We support four kinds of authentication:

Merchants enter their authentication key when they first activate your integration.

You can have the merchant’s API key as a header or a query parameter. You can configure the field name, and add multiple headers if you need them.

If you need merchants to enter an additional authentication parameter like their username and password, you can add those by creating settings and using the variable as the value.

We will automatically attach an Authorization header to your requests. We will add the merchant’s key after “Bearer”. We can only support bearer tokens that don’t expire, and we don’t support refresh tokens yet.

We will automatically attach an Authorization header to your requests. We will add the merchant’s key after “Basic”.

When OAuth is selected, you need to specify the Authentication end point, the grant type and the scope that your API expects to receive.

When OAuth is configured, customers will be asked to enter their Client ID and Client Secret to activate the integration.
