Merchant API reference ​

Browse and try every Merchant API endpoint here — this reference always matches the live API, since it's generated from the current OpenAPI schema.

Before trying a request, generate a merchant API key: sign in to the merchant console, open API keys in the sidebar, and create a key. Requests to the public Merchant API authenticate with an X-TenaBill-Api-Key header set to that key — the reference below has an Authentication panel where you can paste it in so "Try it" requests are sent with the header attached.
