Hello @Balaram7 ,

List collector give value like val1,val2,val3 in comma separated string , and you have to check whether each branch is trusted or not  so you can first convert string value into array format using stringVariable.split(',') method and then send each value in your glideAjax using for loop  then you can get your required response true or false , once get true then break the for loop and update that trusted partner checkbox as true .

You can refer code suggested by @Tanushree Maiti   but just  break the loop once response get true .

If this helps you then mark it as helpful and accept as solution.

Regards,

Aditya
