Learn how to utilize Everflow's Postback Testing Tool to verify the proper firing and data transmission of partner postbacks, ensuring accurate integration before campaign launch.

Overview

The Postback Testing Tool in Everflow helps you confirm that your Partner’s postback is firing correctly and includes the right data. This ensures your integrations are properly set up before launching traffic.

Heads up This tool cannot test HTML pixels. To test HTML pixels, you'll need to trigger a real conversion on the Offer’s landing page.

Step-by-Step Guide: Testing a Partner Postback

Access the Postback Test Tool

Navigate to Partners -> Postbacks

Locate the postback you want to test

Click the three vertical dots

and select Test

Pro Tip:

If there are multiple postbacks (e.g. global + specific), all will fire during the test.

Select Your Tracking Method

2A. If using traditional redirect tracking (not direct linking):

Ask your Partner for their test tracking link

Toggle ON: Use tracking link provided by the partner

Paste their test link into the field

2B. If using direct linking + Everflow JS SDK:

Toggle OFF: Use tracking link provided by the partner

Open your Partner’s test link

Use a redirect tracking tool (e.g. browser plugin) to:

Identify which parameter is carrying their click ID (e.g. sub1, source_id)

Copy that value and paste it into the correct parameter field

Run the Test

Click Test to simulate the click and conversion.

Everflow will:

Fire the Partner’s base and event postbacks

Record the test as a conversion with the note: “Everflow Test Postback Tool” in adv5

Review the Test Results

Once complete, you’ll see a success message with the generated:

Transaction ID

Conversion ID

Click either ID to view full conversion details.

Troubleshooting Common Issues

❌ Error: Could not generate click

Check these settings:

✅ The test link matches the Offer where the postback / pixel is placed (if Postback Level = “specific”)
✅ Your Partner is passing their unique click ID via the their partner tracking link
❌ The Offer doesn’t have any of the following enabled:

Duplicate Click Filter
Forwarding Rules
Fail Traffic
Proxy Blocking
Partner provides a test link from a Smart Link

❌ Error: Postback did not validate

Ensure:

✅ The postback is correctly formatted to return the Partner’s click ID back to their 3rd party platform.

Example: If Partner sends the click ID using sub2=, your postback should use {sub2}:
- Tracking Link: https://yourdomain.com/offer/?sub2=CLICKID
- Postback: https://partnerpostback.com/?click_id={sub2}

❌ None of the following are enabled:
