How to Integrate Campaignswell with Amplitude

Create a New Sync

Step 1. Open Amplitude Data

• Go to Amplitude Data > click Catalog
• Select the Destinations tab

Step 2. Choose Webhook

• Under the Event Streaming section, click Webhook

Step 3. Create Sync

• Enter any name for the sync (e.g., Campaignswell Sync)
• Click Create Sync

‍

Configure the Webhook

Step 4. Set Status

Choose Status: Enabled

Step 5. Add Webhook URL

Paste the Campaignswell-provided endpoint URL from Campaignswell UI

Step 6. Select Events

In Select & Filter Events, add the following events:

• all Amplitude events
• cw_subscribe (subscription start)
• cw_nrc_purchase (one-time/non-recurring purchase)

⚠️ If you use a funnel builder (FunnelFox, Web2Wave, etc.):The funnel builder sends its own events - they do not include cw_subscribe or cw_nrc_purchase. In this case, also add all relevant events from the funnel builder (e.g., ff_subscribe, ff_purchase, or however they're named in that tool). Specify which events correspond to subscription start and purchase in your funnel builder setup to your CSM.

Step 7. Enable User Data

Set Send Users: Disabled

Step 8. Save

Click Save to activate the webhook

Configure SDK Settings (Required for Web Attribution)

Step 9. Enable Page URL Enrichment & Attribution

To track web attribution properly, you need to enable attribution, pageUrlEnrichment, and sessions in your Amplitude Browser SDK configuration.

Add this to your Amplitude SDK initialization code:

amplitude.init(API_KEY, {
 autocapture: {
   attribution: true,        // ✅ Required for UTM tracking
   pageUrlEnrichment: true,  // ✅ Required for referrer & URL tracking
   sessions: true,           // ✅ Required for session_start events
 },
});

⚠️ The above is the minimum required for attribution. If you don't explicitly configure other autocapture options, Amplitude will automatically enable them (clicks, page views, form interactions, etc.) - this can quickly consume your plan's event limits. We recommend disabling any events you don't need.
