Do you want to find out more about chatbots and how to create effective bots for your site? Check out these articles:

Let’s start by clarifying that a chatbot is a computer software that can simulate a conversation with a human by sending automated messages in accordance with the user’s intent. Chatbots are widely used by companies to provide automated customer service.

But—

What is a chatbot API?

Chatbot API is a collection of documents that allow users to connect their channels with chatbot software and add more functionality to the chatbot. It allows you to integrate the chatbot with your website, social media channels, and other messaging platforms. 

Just like any API (application programming interface), a chatbot API acts as a bridge that enables the communication between different software. 

Think of it this way—your site is extending its virtual hand, and so is the chat platform. When they connect their hands, they can push and pull data between each other. This connection is what an API in chatbots is.

So, how does an API work in connecting a chatbot to your website?

How does a chatbot API work?

As you already know, chatbot API helps to link a channel to the bot software and increase the chatbot’s functionality. 

Thanks to chatbot API you can also add features that the provider doesn’t offer out of the box. These could include setting up your own automations or connecting the data from your system to the chatbot. 

For example, a user starts to interact with the bot on your website and asks a question about your pricing. This triggers the API to access the data from your website or another data source. In this way, the bot gets the relevant data and can compose a response for your user that would answer their question. 

So, essentially, the API helps chatbots to get relevant data to perform specific tasks, like answering a visitor’s question, placing an order, or making a booking.

Benefits of using chatbot API

Coding webhooks and chatbot features by yourself is time-consuming and costly. On the flip side, you can link your website data to the platform seamlessly when using APIs. Let’s look at the top three benefits of using chat API for websites. 

In comparison to coding a chatbot or adding features by yourself, using a chatbot API is: 

  • Faster

Trying to code the chatbot into your website, tweak its functionality or add any features by yourself would take a lot of trial and error, even if you’re an experienced programmer. Using chatbot APIs, on the other hand, is fast and efficient. You just need to find the right code on the platforms’ documentation page, copy it, do any small customizations, and paste it into your website’s code. That’s it—a few minutes of work, and it’s done!

  • Cheaper

Coming back to our point about using AI API being faster than doing the coding yourself—it’s also cheaper. The online chatbot API comes at no extra charge and only requires a bit of coding knowledge to use it. This way, you don’t have to spend thousands of dollars on your programmers’ time, just to make the chatbot work for your website. 

  • Secure

Chatbots are as safe as they make them. if you use the chatbot API accordingly, it’s a fairly safe way of installing a customized chatbot to your website. The developers of the software know it best and tested the code many times to ensure it works correctly, and it’s secure to use. So, to keep your chatbot’s code safe, utilize the code snippets instead of trying to make the changes yourself.

Keep in mind that you can use chatbots API for any website, whether it’s custom-made or based on a content management system (CMS) like Shopify or WordPress. It also doesn’t matter if you use a chatbot platform or a chatbot framework, as both should offer API documentation that you can utilize.
