OpenAPI Specification

openapi: 3.2.0
info:
  title: HoneyBook Projects API
  description: 'The HoneyBook API lets you read and write the data behind a HoneyBook account — contacts, projects, workspaces, smart files, tasks, notes, conversations and more.


    It is a JSON HTTP API. Every request is authenticated with an OAuth 2.0 access token, every response is JSON, and every endpoint lives under a single versioned base path.


    ### Base URL


    ```

    https://api.honeybook.com/api/v3

    ```


    The version is part of the path. A new major version gets its own path and its own documentation; endpoints in `v3` are not removed or changed in place.


    ### Making a request


    Send the access token as a bearer token:


    ```bash

    curl https://api.honeybook.com/api/v3/contacts \

    -H "Authorization: Bearer "

    ```


    ### How this documentation is organized


    **Guides** describe the conventions that apply across the whole API. Read Errors, Pagination and Filtering & Sorting once and they apply to every endpoint you touch.


    **API Reference** documents every endpoint, grouped by the resource it belongs to.


    ### Conventions worth knowing before you start


    - **Identifiers are opaque strings.** An id is a 24-character hexadecimal string. Treat it as an opaque token: do not parse it, and do not assume any structure or ordering.

    - **Timestamps are ISO 8601** in UTC, for example `2026-08-11T14:30:52Z`. Date-only fields are `YYYY-MM-DD`.

    - **Money is an object**, not a bare number — an amount together with its currency. Never assume a currency.

    - **Unknown query parameters are ignored, not rejected.** A misspelled filter name does not produce an error; it simply does not filter. Check your parameter names against the reference when a list returns more rows than you expected.

    - **Absent is not the same as empty.** A field that was not requested and a field that is genuinely empty are distinguished — see Relation Includes.


    The API is private. To get access, fill in the Request Access form.'
