect makes it possible for developers to build apps and have customers log in with their Mollie account. Basically, this feature allows you to easily build a product on the Mollie platform and make it available to all our customers. You can use Mollie Connect for things like making payments and issuing refunds, as well as sorting through transactions and payouts. Of course, your app must first request access from the customer to do so. Customers can choose to withdraw this access at any time. Our partners use Mollie Connect for ticketing software, donation platforms, payment links on invoices, data tools (insights), restaurant ordering platforms, booking software and payment pages, among other things.

Mollie Connect works via the Connect API. This API is built on OAuth 2.0 (Open Authorization), the industry standard when it comes to securely and confidentially providing data to apps. Through OAuth, you can access and carry out transactions on behalf of a Mollie customer’s account. OAuth uses “tokens”, which allow these actions to be performed without requiring the Mollie customer’s confidential data, such as their user name and password. The article “Working with access tokens” contains a brief explanation of how we use various tokens.
