Terminal API - Overview

​

Terminal Pairing

To integrate an Authsignal terminal with your point of sale system, you’ll need to obtain the terminalId from an on-boarded device. This unique identifier is required to authenticate requests to the payment session APIs from your point of sale terminal.

​

Terminal Request Identification

The Authsignal Payment Session API uses your terminalId as a value in the x-authsignal-terminal HTTP request header to identify requests.

curl --header 'x-authsignal-terminal: YOUR_TERMINAL_ID' https://api.authsignal.com/v1

​

Region selection

Authsignal’s server SDKs default to the US (Oregon) region. If your tenant is in a different region, a different base URL must be configured.
