If you’re building with Cursor, Codex, Claude Code, or another AI agent, start here. This page gives your agent the fastest path into HookMyApp:
  • the CLI for live workspace, sandbox, and webhook operations
  • Agent Skills for HookMyApp-specific workflows inside your IDE
  • the Webhook Starter Kit as a clone-and-go runtime

​
Prerequisite

A human still needs to sign up for a HookMyApp account first. After that, your agent can take over: it logs the CLI in, starts a sandbox session, clones the starter kit, wires .env values, and verifies the round-trip.

​
HookMyApp CLI

For live operations, start with the CLI. 
npm install -g @gethookmyapp/cli
hookmyapp login
Use the CLI when the agent needs to inspect workspace state, start or stop a sandbox session, pull env values, set your own webhook URL, or send a test message from a terminal session. Every command supports --json for structured parsing. See the full CLI reference for the command surface.

​
Agent skills

If the agent works inside a codebase, install HookMyApp agent skills: 
npx skills add hookmyapp/agent-skills --all
The skill knows how to authenticate the CLI, connect your own WhatsApp number via embedded signup, pull env values, set your own webhook URL, and send a test message. Safety rules keep it from pasting tokens into chat or changing your live webhooks without your okay. See Agent Skills for the full capability and safety list.

​
Webhook starter kit

A working Node/Express receiver with HMAC signature verification, a send helper, and an auto-reply handler. Your agent clones it, points the CLI at it, and you have a webhook receiver running in two minutes. 
git clone https://github.com/hookmyapp/webhook-starter-kit.git
See the WhatsApp quickstart or Instagram quickstart for how it wires together and how the receiver shape stays identical from the sandbox to your own channel.

​
One-prompt setup

If you have agent skills installed, paste this into Claude Code, Cursor, or Codex and walk away: 
Integrate WhatsApp or Instagram into my app using HookMyApp. Install @gethookmyapp/cli, run hookmyapp login, start a sandbox session (hookmyapp sandbox start whatsapp or hookmyapp sandbox start instagram), pull env values into a .env file, and clone github.com/hookmyapp/webhook-starter-kit. Start it and forward webhooks to my receiver. Open the sandbox dashboard at the end so I can verify delivery.
