Oracle Integration Cloud (OIC) & octet-stream MIME-type by Amy Simpson-Grange


I was recently working on an integration in Oracle Integration Cloud (OIC) which leveraged REST APIs exposed from Oracle HCM. I needed to retrieve details from the REST endpoint in the image below. The overall solution would take this REST response and write the data to an XML file to be consumed by another system.

REST Endpoint

Response headers: Content-Type = application/octet-stream

As you can see in the REST response headers above, the content-type of the response is application/octet-stream. This response type has been supported by the Oracle Integration REST adapter for a couple of years now and is configurable in the trigger request and response allowing the possibility to both invoke REST integrations using binary content and return binary content in a REST response.

What is application/octet-stream MIME attachments?

Effectively, a MIME attachment with the content type “application/octet-stream” is a binary file. Usually, the MIME attachment is an application file or document that may be opened in specific applications. For example, a spreadsheet .xlsx file would open in Microsoft Excel, a .docx file would open in Microsoft Word or an .exe file would indicate a Windows or DOS executable program. However, the application/octet-stream MIME type is used for unknown binary files and is in fact the default binary file. File contents will be preserved in binary but it requires the processor to understand and determine the specific file type (e.g, from a filename extension).

Using application/octet-stream in OIC

This feature can be used by selecting the “Raw” option within the invoke Request/Response page when configuring the REST adapter. Read the complete article here.
