To sign up for an account visit the sign-up page and fill in the details.

​

Credentials

The API credentials for Affirm are not available through a self-service dashboard and must be configured by our team. Please contact your Affirm representative to request that these credentials be provided to us.

​

Required fields

Based on your account setup, Affirm might require certain buyer details to be available during setup. In general, we recommend you provide as much of the buyer billing and shipping details, as well as any cart items before attempting an Affirm payment.

When not provided, your Affirm transaction might fail with a invalid_request_parameters error code, more specifically with a raw missing_fields error from Affirm.
