Getting JS variable value in ABAP variable

hi experts,

I am fairly new to ABAP programming so please bear with me. To my issue.

I am creating a BSP which will read from the tax number table in CRM into an itab.

Next it loops into an wa and then passes each tax number through a javascript/JQuery API to validate the number.

The JSON response then comes back and is stored in a JS variable.

I am unclear how to get this into an ABAP variable so I can handle as needed. I have read some posts but they seem to be created for those ABAP experts which I am not there yet.

Any help is most appreciated.

thank you kindly!

Chris
