I have the following scenario:
Website A contains product description and links to the booking website B where the user places his order.
I need to track conversions placed on the website B and have them displayed in the Google Analytics account of the website A (which I controll). Website A is owned by me, website B is a 3rd party website but I can have their webmaster insert tags in their GTM.
Both websites use GTM for analytics tracking code.
So far I have cross domain tracking setup.
Website A has following setup: Cookie-Domain: auto allowLinker: true autoLinkDomains contains domain of the website B
Website B has following setup: Cookie-Domain: auto allowLinker: true autoLinkDomains contains domain of the website A
In GA account of the website A I have added the domain of the website B to the referral exclusion list.
So far good, the links on the website A are being decorated with the linker parameters so the website be receives the client ID.
Now comes the problem part: I didn't find any explanation of how I should now report the conversions which are done on the website B to the google Analytics account of the Website A. I only want to report the conversions for which the Website A accounts because the Website B has many other traffic sources!
How can this be achieved? As said I can have webmaster of the website B to configure their GTM tags accordingly when I know what to configure there.
