Introduction

Building with Large Language Models (LLMs) can significantly accelerate your OpenPhone API integration development. This guide will help you effectively use LLMs to create applications with our API.

While we provide examples using Claude, the principles and practices outlined here apply to any capable LLM platform.

Getting started

Documentation setup

Before beginning development with an LLM, gather and prepare the necessary documentation:

1

Download OpenAPI specification

Get our OpenAPI specification for detailed endpoint information.

Tip: Right-click and select “Save Link As…” to download the file

2

Get complete documentation

Download and extract our complete documentation package

3

Share with your LLM

Provide these resources to your LLM to help it understand OpenPhone API capabilities

Development process

Working with LLMs

Clear goals

Start by clearly describing your integration objectives to the LLM

Documentation

Share relevant API documentation and specifications

Step breakdown

Let the LLM help break complex features into manageable tasks

Iterative development

Generate and review code one step at a time

Best practices

Example interactions

Here’s a practical example of how to instruct an LLM to help build with our API:

Integration patterns

Message automation

Automate message handling and responses

Contact management

Sync and manage contact information

Call analytics

Process call summaries and recording data

Scheduling

Manage scheduling and reminders

Implementation checklist

1

Code review

Thoroughly review all LLM-generated code

2

Testing

Test extensively in a development environment

3

Error handling

Implement comprehensive error handling and logging

4

Monitoring

Deploy with appropriate monitoring systems

5

Iteration

Continuously improve based on usage and feedback
