My self-hosted affiliate tracking script is messing up conversion tracking data after recent update!

Hello Isabella Johnson, I've definitely been there, staring at a dashboard full of zeros when you know good and well sales are rolling in. It's enough to make you pull your hair out, isn't it? Even the most "trusty" (and sometimes "untrusty," post-update!) `affiliate tracking script` can throw a curveball. The log you've provided is pretty clear: your script is *receiving* `0.00` as the conversion amount, not failing to calculate it itself. This is a classic headache in `affiliate marketing` and usually points to an issue upstream. Here’s where I'd start digging to get your `conversion optimization` back on track:

• Check Your Server Postback/Webhook Configuration: The most common cause is that the system sending the conversion data (your e-commerce platform, CRM, payment gateway, etc.) is either sending `0.00` explicitly, or it's failing to retrieve the actual amount before sending the postback. Verify the URL and parameters configured in the *source* system. Ensure the variable holding the transaction amount is correctly populated and passed.
• Review API Integration/Connectors: If you're using an API, double-check the payload structure. The update to your tracking script might expect a different data type or field name, causing it to default to zero if the expected value isn't found or is invalid.
• Examine Data Type Mismatch: Ensure the amount is being sent as a numerical value (float or integer) and not a string that's then misinterpreted. Sometimes a minor change in how a number is formatted (e.g., including currency symbols, or using a comma instead of a decimal point) can cause parsing issues.
• Script Update Changelog: Did the script update include any breaking changes regarding postback parameters or expected data formats? Review the changelog and documentation for your specific script version.
• Debug the Sending Side: Use network monitoring tools or check the logs of the *system sending* the conversion data to see exactly what amount is being included in the request *before* it even hits your tracking script. This will confirm if the `0.00` originates there.

Hope this helps get your conversions back on track!

Ah, got it! That was exactly it, thanks for pointing me towards the sending side. Turns out the e-commerce platform updated its API and changed the parameter name for the amount without telling anyone, leading to all the zeros.

Now the amounts are coming through correctly, which is a huge relief, but I'm seeing a weird discrepancy where the *total* daily commissions in the script don't quite match what I'm calculating manually. It's usually off by a small percentage, like 2-3% for the overall daily total, not individual transactions.
