Attach file in D365 FO using JSON based custom service

(0) ShareShare
ReportReport
Posted on by Daniyal Kashif 49

Hi, 
I've created a JSON custom service that is consumed by a mobile application. The service attaches a document to the record in D365. Currently the file is passed as base64 encoded string. Due to large file size, the encoded string is very large and this slows down the process. 

Is there any alternative to this approach?

Is there a way to pass the file as stream in the service parameters?

Thanks

    I successfully built a proof of concept of a service accepting a data stream, but it was a SOAP service in AX 2012. I've never tried it with a JSON endpoint in F&O - but you can easily give it a try.

    You surely can think about alternatives, such as uploading the file to a blob storage, passing a link through the web service and letting F&O to download the file from there.

    But if the file is large, it'll always take some time. If "this slows down the process" means that user interaction is blocked until the upload it complete, consider doing the whole thing asynchronously in background.
