Transaction Services Generation 2 Client Authentication

The Simphony Transaction Services Generation 2 (STSG2) client authenticates with Open ID Connect (OIDC) credentials configured on each POS device. Before consuming other services, the POS device obtains a valid OIDC ID token from an OIDC server. For each service request, POS devices include their valid ID tokens in an HTTP authorization header (bearer authentication).

POS devices automatically obtain new ID tokens before the current one expires.
