Is it possible to create relationship classes in AGOL without using Arcgis Pro? How does someone do this if they don't have a pro license for example?
I realise it's possible to use the analysis tool to create a hosted join layer but it's not quite the same and you end up with a separate feature layer for each join.
Not that I can see. Hopefully it's on the road map.
I think it was an Idea but you could vote for it here. I tried searching and it did not come up.
You can do it by adding to the definition . You need to build the relationship in json and the layer you want to add to the feature service and add it to your feature service definition. I have done it before but you need to be careful as it's not a supported workflow . I have a document describing it in more detail I ll share it with you next time i am at my desktop. Some links below as well
That would be great thanks. I found this article which mentions the ability to add or delete relationships through the REST API but it says that's it's not recommended.
