Support

March APIs normally replies within five Australian business days. This is an initial support target, not a guaranteed SLA.

Subscriptions

Use the provider contact or discussion tools on the RapidAPI listing. RapidAPI also handles plan, billing and subscription-account questions.

API issues

Open an issue in the public support tracker with the endpoint, response status, request ID, jurisdiction, rule version and a description of the expected behaviour. Do not include names, addresses, API keys, identity evidence or a full production request body.

Calculation discrepancies

Include the official authority or calculator URL, the date observed and a minimal synthetic example. A supported calculation with an unexplained official-source discrepancy blocks release and is investigated as a calculation incident.

Support scope

Support cannot determine first-home eligibility, interpret a contract, value a transaction or provide legal, tax, conveyancing or financial advice. Those questions require the relevant authority or a qualified professional.

MMarch APIs

Independent estimates only. Not legal, tax, conveyancing or financial advice.
