How to connect Slack

A step-by-step guide to generating a Slack Incoming Webhook URL to get notified when guests RSVP.

Connecting Slack to Invitly

Want a real-time feed of RSVPs dropping in? Connect Invitly to a Slack channel using an Incoming Webhook.

Step 1: Create a Slack App

  1. Go to the Slack API Dashboard and log in.
  2. Click Create New App.
  3. Choose From scratch.
  4. Name your app (e.g., "Invitly RSVP Bot") and select the workspace where you want it installed.
  5. Click Create App.

Step 2: Enable Incoming Webhooks

  1. On the Basic Information page for your new app, click Incoming Webhooks.
  2. Toggle the switch to On.

Step 3: Create a Webhook URL

  1. Scroll down to the Webhook URLs for Your Workspace section.
  2. Click Add New Webhook to Workspace.
  3. A screen will prompt you to choose a channel (e.g., #events-rsvps). Select it and click Allow.
  4. You will be redirected back to the app settings. You will now see a new Webhook URL in the list.
  5. Click Copy next to the URL. (It will look something like https://hooks.slack.com/services/T000...)

Step 4: Save in Invitly

  1. Go to your Invitly dashboard.
  2. Navigate to Integrations.
  3. Paste the Webhook URL into the Slack field.
  4. Click Save.

That's it! When you enable RSVPs for an event, new registrations will automatically be posted to your selected Slack channel.
