Frequently Asked Questions

What is a SESSION_ID and where do I get one?

A SESSION_ID is a one-time token you generate on the /session page by pairing your WhatsApp number. It's used once to set up your own personal deployment, then it expires.

Do I need MongoDB or a database for a personal deployment?

No. Personal deployments use plain disk-based auth storage. An embedded Postgres database is used automatically if you don't provide a DATABASE_URL — a database is optional, not required.

My deploy platform wiped my data after a restart — why?

Some free-tier hosts (Render, Railway) use an ephemeral filesystem by default, meaning local files are wiped between deploys unless you attach persistent storage. Attach a disk/volume, or set an external DATABASE_URL, to avoid this.

Can I run multiple bot instances?

Yes — the hosted Web and Telegram platforms already support many concurrent sessions. For personal deployments, each one is independent and tied to its own WHATSAPP_PHONE_NUMBER.

What's the difference between NexusBot and NexusAPI?

NexusBot is the WhatsApp bot itself. NexusAPI is a completely separate developer platform — an API marketplace for AI models, media tools, and scrapers, with its own account system.
