Summary

The OpenAI Adapter in Oracle Integration Cloud (OIC), initially perceived for chat interactions, offers native operations for advanced file processing. A proof of concept, detailed in this article, demonstrates its capability to upload and process various document types, including JPG, PNG, PDF, and Microsoft Word files, without custom REST integrations. By separating the solution into two OIC integrations—one for uploading files and obtaining a reusable File ID, and another for processing that File ID with a prompt—the adapter can extract structured JSON responses. This method successfully analyzed multilingual content, such as Arabic and Persian invoices and multi-page PDF documents, using the gpt-4.1 model with Temperature = 0. This approach enables use cases like invoice extraction and content structuring directly within OIC.

Key takeaway

For AI Engineers or Integration Developers working with Oracle Integration Cloud, if you are considering document processing or data extraction, you should explore the native OpenAI Adapter. This allows you to process images, PDFs, and Word documents into structured JSON without custom API calls. You can significantly reduce manual data entry and simplify document-driven workflows by leveraging its file upload and response operations.

Key insights

The OpenAI Adapter in OIC natively processes diverse files into structured data using a reusable File ID.

Principles

• Upload files once, reuse File IDs for multiple analyses.
• Parameterize integrations for broad reusability.
• Clean file names prevent upload errors.

Method

Upload a file to OpenAI via OIC to get a File ID, then use that ID with a prompt in a separate OIC integration to process the document and receive structured JSON.

In practice

• Extract invoice data from images or PDFs.
• Digitize and structure multilingual legacy documents.
• Index content for search and retrieval solutions.
