What’s an API, and why use it?

API or Application Programming Interfaces are small pieces of code that help digital devices, software, and data servers to communicate with each other. It is a software to software interface and does not require any user intervention. In simpler words, think of an application that you use every day. These applications are meant for humans to use but APIs are designed for use by digital systems and applications to interact with each

other. Like any website, a video call API for iOS also returns data, images, video, content, etc.; but it cannot return every detail in a form that humans can understand. It returns only raw data and machine-readable information to put the resources to work. 

APIs allow developers to add features and functionality to the apps. With an API, developers do not need to start building an app right from the scratch. This can save a lot of their time and money. Many product teams prefer to use APIs to integrate common features but not for the features unique to their own product. Here are a few real-world examples of API categories that are used widely:

  • Payment processing (Stripe)
  • Customer support chat (Mixpanel)
  • Sending email from an app (Mailchimp)
  • Text chat (CONTUS MirrorFly)
  • Video chat (CONTUS MirrorFly)

Choosing a good video chat API for product functionality, saves money and effort, as it gives the benefits of proven flexible technology. One does not have to struggle to solve technical issues that are already solved. The team can focus on their core product and their core functionalities.

7 Video Chat Required When Building A Video Chat Application

Easy registration and creation of user profile

App developers need to ensure that building a user profile or signing in the application needs to be a simple step. Avoid any complex registration process. 

Contact list

App developers should ensure that the contact list can be easily imported or exported. Ideally, this process is done manually and is still offered by other API providers, but to make the process simple and easy the former can be conducted. 

Voice and video calling

Voice and video calling features should be provided. This includes secure recordings, encrypted chat, 1-1 group calls, and much more. Voice and video calling are highly used communication platforms and this should be given as an option when building video chat applications. 

Text chat

In case if the video quality or network is compromised, app developers should let users text chat until the former is alright. This eliminates such disturbances before they can make an impact. 


Security matters as during video calling sessions, information will be shared that needs to be protected. Hence ensure that all security measures such as HIPAA compliant, end-to-end encryption, and more are used. 


Notifications are a great feature to add to the video calling apps. With the former, all details about missed calls and more can be easily exhibited. 

Data backup

It is important to have backup storage of the data. Invest in a reliable communication API provider that has an inbuilt database and scales accordingly in the cloud infrastructure.

While the above features are needed when building a video chat app, having additional features can enhance the latter better. 

To name a few are:

Virtual background

Meetings don’t have to be boring hence to make it more interesting, app developers like you can easily provide the option to change the background of video calls into images or plain backgrounds.

Understanding Video Chat APIs: Low-Level Apis and New Approaches

Understanding Video Chat APIs

These are exciting times for online videos. Online video conferencing is a supportive means to all types of organizations. So, when you want to incorporate video conferencing software for organizational use, many questions pop. Whether should you build this functionality internally, or is it easier to use a video chat API? Also whether would you want to use a low-level API or a newer API with more features and prebuilt UIs? In this post, we will discuss what an API is and how do they function. Also, we will get you deeper into low-level API versus higher-level APIs. 

Low-level vs full-featured APIs: What difference does it make?

Now that you have decided to add video conferencing to your website and use APIs, you need to know that APIs have different levels of functionalities. This is the time to narrow down your search to know what type of API, from which vendor would you want to use.

Low-Level API programming interfaces are very detailed, as it lets the programmer tweak functions within the software or within the hardware at a base level. Well-elaborated low-level APIs are very powerful. Experienced programmers like to use them since these APIs have a wide range of capabilities and efficiency. Low-level APIs are more customizable and extend free functionality to vendors. 

In other words, they give you more control, but more effort goes into writing codes to create functional features.  Let us understand this with an example. When we decide to build a house, there are several ways to venture into it. 

Get an assembled and finished house delivered with solid warranties and servicing conveniences. Get your customizations done on the prefabricated house for the personalized effect by hiring professionals or tweaking the standard plans.  

You gather a team of professionals like an architect, contractor, and electricians, etc. to build the house from square one. You take a step ahead and head to the woods to choose the trees you want to use, gather your choice of stones to set the foundation. 

Hence there is a scale at which you want to work from the first option to the last one. APIs work in a similar manner, the more you inspect, and more you need to get into intricacies. And if you want to take control of each area, you may need more time, money, and expertise.  A “Low-level” API resembles step 4 when you decide to pick your woods yourself or add a live video call app from the genesis. 

In a full-featured API, there are pre-structured fragments to work with. Full-featured API provides the capabilities equivalent to the most advanced APIs. The user gets the advantage of full features with less development labor, testing, and maintenance. During a video call, millions of codes run from your own app to the other operating systems and network servers. All of this can be achieved by clicking the button. They can provide more functionality and are easier to use without delving deep into the technicalities.  

Low-level vs full-featured APIs

Low-level code in a video call handles raw audio/video data, compression, encryption, routing, bandwidth, and connections between devices and servers. 

The codes to set up connections between devices and network servers, make a video call function, are also low-level codes. Coding for the user interface of the live video chat app, buttons and controls (that are visible) to the users are higher-level codes.

Finally, your choice of API boils down to the factors like how much time, focus, resources, and expertise you want to use.


How much video chat do you want to build?

As we have seen above, there are two possible ways to build live video chat apps. The first is to build it from scratch and the other is to use a ready-to-use white-label video chat app. Choosing a 

Video chat API, gives the liberty to decide how much of the coding work you want to take up? One can choose to have a low-level API or opt for more flexible, full-featured APIs or build a live video call app from the beginning. Full-featured video chat APIs like CONTUS MirrorFly lets you have a complete video chat widget with very little use of native codes. CONTUS is a noticed name in this marketplace for providing outstanding features, with a flawless user experience when it comes to APIs.
