LLM Quick Start Guide

This guide provides an introduction to getting started with Large Language Models (LLMs) using
Cybersource
 documentation. Large Language Models have revolutionized how developers approach coding, documentation, and problem-solving. Using an LLM with
Cybersource
 documentation enables you to find the information you need without finding and reading a specific guide.

Getting Started

This section covers the fundamental concepts and initial setup required so that you can begin using LLMs effectively.
When you start working with LLMs, you must:
  • Understand model capabilities and limitations
  • Select the appropriate model for your use case
  • Set up proper authentication and API access
  • Implement best practices for engineering prompts

Best Practices

To maximize the effectiveness of LLMs in your workflow, follow these established best practices:
  1. Clear and specific prompts: Provide detailed context and specific instructions to get more accurate results.
  2. Iterative refinement: Use follow-up prompts to refine and improve the initial output.
  3. Validation and review: Always review and validate LLM-generated content before implementation.
  4. Security considerations: Never include sensitive information such as payment information and merchant credientials in prompts or queries.
  5. Version control: Track changes and maintain version history of LLM-assisted work.
Remember that LLMs are powerful tools that can augment human capabilities rather than replace human judgment and expertise.

Documentation Source

Technical documentation for
Cybersource
 is available in Markdown format. Markdown is easier for LLMs and AI agents to comprehend.
All documentation appears here: llms.txt
To access a specific guide for use in your LLM, change the
.html
 in a guide's URL to
.md
. For example, the Markdown version of applepay-getting-started.html can be found at applepay-getting-started.md.

AI Agent Toolkit

Cybersource
 provides an agent toolkit at agent-toolkit-intro.html. Use the agent toolkit to simplify the process of integrating
Cybersource
 APIs in your agentic workflows.
