Catalog discovery
The catalog is a list of all the domains and their descriptions. It can be discovered by sending a GET request to the /v1/sandbox/catalog endpoint.
Run a prior auth scenario
The scenario is a multi-step workflow that simulates a prior auth request. It can be run by sending a POST request to the /v1/sandbox/scenarios/{id}/run endpoint.
Inject HL7
Templates cover ADT admit, referral intake, prior auth submit, claim submit, eligibility check, and appointment scheduling. Injected messages map through your connection's HL7→FHIR rules and fire signed webhooks.
The HL7 templates are a list of all the HL7 templates and their descriptions. It can be injected by sending a POST request to the /v1/sandbox/hl7/inject endpoint.
Agent tooling
