Quick Start

Three ways to integrate.

Choose the integration method that fits your workflow. Each option supports a different way to connect with Leadpages.

REST API

Create and manage pages programmatically with a standard RESTful API. Bearer token authentication. Available on Grow plan and above.

MCP Server

Connect AI agents like Claude, Cursor, and n8n directly to Leadpages. OAuth authentication. Available on all plans, including free trial.

Webhooks

Get notified when pages are published, updated, or deleted, or when a form is submitted. Configure endpoints from your account settings.

Authentication

Two ways to authenticate.

Use an API key for REST requests. Compatible MCP clients use a scoped OAuth flow.

API Key

Bearer Token

Generate an API key from your dashboard settings. Include it as a Bearer token in the Authorization header of every request.

Authorization: Bearer hp_live_your_api_key

Best for server-to-server integrations

Available on Grow plan and above

Scoped to your account

OAuth 2.0

Authorization Code Flow

Compatible MCP clients discover and complete the OAuth flow automatically. Users approve the requested scopes without sharing their Leadpages credentials.

Used by compatible MCP clients

Available on all plans

Access is limited to approved scopes

Example

Create or update a page in one request.

Send HTML to a stable slug. Reuse the same request to update it later.

RequestPOST
