Support

Last updated 13 October 2026

Stuck on something, or is Hypamoon not doing what you expect? Email us at hello@hypamoon.com. A real person reads every message, and the same address works for the portal, the API, the MCP server and the apps you connect it to, such as ChatGPT or Claude.

When we reply

We aim to reply within one business day. Business days are Monday to Friday, Central European Time, except public holidays. If something is urgent, for example calls going to the wrong place, put urgent in the subject line.

What to include

The more of this you include in your first message, the faster we can help:

• the email address of your account, and the project it is about;
• whether it happened in test mode or live;
• what you did, what you expected and what happened instead;
• the error slug (such as insufficient_balance or validation_failed) and the request id from the X-Request-Id header, if you have them;
• the time it happened, and for a call the number that was called and the number it came from;
• for the MCP server: the app you use (ChatGPT, Claude, Cursor or another) and the tool that failed.

Never send us your API key, webhook secret or password. We never need them, and we'll never ask for them. If you think a key has leaked, revoke it in the portal at app.hypamoon.com first, then let us know.

Find it yourself

Most questions are answered in the docs:

• Quickstart: a site with a contact form, from your chat or with code.
• Phone, SMS and chat: from a test key to a number that answers.
• MCP server: connecting ChatGPT, Claude, Cursor and other agents.
• Errors: every error slug, what it means and how to fix it.
• Test mode: what works without a real phone or real money.
• All docs, including the API reference.

Live status is on status.hypamoon.com. If the service seems to be down, email us and we'll tell you what's going on.

Connected apps

You can see and revoke every app you connected to your project, such as ChatGPT or Claude, in the portal at any time. Revoking a connection stops it right away; your project, numbers and data stay as they are.

Report abuse

Did you get an unwanted call or text from a Hypamoon number, or do you suspect fraud, spam or impersonation? Email abuse@hypamoon.com. Include the number that called or texted you, the date and time, and what happened. For a site on hypamoon.app, the report form is quickest. You don't need an account to report abuse. We look into every report and can block calls, pause a project or close an account. How we handle reports says what we do and how fast.

For questions about your personal data, read our privacy statement. It explains your rights and how to use them.
