Connect Claude to WebForms

Things to ask Claude
- “Which of my forms gets the most spam?”
- “Show me the latest enquiries from the contact form and summarise what people want.”
- “Find every submission that mentions a refund.”
- “How much of my monthly allowance is left?”
- “Create a waitlist form with name and email, and give me the HTML to paste.”
- “Did any webhook deliveries fail this week? I fixed the endpoint, so replay them.”
- “Which visitors started the project enquiry form but never sent it?”

Using an API key instead
If you would rather not sign in, create an API key under Settings, API keys in WebForms (tick the write scopes you want it to have) and send it as a bearer token. Keep the key out of shared or committed files. In Claude, put it in the connector's request headers instead of signing in.
Authorization: Bearer wf_live_your_key
Worth knowing
- Claude connects from Anthropic's servers, not from your computer, which is fine: WebForms is a public URL.
- On Claude's free plan you can add one custom connector.
