Ballerina is a powerful, cloud-native programming language tailored specifically for integration scenarios. Its comprehensive support for modern network protocols and diverse data formats makes it an ideal platform for interacting with APIs such as OpenAI’s. By leveraging the OpenAI Connector for Ballerina, developers can simplify AI integration and access advanced features ranging from text generation to custom model management.

Capabilities of the Ballerina OpenAI Connector

The Ballerina OpenAI Connector serves as a bridge between applications and OpenAI’s robust REST API. It allows programmatic access to a range of cutting-edge AI features, including:

• Text Generation Automation: Enable content creation, chatbot dialogues, and automated responses using endpoints like /chat/completions or /responses.
• Audio Processing: Transcribe or translate audio files through /audio/transcriptions and /audio/translations, unlocking possibilities for multilingual support and audio analysis.
• Image Generation & Editing: Create original visuals or alter existing images with /images/generations and /images/edits, ideal for marketing, content creation, or design tools.
• Fine-Tuning Models: Manage and deploy custom machine learning models via /fine_tuning/jobs, perfect for highly specialized AI solutions.
• Vector Store Management: Organize and search large datasets with /vector_stores endpoints, supporting semantic search and recommender systems.
• Analytics & Moderation: Analyze content safety and monitor API usage using /moderations and /organisation/usage tools.

Getting Started: Prerequisites

Before proceeding, ensure the following prerequisites are met:

• Ballerina Installation: Download and install Ballerina from the official website.
• OpenAI Developer Account: Sign up on the OpenAI Platform and receive access credentials.

An OpenAI API key (token) is required for authentication and API requests.

Step-By-Step: Setting Up OpenAI Access

1. Create a Project on the OpenAI Platform

• Open the OpenAI Platform dashboard.
• Access the user profile menu at the top right.
• Choose “Your Profile.”
• Navigate to “Projects” on the sidebar and click “Create Project.”

2. Generate and Secure Your API Key

• Enter the “API Keys” section.
• Click “Create new secret key.”
• Assign a name (e.g., “Connector Key”) and select the related project.
• Copy and securely store the generated API key (it will not be displayed again).

Quickstart Guide: Integrate the OpenAI Connector in Ballerina

Prerequisites

• Have a Ballerina project ready. Refer to the official documentation to set up a new project.

1. Add Credentials

In the Config.toml file of the project, insert your API token:

text

token = "<Your_Access_Token>"

2. Import the OpenAI Module

Insert the following import statement into your .bal source code:

text

import ballerinax/openai;

3. Initialize the OpenAI Connector

Set up the connector client with your token:

text

configurable string token = ?;
final openai:Client aiClient = check new({
  auth: {
    token
  }
});

4. Use the Connector for AI Operations

With initialization complete, invoke OpenAI APIs as needed. For example, to generate a chat completion:

text

public function main() returns error? {
    io:println("Enter a topic or keyword:");
    string userPrompt = io:readln();
    string systemPrompt = "You are a skilled marketing assistant. Create an engaging social media post based on the topic.";
    openai:CreateChatCompletionRequest request = {
        model: "gpt-4o",
        messages: [
            { role: "system", content: systemPrompt },
            { role: "user", content: userPrompt }
        ],
        max_tokens: 100,
        temperature: 0.9
    };
    openai:CreateChatCompletionResponse response = check aiClient->/chat/completions.post(request);
    io:println("Generated Social Media Post:");
    io:println(response.choices[0].message.content);
}

5. Run the Application

Execute the application with:

text

bal run

This launches the OpenAI client, sends a text generation request, and displays the AI-generated output.
