Use the guide that matches the task in front of you:
Need base URLs and environment details? Start with Integration methods and environment endpoints.
Need to understand how Verifone authenticates API calls? Go to API authentication.
Need to create or manage credentials in Verifone Central? Use Get your API Keys and Manage your API Keys.
Need the request header format for a specific auth scheme? Jump to BasicAuth or BearerAuth (JWT).
Access to your Verifone account and the correct environment.
The authentication method required by the API you are calling.
Credentials created and stored securely before you send live traffic.
The required authentication method depends on the API and flow you use. Confirm the auth scheme before building your request headers.
Confirm whether you are working in test or production.
Create or collect the required credentials.
Apply the correct authentication header.
Move on to your payment or wallet integration flow.
