Nexus

Quickstart

How Nexus Bots works

Go from signup to a working Website bot with no external token, or choose another channel and follow its setup path without leaving the builder.

  1. 1

    Create your account

    Join with an invite or open registration, then verify your email when prompted.

  2. 2

    Choose where it lives

    Website is first and needs no token. Telegram, Discord, Slack, WhatsApp, Messenger, and Instagram are one click away with setup requirements shown up front.

  3. 3

    Preview a starting flow

    Pick a platform-matched template by looking at its real graph, install one from the store, or choose Blank canvas last.

  4. 4

    Configure and test

    The canvas highlights the first unfinished node. Add a connection or channel credentials, then send a dry-run message in the Test panel.

  5. 5

    Deploy when it is ready

    Save and deploy from the builder. Nexus checks triggers, destinations, credentials, plan gates, and Website origins on the server.

Scheduled flows and long waits

Start a Discord, Slack, Telegram, WhatsApp, Messenger, or Instagram flow with an On Schedule trigger to run every few minutes, hourly, daily, or weekly in a chosen timezone. Set the destination, deploy it, and use Run now for an immediate live check. Plan interval limits apply, and a repeatedly failing schedule pauses automatically so it cannot retry forever.

Delay nodes support seconds, minutes, hours, and days. Waits longer than five seconds are saved to the durable execution queue and resume at the next node, even after a worker restart. Website bots remain synchronous, so they reject long waits.

Platform notes

  • Telegram deployment requires APP_URL to be a public HTTPS origin so Telegram can reach the webhook.
  • Discord requires Message Content intent and an always-on worker connected to the same database and encryption key.
  • Slack requires a Bot User OAuth token, Signing Secret, Events API subscriptions, and a public HTTPS APP_URL.
  • WhatsApp Cloud API requires Pro or Team, a permanent access token, App Secret, Phone number ID, WABA ID, a public HTTPS callback, and the messages webhook subscription. Free-form replies are limited to 24 hours after the customer's latest message; use an approved Template node outside that window. See the WhatsApp setup guide.
  • Messenger and Instagram require Pro or Team, a Facebook Page, signed Meta webhooks, and app-review permissions. Follow the Messenger and Instagram setup guide.
  • Website bots require an exact allowed-origin list. Their embed snippet loads a sandboxed chat widget with no third-party token. Scheduled triggers and waits longer than five seconds are not supported on Website bots.
