Slack message on signup
Fires when a row is added to your signup table and posts a short message to the Slack channel you choose, through your connected Slack integration. Until Slack is connected in the builder the step is skipped, so it is safe to add before you connect.
What it adds to your app
One workflow: on signup, post to your Slack channel.
How its workflows run
Each one is a server workflow in your project: it runs on its trigger, with retries, and its runs show in the builder's log.
- Tell Slack about new ‹person› signups
When a row changes:
‹person› created. Then: Send channel message.
Set it up
It merges into the contract of an app you already have. Nothing is overwritten: a name you already use is refused until you pass a prefix.
- Pick the project
Use the button above, or ask your coding agent with the Appbricx MCP server connected (quickstart).
- Point it at your tables and roles
Leave out the ones with defaults; a wrong one is refused with the options your app has.
Param What it is Example personThe table a new person lands in when they sign up (usually named after the role). Optional. customerchannelThe id of the Slack channel to post in (in Slack: channel details, at the bottom, like C0123ABCD). C0123ABCD - Connect what it calls
connect Slack (builder, Backend, Integrations). Connect Slack in the builder's Integrations panel; until then the step is skipped.
- Preview, then apply to dev
A dry run shows the diff and the check report; applying it changes your dev environment only.
- Deploy
When dev looks right, deploy. Production gets a snapshot first, so you can roll back.
Use it with your coding agent
The agent reads the template, runs a dry run, shows you the diff and applies it.
Add the Slack message on signup template (slug "slack-on-signup") to my Appbricx project. Read it with get_template, run use_template with dry_run first and show me the diff, then apply it. Ask me where it attaches if you can't tell from my contract (person: who signs up; channel: slack channel id).{

Goes well with

Notifications
A notification centre for each person, with a bell for any page and email and text message preferences they control.

Welcome email
Emails every new person a short, friendly welcome the moment they sign up.

Slack when a status changes
Posts to a Slack channel when a row's status changes to the value you pick: an order shipped, a deal won, a ticket escalated.
