From signup to your first agent-updated deal in five minutes.
TL;DR — Create an account, generate an API key, connect your AI through MCP, and watch the CRM update itself while you work in Claude or ChatGPT.
Go to customermates.com/auth/signup. No credit card. The first three days are free, then you can pick a plan.
Open Profile → API Keys → New key. Copy the 64-character string immediately — it is shown once and never again.
Keep the key out of source control. Set it as an environment variable:
export CUSTOMERMATES_API_KEY=your-64-character-keyThe fastest path is the UI:
You can also do every step through MCP once connected (see step 5). Pick whichever is easier.
Company → Webhooks → New. For the URL paste a webhook.site endpoint. Pick at least contact.created and deal.updated. Save.
Edit one of the contacts you just made. Within a few seconds you should see the delivery show up at webhook.site with the full payload. That is your CRM telling your stack what changed.
Pick the client you actually use:
| Client | Guide |
|---|---|
| Claude Desktop | Connect Claude |
| ChatGPT | Connect ChatGPT |
| Cursor | Connect Cursor |
| Any MCP client | MCP overview |
Once connected, paste the setup prompt as your first message. The assistant will orient itself and ask what to do.

The assistant will tell you which tools it used and what changed. No copy-paste, no app switching.
