Variable	Required	Description
`MOLLIE_API_KEY`	Yes	Mollie API key (starts with live_ for production or test_ for test mode) Docs.

Create a Mollie account: Sign up at https://www.mollie.com. You can use test mode immediately after signup, before your account is fully activated for live payments.
Get your API key: In the Mollie Dashboard, go to Developers > API keys. Each website profile has a paired test key (test_…) and live key (live_…). Copy the key right away; treat it as a secret.
Configure the environment variable: Set MOLLIE_API_KEY to your test_ key while developing. Payments made with a test_ key are simulated and never charge real money. Switch to your live_ key once your account is approved for live payments.

Test mode and live mode are selected by the key prefix: test_ keys hit the same https://api.mollie.com/v2 endpoints but operate on simulated data.
Amounts are strings with the exact number of decimals for the currency, e.g. “10.00” for EUR.
Set a webhookUrl on payments in production so you receive status changes; polling get_payment also works for agent workflows.
