description: 'The ClickFunnels REST API that powers webhooks, native integrations, and Zapier lets you manage your ClickFunnels data, automate your workflows, and recreate ClickFunnels functionality in your own apps.
### For AI agents
This document is the catalogue: every operation ClickFunnels exposes over REST is described here, with a unique operationId, typed schemas, and the scopes it needs. It is served from `/openapi.json`, `/openapi.yaml`, `/api/openapi.{json,yaml}`, and `/api/v2/openapi.{json,yaml}` on the accounts host.
Three things it does not describe, each one request away:
- MCP server: the app-native Model Context Protocol server (Streamable HTTP, OAuth 2.1 with PKCE). Prefer it over raw REST when your client supports MCP - it describes itself at runtime.
- Skill guides, also as an Agent Skills index: one task guide per job (pages, blogs, products, orders, workflows, emails, courses, stats, external SDK pages). Read the guide that matches your job before your first write. llms.txt covers when to use ClickFunnels at all, how to get credentials, and how to behave around rate limits.
- Protected resource metadata (RFC 9728) and authorization server metadata (RFC 8414): the scope vocabulary and the OAuth endpoints. Dynamic client registration is for MCP clients only.
On ClickFunnels-owned API hosts (`myclickfunnels.com` and its subdomains), the OpenAPI specification responses and API authentication failures (401, or 403 for insufficient scope) carry those links in an RFC 8288 `Link` header, so clients can discover the documentation and authentication metadata from those responses. Requests sent through a customer''s custom domain keep the Bearer challenge but omit those discovery pointers.'

WorkspaceGrantForbidden:
description: "Forbidden — this request's workspace is closed to it.\n\nThree cases return this:\n\n* The access token is limited to specific workspaces (see the workspace selection made when\n the key was provisioned, or the workspaces approved on the OAuth consent screen) and the\n request acts on a workspace outside that set.\n* The access token is limited to specific workspaces and the request's workspace could not be\n determined at all. The gate is fail-closed, so a workspace-limited token is denied rather\n than allowed through when the target workspace is ambiguous.\n* The workspace's team has no active ClickFunnels subscription: it was canceled, is paused,\n or is locked out after failed payments. Reads and writes are both refused until the\n subscription is reactivated, and the body carries `\"code\": \"subscription_inactive\"`.\n\nA token with no workspace restriction never receives the first two."

BearerAuth:
type: http
scheme: bearer
description: 'A workspace API key or an OAuth access token, sent as `Authorization: Bearer <token>`.
Both carry the same scope vocabulary as the `OAuth2` scheme below. Category-only
scopes restrict access to the categories they name. Coarse wildcards remain additive:
`read contacts:read` reads every category, while `write contacts:read` can write every
category. Omit coarse scopes when restricting access to specific categories.
Legacy tokens with only coarse scopes retain their existing unrestricted access;
a bare `read` scope alone does not enforce read-only access.
'
OAuth2:
type: oauth2
description: 'OAuth 2.0 authorization code flow for REST integrations. Create a Platform Application
and follow `https://developers.myclickfunnels.com/docs/oauth-20` to connect users.
Authorization server metadata is published at
`https://accounts.myclickfunnels.com/.well-known/oauth-authorization-server`.
Dynamic client registration at `/oauth/register` is for MCP clients only; MCP-scoped
tokens must use `https://agents.myclickfunnels.com/mcp`, not the REST API.
Scopes are least-privilege by category. Ask for the two coarse wildcards (`read`,
`write`) only when an integration genuinely needs the whole workspace; otherwise ask
for the `<category>:read` / `<category>:write` pairs you use. `write` implies `read`
for the same category. Protected resource metadata (RFC 9728) for this API lives at
`https://accounts.myclickfunnels.com/.well-known/oauth-protected-resource`.
