An API key is a unique code for the API between your Mollie account and another website. With this key, the API recognises the user. You can enter a Test API key or Live API key when you’re connecting Mollie to a third party.
Test and Live API keys
You can use 2 different kinds of API keys: a Test API key and a Live API key:
- Test API key: With this API key, you can test the connection between a website and Mollie. You can test transactions without paying a fee to us.
- Live API key: You can use this API key to process real transactions. After using this key to connect the two websites, your customers can make payments.
Where can I find the API key?
- Log in to your Mollie Dashboard.
- Go to Developers > API keys.
- Click on Copy.
I changed my website profile. Do I need a new API key?
When you make changes to your website profile, you do not need to get a new API key. Your live API key remains valid and the link between your Mollie account and your webshop will remain the same.
