I have tried the same, but we are receiving 500 internal server error. What is the content type you are passing is it "Json" or "Document Auto detect" ?

I used todocument() function to achieve it. Pass the document id as parameter to this function and rest appian will take care

If your last sentence refers to the documentation posted above, then yes.

This is a sample of the code how it will look like and how i have implemented

{

"name":"Document_name",

"document":todocument(documentID)
}

So Stefan, you are saying that if we use base64 encoding in appian, it will give us the base64 string and we dont need to worry much about it. It will just pass it as the string to the external system

As explained in the documentation, Appian will take care of the base64 encoding automatically if done as described. Do you want to share your current configuration?

I think you should use encodebase64string() function to achieve your requirement, may it is useful.

I tried using 1st method, we had error like file too complex from the integration response. So not sure if this is the way to do it.
its saying to use todocument() which is returning the document name. The external system needs the document in base64 string.

the base64 string should look something like this : "VGVzdCBkb2N1bWVudCA3ODM0dGhxaXJ1aXJnaFdSTEdKUVJPR0hBRVJWQU5HT0xRUkhHT0xRUkdKSU9HSFFLQU5SU0dPcXczNWhnb2h3cmthdnJpb2d1cWdqYWhma3JnS0ZVR0hL"

Will this be taken care if we use todocument inline with json??
