Unless I misunderstand the use case, you can also convert the document into base64 (converts a file into a text string) and send the text string into a post API. Then you use a plugin to convert the base64 string back into a document in the process. I've done this before, and it works quite well, though you will also have to pass in the file name and file extension, as these metadata attributes are not retained in the base64 string.

You're correct, 19.3 is not yet available. Our projected GA release date is August 23rd. There is no plan to hotfix this new feature back to 19.2.

In the meantime, you could try Stewart's option for 19.2. In fact, you can actually use the an integration object to pull a document from another system.

Could you not break this into two stages:

POST a request to an Appian WebAPI to start a Process. Pass the process sufficient information in order to complete Step 2.
Use one of the plug-ins available in the AppMarket to pull the relevant document (e.g. SFTP Smart Services, Download Document from URL)

This functionality will available starting in Appian version 19.3. With 19.3, you can send a document as a binary request body to an Appian web API, and the web API can then start a process and pass the document in as a process variable.

with webAPI in appian we cannot send or receive documents, one workaround would be to receive the document as BASE64 string and convert it to document in appian
