How we can read the link data before loading the screen (especially company)?

SUGGESTED

Hi Folks, 

Can anyone please help me on below? 

In our customized process we prepare a suggested payment list (Bunch of “Invoice Authorised - Await Suggest” invoices)

and send it to the user(External User) for approval through the Sage X3 application.

An automated e-mail will be generated with the link from the system which includes the suggested number (a unique number for the suggested list) and company code into the link.

Users will use the same link to login to SAGE X3 (by clicking on the link in the email and putting their Microsoft login credentials). After login into Sage x3, it re-direct us to the suggested payment approval screen(Customized Screen).

We want to load the records as per the company passing into the link but it didn't catch the same company from a link and it takes a first legal company from the group of company list.

Kindly help us that how we can read the link data before loading the screen (especially company i.e 0ZUUK).

FYI - We have installed two Sage X3 applications and one of them is using for the external user (Microsoft authentication).
