Well, I did something similar to create a Firebase connector, I created my own inbound adapter and define a business services to use it, after that I configured the interval in the business service and that's all!

You can review the article that I wrote about it:

https://community.intersystems.com/post/connecting-intersystems-iris-and...

For your case the interval would be 86400 seconds to execute the inbound adapter task once each day.

If you have any doubt don't hesitate to ask me.

Yeah, probably is your best option.

Anyway, I think that you could add the pieces of the base64 field as values of the Base64EncodedFile list removing the (1) in my code:

Do stream.Rewind()
While (stream.AtEnd = 0) {
    // Not sure about the len
    Set len = 3641144
    do target.SetValueAt(stream.Read(.len), "LetterAttachment(1).Base64EncodedFile", "append")
}

The problem of this is that you couldn't include more documents attached because all the list would belong to just one document.

I was reviewing the documentation and I think that the only option available is to split your base64 by the MAXSTRING limit and append all the pieces that you get using SetValueAt defining the action as append:

method SetValueAt(pValue As %String, 
                  pPropertyPath As %String, 
                  pAction As %String = "set", 
                  pKey As %String = "") as %Status

It could be something like:

Do stream.Rewind()
While (stream.AtEnd = 0) {
    // Not sure about the len
    Set len = 3641144
    do target.SetValueAt(stream.Read(.len), "LetterAttachment(1).Base64EncodedFile(1)", "append")
}
