What is the business use-case for that? How that works?

There are some errors in this code. First one is like this: extractResponseTokens is not definedhttps://experienceleague.adobe.com/en/docs/target/using/administer/response-tokens#aep-badge-sending-data-to-google-analytics-via-platform-web-sdkCan somebody send this to people responsible for that docu...

Any ideas how to catch up such an event using RULES and push it to data layer / GA4 / whatever?

I hover over - its dark grey as you can see it .... Nothing showed up 

Do you know if there is a way to secure in some way that endpoint, some authentication or whatever?

If I were in you shoes I would start with AEP Business Practicioner. AJO is build on top of AEP so it would be much easier to understand core concepcts. Then AJO Business Pracitioner: https://certification.adobe.com/credential/verify/3ce6c9e3-bf61-11ef-8f8b-42010a40001c

Do you know also if you can have in the same time both AEP B2C and AEP B2B?

I have got multiple offers in my AP activity. When I would like to set up Targeting Audiences for a specific offer then I am able to do this only for a one offer. Same with Report Group. Why is that?  

Is it batch or streaming? Is there any workflow how to make that connection?

Is this possible to have both on one sandbox?
