Today many websites have begun to offer far more than simply providing information. Users expect features that automatically write text, give smart answers to questions, or briefly summarize long documents. The fastest way to bring all of this to your site is to connect the API of a ready-made language model service such as ChatGPT or Claude. An API means a way for two programs to talk to each other, that is, your site sends a request to the model service over the internet and receives a finished answer from it. This approach completely frees you from the complex and expensive work of building or training a model yourself.
Many people consider such integration complicated, but in reality the process is quite understandable. The core idea is that the backend code hosted on your server connects to the model service using a secret key, forms the necessary request, and shows the returned answer to the user. Along this path, the things that demand the most attention are storing keys securely, organizing requests correctly, and placing the whole system on stable hosting. In this article we will walk through the entire process from beginning to end in an orderly way.
What an API key is and how to obtain it
To use a model service, you first need to create an account on that service's official site and generate a special key. This key is a string of long random characters that confirms your identity to the service. Each time your site sends a request to the model, this key is sent along with it, and the service knows who is making the request and whose account to bill. This is exactly why it is extremely important never to show the key to outsiders and never to store it in the open part of the site.
After obtaining the key, you usually add a certain amount of funds to your account or connect a payment method, because each request costs money depending on the volume of text processed. Many services provide beginner users with free trial credit, which lets you test your project without large expenses. Once you have the key, the next step is to embed it securely into your website's code.
Why the key must be stored only in the backend
A website can be imagined as consisting of two parts. The first part is the appearance visible in the user's browser, and the second is the hidden backend logic on the server. If you place the key in code that runs in the browser, any visitor can open the page source and freely see the key. This is as dangerous as leaving your house key under the door, because whoever finds it can use the model at your expense without limit and leave you with a large debt.
The correct solution is to route all model requests through the backend on the server. The user's browser only talks to your server, and the server in turn connects to the model service using the key. In this way the key never reaches the user's side and always remains in the server's secure environment. This approach not only protects the key but also gives you the ability to monitor and filter requests and apply the rules you need.
How the backend forms a request
When a user performs some action on the site, for example writing text and pressing a send button, the browser passes this data to your server. The backend code on the server receives this request and shapes it into a form the model understands. Additional instructions are usually added to the user's message, for example telling the model in what tone or in which language to reply. The backend then sends this prepared request along with the secret key to the model service and waits for an answer.
The model returns finished text within a few seconds, and the backend receives it, processes it if necessary, and then shows it to the user. This entire process unfolds invisibly to the user and very quickly. The backend code can be written in Python, PHP, or Node.js, and each of these languages has convenient tools for working with model services. The most important thing is that your hosting allows connections to the external internet and supports a modern version of the chosen language.
Handling errors and limits correctly
In real life not every request finishes successfully. Sometimes the network is temporarily unavailable, sometimes the model service is overloaded, or the number of requests exceeds a set limit. A well-built integration anticipates such situations and shows the user a clear message, preventing the entire site from failing. For example, if the answer is delayed, you can ask the user to wait a moment or add logic to retry the request.
It is also helpful to limit how many requests a single user can send in order to control costs. Otherwise someone could abuse your site by sending many requests and adding large expenses to your account. All of this is controlled in the backend logic, so a reliable and configurable hosting environment makes it easier to introduce such protective measures.
