how to pass Content Item Id to workflow through http post

[13Groszy]

Hi

I've got few content items which values need to be updated whenever Http post is made to the workflow.
I've managed to update the values but only if Content Item ID passed to 'Update Content Task' is hardcoded.

I'd like to pass Content Item ID dynamically with body/headers through Http post same as I pass value to change.
How can I archive that? Any tips? Unfortunately it has to be JavaScript expression so I can't pass direct values from Liquid.

Thanks

You should be able to POST to the workflow endpoint with data in the body and then parse the body via deserializeRequestData(). What I typically do is use a "Set Property Task" to deserialize the request data by setting the Value to deserializeRequestData(); . Then you have access to what was in the request body using something like property('YourPropertyName').ContentItemId in that "Content Item ID" field you show in your screenshot.
