The Zanda Public API is available

The API gives you read access to a practice's scheduling and billing data, versioned under /api/v1. Nine resources are available, each as a list and as a single record: appointments, billable-items, client-profiles, insurers, invoices, locations, payments, practitioners and referrals.

Authenticate with the practice's API key in an X-API-KEY header. Lists are paged with page and pageSize, which returns 10 records by default and 25 at most, and every response carries links to its related records so you do not have to build the next URL yourself. Requests are rate limited.

Reference documentation for every endpoint is published with the API.
