Why write when you can integrate? What will you do if you are given an option like this? Whether you are a business owner or an experienced developer, you would take a shot at this. Because, the time, cost, and resources required in chat application development are way higher than using a ready-made chat API and SDK.
Understanding this need, a new chat API emerges every other second making it difficult for developers to choose the best one. Besides the fact that an API has to be cut and dried, it also should be affordable.
So, in the blog below let us glance at some of the providers who offer chat API service free for a certain time frame or particular features. Hold tight till then!
What are Chat APIs?
A chat API (Application Programming Interface), in layman terms, is an interface that allows you to connect with the server side and offer real-time chat features on any application or website.
In case the above-said was a little techy, an API is like a ‘plug-and-play component that can be embedded into any mobile or web app for creating custom chats’. Usually, APIs are a part of software development kits that businesses use to integrate certain features into their chat framework.
They prefer this option because it is economical, saves time, and primely reduces rework. But, is it all that an API offers to its users? The answer is No!
Why Should You Use Chat APIs & SDKs?
An API always saves developers time and resources when creating a complicated feature. But, in addition to this, they are also known for benefits like:
- Free to start
- More secure than apps built from scratch
- Quick chat integration
