EE4 gateway – change processing url for ProCharge

I need to know how to change the processing url inside of EEG_Aim.gateway.php without hacking the EE4 plugin. My version is 4.9.31.p

All i need to do is change this “”
to “”, see instructions here:

I found the funtion possibly_use_deprecated_aim_server() inside /event_espresso/caffeinated/payment_methods/Aim/EEG_Aim.gateway.php

Looks like I could hack the plugin here. But I would rather use a hook and do it the right way. Better yet, create a functionality plugin to work alongside EE4.


First, would you add this functionality into the next version of EE?
Second – if not, what is the best way to hook into that function?

Thank you kindly!

Hi Matt,

There is already a filter available within the AIM payment method, possibly_use_deprecated_aim_server() uses that filter and its actually within the first method in the screenshot you posted:


Add your own function that uses that same hook to change the URL to whatever you prefer, just make sure it hooks in later than possibly_use_deprecated_aim_server() does, id use priority 20.

For example:

Add that functions to Custom Functions Plugin to set the URL to the one you requested.

Tony, thankyou. This helps.
One more thing – do you know how I can find out if the code is working? Is there an EE4 object I can print_r to view gateway url? (I’m guessing not). But im just wondering if there is a way other than when we get into testing.

Yes, you can view the payment logs within:

Event Espresso -> Payment methods -> logs.

When you attempt a payment you will create log entries there (likely at least 3 for AIM) if you view those logs you can see which URL is being used there within the ‘Server URL’ field.
