Is It possible to call a webservice after an asset is uploaded with all metadata?

Question

Hi community,
 
I'd like to know if it is possible to call a webservice after an asset is uploaded to a folder with all metadata as payload.
 
Thanks in advance for your help.

@olsalas711  There are multiple options:1. Custom workflow is triggered by dam-authors manually, once the asset is ready.2. If an asset is published once its ready, then a custom Transport handler can publish the asset info to webservice, while publishing the asset in parallel to AEM publish. https://www.dev-eth0.de/2017/01/08/aem_transport_handler/3. Create an additional metadata, to define the state of an asset (ready/not-ready). Once all metadata is in, update the value of this metadata to ready. This event can then be captured and info can be sent out to webservice.

Consider, writing a Custom Workflow with a Process step, which calls the required webservice with Asset as payload. Metadata can be extracted in custom Process before calling the WebService.

Workflow can be triggered with a Workflow Launcher, set for the folder path and EventType as Node Created and NodeType as dam:Asset.
Launcher can also be written to trigger a workflow, based on any metadata property.
Refer below link for extracting Asset metadata:
