How to confirm Action offers via postback
Last updated
When you create an Action offer, conversions must be explicitly confirmed after the user completes the desired action on your website (e.g., signs up for a trial, makes a purchase, downloads a resource). This guide explains how to confirm Action conversions using a postback. How It Works
User clicks offer link
User is redirected to your website → You capture the tracking parameters
User completes the action -> Purchase/Signup/Download/etc..
You call the postback URL → Confirm the conversion with SparkLoop
Conversion is processed
When SparkLoop redirects users to your website, we append a submission query parameter to your redirect URL.
If your offer URL is https://example.com/signup, the user will be redirected to:
https://example.com/signup?submission=submission_1234abcd
Important: You must capture and store the submission parameter when the user lands on your site. You'll need it to confirm the conversion later.
Once the user completes your desired action, send a call to your unique postback URL.
GET https://api.sparkloop.app/v2/offers/postbacks/XXX?submission_uuid={submission_uuid}The postback URL is unique to your offer. You'll find your unique postback URL under your offer's "Conversion Pixel" instructions.
Replace {submission_uuid} with the submission parameter from Step 1.
Important Notes
Action conversions expire after 45 days if not confirmed
Make sure to confirm conversions as soon as the user completes your desired action
