Error on parameters sent to MPGS URL

Hi Ali,

I’m having an issue passing parameters to the URL specified by my bank; here’s the error: https://bit.ly/3laCIGh

The URL format is: https://bit.ly/2TS7jMD

If this provided documentation by my bank will help- https://tinyurl.com/y3wwesvs

Perhaps other integrations have a similar case with mine here in the MENA region; therefore your help is truly appreciated.
