How do I attach an existing file to a Chatter post via the Chatter REST API?
Hello,
I would like to create a Chatter post via the Chatter REST API and include an existing file. To do this in APEX all you need to do is set the relatedRecordId field but I don't see how we can do this with Chatter REST.
I tried posting with attachment and an id but it doesn't work. Does anybody know what JSON needs to be included to include a file?
Thanks!
Kevin
Provide the "attachment" value as the JSON serialization of the "Attachment Input: Existing Content" input payload, as doc'd here: http://www.salesforce.com/us/developer/docs/chatterapi/Content/connect_resources_input.htm#cc_attach_existing_content
In JSON it should look like this:
{body: { ... body stuff },
attachment: { contentDocumentId: <enter id here>},
... }
