Overview

What is the Merion API?

api.merion.com.au is the system-of-record hub that powers Merion's partner and client portals. It handles debt referrals, case updates, partner intake, form submissions, and billing events. The hub is not a general-purpose open API — most routes require an authenticated bearer token issued by auth.merion.com.au, or a portal-scoped session token. Access is available to approved partners and integrators only.

Public surface

What is publicly accessible?

Without authentication, the following endpoints respond:

GET https://api.merion.com.au/health

JSON status response. Useful for uptime monitoring.

GET https://api.merion.com.au/docs

Human-readable API documentation page.

GET https://api.merion.com.au/openapi.yaml

Machine-readable OpenAPI 3.x specification.

GET https://api.merion.com.au/.well-known/openid-configuration

OIDC discovery document (served by auth.merion.com.au).

POST https://api.merion.com.au/public/forms/{key}

Marketing and partner form intake. No token required. See the Forms API docs.

All other routes require a bearer token (OIDC, ES256, PKCE S256) or a portal session token. Unauthenticated requests to protected routes return 401 Unauthorized.

Access

Who can integrate?

The API is intended for:

• Approved referral partners — accountants, bookkeepers, and business advisers in the Merion Partner Programme who need to submit referrals programmatically.
• Approved integrators — software platforms or internal teams building integrations against Merion's platform on behalf of a contracted client.

To request access, email [email protected] with a brief description of your use case. The Merion team will issue credentials via the partner onboarding flow.
