Chatwoot is designed to work alongside the project communication application you use in your project. Slack and Webhooks are already integrated with Chatwoot. You can also connect your own apps using Dashboard Apps.
To begin setting up, click on Settings on your homepage. Next, click on Integrations. You can see the screen which displays the already installed integrations.
If your account/project is using Slack as medium of communication, click on the "Connect" button against Slack in the Integration window.
A screen opens up where you can directly give the workspace Slack URL to connect to your Slack account. That is all you need to do!
If your Account/Project is using Webhooks for communication, click on the "Configure" button against Webhooks in the Integration Window.
Click on the "Add New Webhook" button on the right hand top side of the screen.
A screen opens up where you can enter the details of the the new Webhook you want to create.
