Do you connect external tools in order to monitor Observability API?Do you have any tools to recommend?How you do that?

This might be some work around:https://experienceleague.adobe.com/en/docs/experience-manager-assets-essentials/help/bulk-import-assets-view#schedule-imports

Is there any way to upload content to Assets Essentials? Img's etc?I see that you can only upload content fragment: https://developer.adobe.com/journey-optimizer-apis/references/content/#operation/createFragment

@jayakrishnaaparthasarathy thanks! What do you think about export job to dataset, then exporting dataset?

My customer is considering AEP but without AJO.I do not know any specific API endpoint which would work like that:1. Request with specific Audience ID2. Emails which belongs to that audience are returned and then 3. 3rd party tool can make a email campaign  Workaround 1:1. I create export job2. Expo...

Customer has to buy add-on in order to have Customer AI & Look alike audiences?These are bought in packages as explained below? https://helpx.adobe.com/legal/product-descriptions/real-time-customer-data-platform-b2c-edition-prime-and-ultimate-packages.html

It seems interesting... have not used that yet

Assume that my customer has 20 products (FSI Industry). Have you ever done such a use-case - rendering last seen product/service in email using only AJO (not Target)?

Dynamic on the fly - you mean requested by Actions on the fly using API? No - rather static. Rather something simple - QR in email for the customer to easily download bank mobile app. 

Has anybody done such a use-case?I assume that image should come as an import to AEP and then render such a QR code in AJO template?
