}What Marsial does with WhatsApp
Marsial publishes and schedules content on your own WhatsApp accounts, always with your permission through OAuth, and shows you their statistics. It does not automate interactions (likes, follows or bulk messages) and does not read data from other people's accounts. You can disconnect the account at any time.

Questions about WhatsApp
Can I use my current number?
Yes, you verify it during sign-up. If you already use it in the WhatsApp Business app, you can keep using it there too.
Do I have to go through Meta's verification?
Meta's embedded sign-up does the verification in the same flow, in minutes, without creating your own app.
Who pays for templates?
Meta charges each template at its rates, directly to your WhatsApp Business account.
Can I connect an AI agent?
Yes, through webhooks or our MCP server, with hand-off to a person whenever you want.
