2. Chat UI
To speed up the front-end part of the integration, chat APIs offer a back-end-as-service and UI components or Sketch designs (UI design kit). Twilio requires you to design and build the chat UI from the ground up, giving you total control over the design. However, this may take a few months to accomplish. TalkJS is a single-package chat solution that includes both the frontend and backend. You will receive the infrastructure, code, and a fully working chat with customizable UI (Themes), including the design. Because the UI is forward compatible, the chat will continue to function on future devices, browser bugs, and new features. That is, a chat solution may be set up in hours. The TalkJS theme is a CSS file with specific properties that you may use to customize the UI’s look and feel. The introductory chat UI layout remains the same, but you can customize it to match your site’s design. The updated version of the themes takes the concept to a whole new level.3. Multichannel messaging API
Twilio is the market leader in Web chat APIs, with a comprehensive feature set and flexible choices. Its APIs span all forms of digital communication, including programmatic SMS and MMS, WhatsApp, audio and video, conversational chat APIs, Facebook Messenger, and Google’s Business Messages. Twilio allows developers to link their application software with practically any communication channel. Furthermore, the conversations API allows you to start with a single channel, such as online or in-app chat, and then quickly extend to other channels (MMS, voice, video, chat) as customer preferences change. The best aspect is that adding a new channel does not necessitate rebuilding your entire back end or code against a brand-new API. TalkJS is a messaging API that focuses on making it as simple as possible to create chat apps. Though it isn’t as robust or feature-rich as some of the other options, it allows them to set up a chat experience on their website with only a few lines of code. TalkJS is an attractive option for enterprises that desire the capabilities of real-time messaging software without having to spend much on a development team. Hence, if you require a chat feature for direct messaging, a chatroom, or group chat, then TalkJS chat API should be chosen.4. Support
