What it means: Everflow couldn't record the initial click needed to trigger a test conversion.

Check these settings on the Offer:

✅ Duplicate Click Filter — Disable temporarily for testing (Settings → Traffic Filters)

✅ Proxy Blocking — Your VPN or company network may be flagged as a proxy

✅ Forwarding Rules — If enabled, traffic may be redirected away from the test Offer

✅ Fail Traffic — Check if this is enabled and blocking clicks

✅ Smart Link Test — The test tool doesn't support Smart Link IDs; test individual Offers instead

Related Error Codes:

• Code 21 — Duplicate Click (same user clicked recently)
• Code 23 — Proxy Block (IP flagged as proxy/VPN)
• Code 1018 — Anura Fraud Check rejection

What it means: The click was recorded, but the postback itself failed validation.

Check these settings:

✅ Parameter Mapping — Ensure the Partner's click ID parameter matches your postback macro
Example: If Partner sends sub2=CLICKID, your postback must use {sub2}

✅ Min Click-to-Conversion Time — Disable or set to 0 seconds during testing

✅ Verification Token — If enabled, ensure the token in your postback matches the Advertiser's settings

✅ Anti-Fraud Tools — Temporarily disable Anura or similar integrations for testing

Related Error Codes:

• Code 12 — Invalid Transaction ID (ID not found or expired)
• Code 21 — Invalid Verification Token
• Code 26 — Postback Control rejection

What it means: Everflow fired the postback successfully, but the Partner's system didn't record it.

Troubleshooting steps:

✅ Check Partner Postback Report — Go to Reporting → Partner Postback to see the response code

✅ Response Code 200 — Partner received it; issue is on their end

✅ Response Code 4xx/5xx — Partner's endpoint is rejecting or erroring

✅ Use Debug Info — Click the ⋮ menu on any row and select "View Debug Info" to see full request/response

Common Partner-Side Issues:

• Partner's server is blocking Everflow IPs (share our Server IP list)
• Partner expects POST but Everflow sends GET (most postbacks are GET)
• Parameter name mismatch (they expect "clickid" but you're sending "click_id")

What it means: Your browser is blocking the test tool's popup window.

Quick fixes:

✅ Allow Pop-ups — Click the blocked popup icon in your browser's address bar and allow for Everflow

✅ Disable Ad-blocker — Extensions like AdBlock or uBlock can interfere with the test script

✅ Turn off VPN — Some VPNs block JavaScript execution or modify requests

✅ Try Incognito/Private Mode — Opens a clean browser session without extensions

✅ Check Firewall — Corporate firewalls may block .js files from loading

What it means: The conversion was recorded but credited to a different Partner than expected.

Common causes:

✅ Email Attribution — If you reused the same test email, a previous Partner may have "claimed" that email
Fix: Use a unique email for each test (e.g., test+partner1@example.com)

✅ Cookie from Previous Test — Clear your browser cookies between tests or use Incognito mode

✅ Lead-First Requirement — For integrations using Email Attribution (Zoho, Stripe), the lead event must fire before the conversion
