8 years ago Maybe we can add inside the alfrescoContent api a system that call the renditions api:
POST /nodes/{nodeId}/renditions
when one of thumbnail link return 404 in order to ask to regenerate it

8 years ago From the conversation with @ohej we can:
For multipart/form-data upload you can use the renditions field to create renditions (e.g. doclib) asynchronously upon upload. Note that currently only one rendition can be requested. Also, as requesting rendition is a background process, any rendition failure (e.g. No transformer is currently available) will not fail the whole upload and has the potential to silently fail.
the parameter is parsed here
Due a problem in the RestApi the thumbnail could be not generated during the upload:
https://github.com/Alfresco/community-edition/blob/master/projects/remote-api/source/java/org/alfresco/rest/api/impl/NodesImpl.java#L2610
When this problem occurs , the thumbnails have to be asked with the parameter c=queue in order to be regenerated.Something like :
http://127.0.0.1:8080/share/proxy/alfresco/api/node/workspace/SpacesStore/ac1c98aa-67de-417f-af81-5ada42e16d60/content/thumbnails/doclib?c=queue&ph=true&lastModified=doclib:1471021625609
More details can be found also in this discussion in the forum:

With this parameter probably the thumbnails are regenerated every time ( this is the approach used in Share ).
https://github.com/Alfresco/community-edition/blob/master/projects/remote-api/source/java/org/alfresco/repo/web/scripts/quickshare/QuickShareThumbnailContentGet.java#L115
Despite the fact that this approach regenerate the thumbnail you need to reload it at least once in order to display it.
