Google Document AI - Node

I am trying to get the Google Document AI Working on a HTTP Request node:

I tried a long time but did not manage to feed binary any data into a HTTP Request node with the endpoint format:

I know there is already a Google Cloud Natural Language API but that is only translating a document content into natural language.

I am searching for a solution to get a Invoice PDF Document in binary data from a cloud storage like for instance Nextcloud and then feed it to a Google Document API to extract relevant and categorized data?

Did anyone already manage that on n8n? I guess a Google Document AI Node would be a nice thing also.

Hi @prononext, I am sorry to hear you’re having trouble.

The link appears to be broken for me, any chance you can post a link leading directly to the reference for the endpoint you’re trying to use?
