how can we convert Appian document to base64 url

Question

requirement is to get all documents from particular folder and then send those document one by one to third party API, but problem is, this API accepts document as base64 URL, not Appian document id, so can someone suggest , how can we get base64 URL for Appian document such that, we can send the same to the third party API

Did you try just sending the document? I think it encodes it automatically. Is the issue that you need to put the base64 string in the URL instead of the request body?
