Hi all,
I am trying to use the AEM Assets HTTP API (Assets HTTP API ) but having some problems with it.
I'm testing some things using postman. When doing:
POST /api/assets/myFolder/myAsset.png -H
"Content-Type: image/png"
--data-binary
"@myPicture.png"
I get a 201 response back and the asset is created BUT there is no thumbnail. Do I need to do anything extra for this? Can I check somewhere for errors (although the HTTP response is OK)
Second problem. When trying to update the metadata of the Asset:
PUT /api/assets/myfolder/myAsset.png -H
"Content-Type: application/json"
-d
'{"class":"asset", "properties":{"dc:title":"My Asset"}}'
This also gives back an OK response but the property isn't updated.
Anyone here who has experience using this in AEM 6.3? Any suggestions?
Solved! Go to Solution.
I took a look at this API - its a limited restful API. For example - to create a folder - use this CURL command --
curl -u admin:admin POST http://localhost:4502/content/dam/myFolder -H"Content-Type: application/json" -d '{"class":"assetFolder","properties":{"title":"My Folder"}}'
However - i do not think you will get full access to Assets functionality that you will by using the Java AssetManager API.

If you want to hit an AEM endpoint - you should look at writing a SLing Servlet and use the AssetManager API. You will have much better control and the Java API offers better functionality.

I understand what you mean when regarding to more control. But can't I just use the APi's at hand? There is an Asset API which is enough for what I want to do.
Maybe someone here has used it before?

I would look at using the AssetManager API within a Servlet to modify Assets. See this article where we show using AssetManager API from within a Servlet.
Using the AssetManager API - you get the renditions, etc - as shown in this article.

Thank you all for the responses. However, I find it strange that there is (although limited) documented Assets API which seems to not be working.
I know I can get a lot more functionality using the java API but then why is there an HTTP api?

Thank you all again for the help.
I started with the tutorial on making a custom endpoint to create assets. However I'm getting these errors while building (mvn clean install)

I know I'm a bit late to the party here, but I just figured this out. When attempting to edit metadata you'll need to edit the metadata object that the properties object contains. e.g. "properties":{ "metadata":{"myVar":"Val"} }. So your request body would actually need to be "properties":{"metadata":{"dc:title":"My Asset"}}. This is assuming that the property you created in the metadata scheme is mapped to something like ./jcr:content/metadata/myProperty
