I have used REST API's, t's easy to use and document is also good.

What I value the most about CometChat is their outstanding customer service. I trust that they will continue to offer timely help consistently in the future. I get quick responses for any problems, and their staff is always available to assist, whether by phone or other methods. Raising tickets is easy to do and provides great assistance. Moreover, CometChat's SDK is remarkable; it provides extensive APIs and is compatible with various technologies like React, React Native, and Flutter. In comparison to other SDKs, they offer a variety of functions such as calling, reactions, emojis, and additional features.
