Authentication and security

How authentication works #

Payaut uses API keys to allow access to the API. You can ask for an API key by contacting info@payaut.com. We expect the API key to be included in all API requests in the http Authorization header.

Payaut and security #

In order to exchange messages securely it’s necessary to grant your servers access to our domains:

• Sandbox: sandbox.payaut.com
• Live: api.payaut.com

Every connection to the domains above should target port 443 (https). If this is not possible, please contact us, so we can provide you with a list of IPs that should be released.
