You can use the following GetTags endpoint to get the tags that a merchant has:
GET /v3/merchants/{mId}/tags

You can get a specific tag using the GetTag endpoint with the tag ID:
GET /v3/merchants/{mId}/tags/{tagId}

To get the items under a tag(s), you can expand the items field:
GET /v3/merchants/{mId}/tags?expand=items
GET /v3/merchants/{mId}/tags/{tagId}?expand=items

For getting tags from Android SDK, you can use the InventoryConnector:
https://clover.github.io/clover-android-sdk/com/cl...

You can then get the name from each tag using the getName() method from the Tag object:
https://clover.github.io/clover-android-sdk/com/cl...

Here is sample code:

for (Tag tag : mInventoryConnector.getTags()) {
                
    Log.d("TAG", tag.getName());
}

For getting the items under each tag, it currently looks like the Tag's getItems() method has a bug and returns null, I will file a ticket to have that fixed.

A workaround for now would be to use the InventoryConnector's getItems() method to get each item to retrieve the tags for each item, and build a mapping of items to each tag.
