Calling IDM GET /stream - How to process in ION Desk?

unknown

Hi!

When calling /items/{pid}/resource/stream we get an octet-stream with the IDM document as a binary stream, this can be handled through a normal C# or Java code, just parse the stream and convert the stream to a Base64.

However, when running this API from ION Desk (Data Flow), I have a hard time understanding how I can call this API within a Data Flow node, and then receiving the Data in a Scripting node and converting that stream result into a Base64.

Is it possible to get an IDM payload in a Data Flow, and successfully parse in as a Base64 without having to include a 3rd party service?

Hello! I have run into this problem a couple times, and found the best solution is to use Python Scripting. Typically, my projects involve passing the API Get a BOD with values needed, and the API Trigger Scenario will "lose" the previous BOD and only return the Binary file, thus having a need to use the Merge activity with Advanced Scripting. This allows for two input parameters, one being the previous bod and the other being the binary file. Python can base64 encode the binary and create a BOD with parameter values previously attained. Below is a screenshot from a project where I used merge. 

This assumes you have CloudSuite InforOS. If you are on-prem, you could try dropping the file off to a File Share and then picking it up with a File Template BOD that will base64 the document. Problem here is that you wont have access to parameter values that define anything, like order numbers and such. If that is not needed, then that may work for you on-prem.
