Download Attachment From Outlook Using Graph Api Java

[Josephina Blincoe]

The next example uses the same request as in example 3 to get the properties of an item attachment on a message by using $expand. In this case, because the attached item also has a file attachment, the response includes the properties of the file attachment as well.


The response body includes the eventMessage attachment in MIME format. The body of the eventMessage is truncated for brevity. The full message body is returned from an actual call.

The OneDrive REST API is part of the Microsoft Graph API which allows our app to connect to content stored in OneDrive and SharePoint. We can work with files across the Office 365 ecosystem like OneDrive, OneDrive for Business, and SharePoint document libraries using graph API.


Java Mapping has been used to read the filename(with Invoice number) & file type from source payload, create target filename and to transform the attachment to main payload. Here is the snapshot of mapping.


It was a single call from ECC Proxy with payload & attachment to upload file as you see in the screenshot. OAuth is configured in channel so that the channel gets the token before making put/get request to OneDrive. No need of a separate call to get the OAuth token. Hope it is clear.


The "Northwind" example, is run via :play northwind-graph and contains an traditional retail-system with products, orders, customers, suppliers and employees.It walks you through the import of the data and incrementally complex queries using the available data.

If you thought that you could only embed charts with Zapier or Google Sheets, think again. Microsoft Excel is an excellent tool for this same purpose that allows you to embed and send charts in Excel via an email template. This way, you and other users can edit the Excel charts and graphs via email.



Using this method, you no longer need to resend a new file every time you make a change. You can do the same using a Microsoft Word document by embedding an updatable Excel chart or graph. This synchs your data and prevents you from having to make changes separately.


I am trying to export multiple datasets from a window of graphs and tables, but for starting out I am just trying for one. I have an export to excel button with actionPerformed script uploaded below. It creates an excel file but I get a sort of Null error popup, also uploaded. How do I get it to actually export the dataset?
