Create and Log In a User
Guide Details:
This guide provides a step-by-step guide on creating and logging in a user using the CometChat platform with authentication using the Authentication Token. Additionally, you will need to make sure you have initialized CometChat in your app prior to logging in the user.
Introduction
To log in a user, they must first be registered on the CometChat server. For first-time logins, the user needs to be created in CometChat. After this initial creation, we can generate an authentication token for the user.
This authentication token, created via the CometChat API, will be used on the front-end to log the user into the CometChat UI Kit, SDK, or Widget.
Once the user is successfully logged into CometChat, we can proceed to request or post any necessary data for the app.
Please review our guide on How to Use the CometChat Authentication Token.
If using the Custom Widget, refer to the documentation on How to log in users using an auth token.
