Calling Document Extraction API from Integration Suite

[ildar_dlw]

Hi All,

We are trying to develop the interface in the Integration Suite, which at some moment sends a document for the Document Information Extraction service via the following API:

https://xxx.cfapps.xx.hana.ondemand.com/document-information-extraction/v1/document/jobs

One of the technical difficulties is the fact that Integration Suite doesn't fully support formdata requests.

After some attempts the following response is received:

{"error": {"code": "E30", "message": "Cannot process file of content type.", "details": [{"code": "0", "message": "Content type: None"}]}}

Request has a Content-Type header with the value:

multipart/form-data; boundary=--cpi

Could you please share some experience or tips and tricks to use of the API from the Integration Suite? Or if you have success stories, would be happy to hear that.

Thanks a lot!

You need to implement the multi-part upload with custom code. There, is also a content package which contains such implementation. This can be used as starting point. Content: https://api.sap.com/package/SAPAIBusinessServiceDocumentInformationExtraction/integrationflow
