Server Sending Invalid Match Key Parameters for Search Event #25

Closed aaronlax closed 2 years ago

"Your server is sending an invalid fbp, ip_address parameters value for your Search event. This may be because there was an error in the parameter value."

Not sure how to troubleshoot this, was reported by the site owner

Hi @aaronlax,

That error can be caused by differentent reasons, it can get difficult to find the exact reason.

That error can be triggered by bots or scripts. So, when it's not showing for all events, it can safely be ignored.
Can PHP read the correct IP Address of the user? If not, that can give a mismatch. E.g. the webserver is hosted by AWS or is beyond a load balancer.

Does that help?

The same issue!

Shouldn't be sent those event's parameters into the custom parameters? https://github.com/digitalwithyou/craft-facebook-conversion/blob/main/src/listeners/cms/Search.php#L14

Hi @mostafasoufi ,

Both the ip address and fbp are set by the official Facebook php library: https://github.com/facebook/facebook-php-business-sdk/blob/main/src/FacebookAds/Object/ServerSide/UserData.php#L874-L877

Facebook will not be able to identify all users. When there is no client side js library (e.g. blocked by an adblocker) and no Facebook query parameter and no emailaddress is set in the session, they won't be able to link the correct user.
