Written by Olesia Melnichenko

Chatting rules! Seriously though, the world revolves around texting to family, friends, support team, delivery guys…Insert your option.
Come to think of it, we spend almost 3 hours and 15 minutes on our phones. Let alone the time it takes to tackle some burning issues.
According to another report, 9 out of 10 customers prefer sending messages to a brand rather than calling. There’s a tendency that all the chatting becomes a buzzword yet a preferred communication tool. And if you’re a startup owner or in charge of a business, think wisely. Getting the picture?
I am talking about creating your own in-app messaging hub but without a team of technology junkies. Trust me, it’s not rocket science. All it takes is to choose a chat API package and you’re good to go.
What are chat APIs?
Chat APIs (Application Programming Interface) represent a set of components that gives access to the back-end server environment and provides real-time chat features to your application.
A chat API can be easily embedded with development documentation or by using a chat SDK (Software Development Kit). Speaking of, the latter comes in a downloadable package and involves ready-to-use instructions for developers to generate applications.
Assisting communication between user to user, business to customer, business to business, or service provider to the customer – chat APIs can help you shape awesome chat tweaks that fit your brand.
What are chat APIs benefits?
You might already have an idea of how an instant messaging API can transform your experience while utilizing an app and creating your best chat solutions. I give you three reasons:
- Budget-friendly: thanks to predesigned APIs and SDKs, you can cut costs on workforce or finance and build an app without tedious tasks. All the processes will be simplified.
- Secure: not to mention you even don’t have to fret over your security (disclaimer: the list below features solutions that are 100% secure).
- Beneficial: APIs and SDKs are not only developer-friendly but also easily accessible for users. They can actually change the entire app creation experience. It means software delivery will be faster and glitches free.
Who benefits from chat APIs and how
If you think that the things we are talking about today are used only in the tech industry, think again. As a matter of fact, a chat SDK and API are found in many industries. Here are some of them:
- E-learning: it’s on high stakes today as more and more people all around the world make online education their first choice. Chat APIs play a supportive role here: teachers and students can communicate with each other in person and in real time without switching to another third-party platform.
- Live streaming: turning conversations and performing live is what brings money and fame to many bloggers and influencers out there. Such a distant communication would be next to impossible without APIs. No need to leave your platform.
- Healthcare: all the convenience lies in a live communication feature that helps in counseling patients online. Be sure that your interaction with users will be totally secure and leakage-proof.
- On-demand service: this industry includes food or grocery stores and delivery. A chat API service is a silver bullet here as you can actually choose products right in your app, reach out to a delivery man to see if your order is OK, or report a problem. It all happens online.
What should a chat API service provide?
Before you decide on a chat API service for your mobile app or website, check if it meets all your business technical and non-technical needs. Here’s what you should pay attention to in the first place:
- A group messaging option/ 1-1 messaging/ open public chat
- Push notifications
- Devices and platform supported (Android, iOS, web)
- Custom data transfers
- Chat history
- Delivery status
- Analytics
- Online/offline status
- Authentication type (single sign-on, email, OAuth, two-factor)
- Technologies used (REST, Ajax, WebSockets, XMPP)
However, it’s not cut and dried. Some chat APIs may involve advanced features such as webhooks, a chatbot integration, an anti-spam option, typing indicators, moderation tools, to name a few.

Are you developing a dating app? Or trying to build a social community? This chat API service is at your fingertips. Sounds intriguing, doesn’t it?

Despite all the perks, Vonage lacks automatic notifications, instant messaging, customizable branding, and contact management.
So, taking our comparison of all chat APIs into account, what would you choose? I bet you’re about to make the right call.
Prices: There are multitiered pricing packages, but you can start from a trial (no credit card required).
10. Smooch

Zendesk’s product Sunshine Conversations by Smooch is the last in our extensive list though not the least in what it has to offer.

There’s always room for perfection. The fact that this solution is rather expensive and has few customization options gives a trigger for improvement for the user’s sake.
