Get the active card-terminal provider
Reports which payment-service provider the network resolves to right now and how ready it is. Read this BEFORE runPaymentTerminalTest — it is the safe way to answer ‘is the card terminal set up’ without commanding any hardware. provider is the operator’s selection (the psp.provider network setting) falling back to the deployment default and finally to mock. enabled is the psp.enabled toggle, which DEFAULTS to true for any non-mock selection — it is not proof an operator opted in. configured means only that the provider’s credentials are present in the server environment; it says nothing about a physical reader being reachable, and it is always true for mock. So provider: "mock", configured: true means ‘wired to an in-memory fake’, NOT ‘ready to take cards’. availableProviders is the full selectable menu. No secret is ever returned. Credentials live only in the server environment — there is no API to set them.
Authorizations
Authorization: Bearer <token>. Accepts EITHER a Keycloak access token (scopes-in-token) OR an opaque POS session token; both resolve to the same pos.* scope vocabulary the route guards enforce.
Response
The resolved provider plus its enabled/configured flags and the full menu.
