ChatGPT & OpenAI Integration
OpenAI API and ChatGPT integration into your website, app, CRM or internal tools — with function calling, structured outputs and disciplined cost control.
What is ChatGPT & OpenAI Integration?
ChatGPT integration means connecting OpenAI's GPT models to your existing software through the API so they can read your data and take actions inside your systems, rather than staff copying text into a chat window. ADM Technology integrates the OpenAI API into websites, apps, CRMs and internal tools using function calling, JSON schema structured outputs, embeddings for semantic search and server-side key handling, typically shipping the first feature in three weeks and cutting token spend by around 50% through caching, batching and model routing.
Overview
Put GPT inside the software you run
You do not need a new product to use GPT, you need it wired properly into the software you already run. We integrate the OpenAI API into existing applications, CRMs and internal tools with function calling so it can act, JSON schema outputs so results are parseable, server-side key handling so credentials are never exposed, and caching and model routing so the bill stays predictable.

Exactly what we do, step by step
Every ChatGPT & OpenAI Integration engagement follows a clear, phased path — so you know precisely what work happens, in what order, and what comes out of each stage.
Integration Scoping & API Design
We identify where GPT genuinely helps inside your existing product or workflow, then design the API contract, prompt structure and expected output schema before writing any integration code.
Secure Gateway & Key Handling
We route every call through a server-side gateway so API keys never reach the browser, adding per-user quotas, abuse throttling and request logging to stop a leaked endpoint becoming a runaway bill.
Feature Build with Function Calling
We define the functions GPT can invoke against your systems and validate every response against a JSON schema, so the model triggers real actions in your CRM or database rather than merely describing them.
Embeddings & Semantic Search
We embed your documents, tickets and product data into a vector index so GPT answers from your own content with citations, which is what turns a generic assistant into one that knows your business.
Reliability & Cost Engineering
We add retries with exponential backoff, streaming, prompt caching, the batch API for non-urgent jobs and routing of simple calls to cheaper models, which typically halves token spend without hurting quality.
Launch, Monitor & Extend
We ship behind feature flags with per-feature token and latency dashboards, then tune prompts against real usage and extend the integration to the next workflow once the first proves itself.
