Table of Contents
Introduction

🎯 What This Guide Covers
This troubleshooting guide will help you:
- Understand the most common causes of postback failures
- Configure click session lifespans to prevent expiration issues
- Diagnose third-party service provider problems
- Monitor postback delivery through TUNE's reporting tools
- Implement preventative measures to minimize future failures
What Are Postbacks?
Postbacks (also called server-to-server tracking or S2S) are server-side notifications sent from TUNE to partners or third-party platforms when a conversion event occurs. They enable real-time tracking and attribution without relying on browser-based pixels.
Common Causes of Postback Failures
Postbacks may fail to be sent or received for a variety of reasons. Understanding these causes is the first step to resolving delivery issues.
⚠️ Primary Causes of Postback Failures
| Cause | Description | Impact |
|---|---|---|
| Expired Click Session Lifespans | If clicks expire before a conversion event occurs, postbacks will not be triggered because TUNE cannot attribute the conversion to the original click | Lost conversions, missing partner attribution, unpaid commissions |
| Cause | Description | Impact |
|---|---|---|
| Third-Party Service Provider Issues | Problems with services like ClickFlare, HasOffers integrations, or other postback processors that handle delivery or processing on their end | Delayed or failed postback delivery, data synchronization issues |
| Cause | Description | Impact |
|---|---|---|
| Incorrect Postback URL Configuration | Malformed URLs, incorrect parameters, or invalid endpoints prevent successful postback delivery | 100% postback failure for affected partners |
| Cause | Description | Impact |
|---|---|---|
| Partner Server Timeouts or Downtime | The partner's server is unreachable, slow to respond, or returns error codes (500, 503, etc.) | Temporary or permanent postback loss depending on retry settings |
| Cause | Description | Impact |
|---|---|---|
| Firewall or Security Restrictions | Partner servers block TUNE's IP addresses or reject postbacks due to security policies | Consistent postback failures until whitelist configuration is updated |
| Cause | Description | Impact |
|---|---|---|
| Network or DNS Issues | DNS resolution failures or network connectivity problems between TUNE and the postback destination | Intermittent or complete postback failure |
How to Ensure Postbacks Are Sent and Received Correctly
Follow these recommendations to minimize postback failures and maintain accurate tracking and partner payment:
1 Set the Click Session Lifespan Appropriately
Configure your click session lifespan within TUNE to cover the expected conversion window for your campaigns.
How to Configure Click Session Lifespan:
- Log in to your TUNE dashboard as an administrator
- Navigate to
- Locate the Click Session Lifespan setting
- Enter the appropriate duration based on your campaign conversion window
- Click Save to apply the changes
| Campaign Type | Recommended Lifespan | Rationale |
|---|---|---|
| Immediate Conversions (e.g., lead gen) | 7-14 days | Short sales cycle, conversions happen quickly |
| E-commerce (standard) | 30 days | Industry standard for most online retail |
| High-value B2B or SaaS | 60-90 days | Longer consideration and decision cycles |
| Financial services, insurance | 90-120 days | Extended evaluation periods common |
2 Communicate with Your Postback Service Provider
Promptly check with your third-party postback service provider to identify any outages, configuration issues, or required updates on their end.
Troubleshooting with Third-Party Providers:
- Contact your service provider's support team (e.g., ClickFlare, Voluum, RedTrack)
- Provide specific details:
- Date and time range when postbacks failed
- Affected conversion IDs or transaction IDs
- Partner IDs experiencing issues
- Any error messages or status codes received
- Request their server logs to identify the root cause
- Verify their service status page for any known outages
- Confirm postback URL configuration matches their current requirements
- API endpoint changes or deprecations
- Authentication token expiration
- Rate limiting or throttling
- Server maintenance or upgrades
- Changed IP address requirements
3 Monitor Postback Delivery Reports Regularly
Use TUNE's dashboard to identify and address postback failures early, before they impact partner relationships or payment accuracy.
How to Monitor Postback Delivery:
- Log in to your TUNE dashboard
- Navigate to
- Filter by date range to review recent postback activity
- Look for failed postbacks (indicated by error status codes)
- Click on individual postback records to view detailed error information
- Export failed postback data for further analysis if needed
- Postback Success Rate: % of postbacks successfully delivered
- Failed Postback Count: Number of postbacks that failed delivery
- Error Codes: HTTP status codes (400, 404, 500, 503, etc.)
- Response Times: How long partner servers take to acknowledge postbacks
- Partner-Specific Failure Rates: Which partners experience the most issues
4 Verify Postback URL Configuration
Ensure postback URLs are correctly formatted with all required parameters.
Configuration Checklist:
- Verify the postback URL begins with
http://orhttps:// - Confirm all required macros are included (e.g.,
{transaction_id},{payout}) - Test the URL format using TUNE's postback testing tool
- Ensure special characters are properly URL-encoded
- Check that the partner's endpoint is accessible from TUNE's servers
- Missing
https://protocol - Incorrect macro syntax (e.g.,
[transaction_id]instead of{transaction_id}) - Unencoded special characters in parameter values
- Typographical errors in domain names
5 Request IP Whitelisting from Partners
If partner servers have firewall restrictions, provide TUNE's IP addresses for whitelisting.
IP Whitelisting Process:
- Request TUNE's current postback IP ranges from TUNE Support
- Provide these IP addresses to your partners
- Confirm partners have added the IPs to their firewall allowlist
- Test postback delivery after whitelisting is complete
- Monitor for any future IP changes announced by TUNE
Monitoring and Prevention
🔍 Proactive Monitoring Best Practices
| Best Practice | Implementation |
|---|---|
| Set Up Automated Alerts | Configure email or dashboard alerts when postback failure rates exceed a threshold (e.g., 5% failure rate) |
| Daily Postback Report Review | Designate team members to review postback logs daily and flag anomalies |
| Partner Communication Protocol | Establish regular check-ins with high-value partners to ensure postback delivery is functioning properly |
| Documentation | Maintain a knowledge base of past postback issues and resolutions for faster troubleshooting |
| Quarterly Configuration Audits | Review click session lifespans, postback URLs, and partner configurations every quarter to ensure they remain optimal |
