Questions

Is this free?
Yes, completely free. There are no limits on the number of notifications.
Do I need to install a Slack app?
Just the free Incoming Webhooks app from the Slack Marketplace. Click "Add to Slack", pick a channel, and you'll get a Webhook URL — that's all you need.
Can I send notifications to multiple channels?
Yes. Create a separate Slack webhook for each channel, generate a separate endpoint here, and add each one in Expandi's webhook settings. For example: replies go to #sales-replies, connections go to #new-connections.
Which Expandi events can I get notified about?
All 27 Expandi webhook events are supported — replies, connections, messages sent, profile visits, email opens, and more. In Expandi, go to LinkedIn Settings → Webhooks to see the full list. Add one webhook per event type.
How fast are the notifications?
Near real-time. When Expandi fires the webhook, the notification appears in Slack within 1-2 seconds.
Is my data secure?
We don't store any of your data. The webhook payload flows through our relay server to your Slack channel and nothing is saved. Your Slack webhook URL is encoded in the endpoint URL itself — no database, no accounts, no data retention.
Can I use this for multiple LinkedIn accounts?
Yes. Each Expandi webhook is set up per LinkedIn account. You can generate one endpoint and use it across multiple accounts, or create separate endpoints per account pointing to different Slack channels.
