API
The Maxforms API: OAuth 2.0 authentication, the JSON:API form, embed and webhook endpoints.
Build on Maxforms: OAuth 2.0, workspace-bound access tokens, and a JSON:API surface for forms, embeds, submissions and webhooks. The guides below cover authentication and the flows; the API reference lists every endpoint, parameter and example, generated from the code.
- API reference Every endpoint, parameter and example, generated from the code.
- Overview and authentication Base URLs, the OAuth 2.0 Authorization Code flow, scopes and workspace binding, the JSON:API document shapes, and rate limits.
- Build an embed integration Let your users pick one of their Maxforms forms and drop it into a page: OAuth, the form list, the option descriptor, and the embed endpoint.
- Webhooks Subscribe a target URL to new submissions, verify the signed delivery, and handle retries. The endpoints Zapier itself uses.
