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?
First, you need to create new API key(s) for your Organization. You can do so in your Mollie Web App > Developers > API access tokens page.
Once you create an API key, you then need to safely store it, since after you exit the page, the keys will no longer be visible in the UI.
If you lost access to your keys, you need to rotate your keys and save the new keys on creation.
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.
