How to get Webhook ID & Token

Create the Webhook

At Discord you can create a Webhook for a specific channel. Just go into the channel settings at the point "Webhooks".

After clicking on "Create Webhook" you can specify a Username and a avatar for the Bot User.
At the bottom of the window is the webhook url that you need to copy.

For my Webhook that i created for now the url is the following: https://discordapp.com/api/webhooks/318821398619357185/czD2ExfFEHWLC0rONDOX5boZShaj6iU6htegr6t9TYcscxHw9BYpQbWaJ6kWzp4kChtO The first part after https://discordapp.com/api/webhooks/ is your Webhook ID. In my case it would be 318821398619357185.
The Webhook Token is the rest of the URL. In my case it would be czD2ExfFEHWLC0rONDOX5boZShaj6iU6htegr6t9TYcscxHw9BYpQbWaJ6kWzp4kChtO
