Facebook errors

We all know how difficult it may be to deal with the errors inside your Facebook account instead of running campaigns and earning money. Here we have collected the most common errors and provided our advice on the fix.

1. Missing Purchase Currency and Value Parameters

“One or more of your Purchase events is missing a value and currency parameter. This may affect your return on ad spend calculation.”

If you have the value optimization on, some conversions do not get the value still. We always send the currency and value by default. This issue can be observed with test conversions. So it’s essential to send all values during the test (add it to the fired test postback)

2. Purchase Event Missing Deduplication Parameter

Most probably, you are using Conversion API and pixel at the same time.  In this case, you will see both server and pixel type under the event in your Facebook account.
Use only the Conversion API or pixel to solve the issue.

Another reason can be a duplicate from a pixel or Conversion API without any unique event value, Facebook can recognize.

What can be done? Go to event view details -> event deduplication -> check what events were deduplicated and what information is available. This information will become available no earlier than several hours after you see the error itself.

3. Event match quality is low

If you work with an affiliate offer, it’s impossible to have 10/10 match quality. There is a list of the parameters Facebook wants to receive, but only half of them can be covered by a third-party tool.

This causes the match quality low level. And it’s not something you should struggle with.

However, we are working on sending as many parameters as it is possible to make this parameter value higher.

4. Conversion attribution differ

Conversion attribution may differ due to the FB algorithms (for example, they can be sent to different adsets if Facebook considers attributing some particular conversion to another adset)

If the conversion is older than seven days, FB can exclude it from your statistics.

5. Purchase Events May Be Dropped Due to Missing Event Source URL Parameter

Ensure you have followed the Facebook integration guide, verified your domain, and added it to your RedTrack offer settings.

6. Conversion window

Facebook has 7 day attribution window. If there will be less then 7 days between click and conversion – Facebook will attribute it.
