What exactly is a postback?
Think of it like this...
Imagine you're at a restaurant. When you finish your meal and pay, the waiter tells the kitchen "Table 5 just paid!"
A postback is exactly the same — it's a message that says "Hey! A customer just completed an action!"

The Complete Postback Journey
Follow the path from click to conversion
User Clicks
Someone clicks your affiliate link. This could be on social media, email, or your website.
Tracking Magic
The tracking server creates a unique fingerprint (like "99wijffo9") for this specific user journey.
User Converts
The user completes the goal — makes a purchase, signs up, installs an app, whatever you're tracking.
Postback Fires!
The landing page instantly sends a message back: "Hey! User 99wijffo9 just converted!"
Why postbacks are absolutely crucial
Fair Attribution
Without postbacks, you can't tell who deserves credit for a conversion. It's like having a sales team but never tracking who made which sale.
Real-Time Data
Postbacks fire instantly. The moment someone converts, all your tracking platforms know about it immediately.
Optimization
You can see which traffic sources, ads, and affiliates are actually driving results. This data powers your optimization decisions.
Real-world example
Let's say you're promoting a fitness app...
Your Instagram follower clicks your link
They see your story about the FitTracker app and tap the link in your bio.
Tracking server assigns ID: "insta_user_547"
Behind the scenes, your tracking platform creates a unique identifier for this specific user journey.
User downloads the app and subscribes
They love what they see and sign up for the $9.99/month premium plan.
Postback fires immediately
https://tracking.com/postback?user=insta_user_547&event=subscription&value=9.99¤cy=USD
Your tracking platform instantly knows: "The user from Instagram story just subscribed for $9.99!"
🎉 Result
You can now see that your Instagram promotion drove a $9.99 subscription. Your affiliate network credits you the commission. Your optimization data shows Instagram is working great!
Common beginner mistakes
"I can just track clicks, right?"
Clicks don't equal conversions! You need to know what happened AFTER the click. Did they buy something? Sign up? Install the app? Postbacks tell you the final result.
"Can't I just check manually?"
If you're sending hundreds or thousands of visitors, manual checking is impossible. Plus, you need real-time data to optimize your campaigns effectively.
"This sounds too technical for me"
Most affiliate networks and tracking platforms handle the technical setup for you. You just need to understand the concept so you can troubleshoot when things go wrong.
