This example creates an application command, listens for an interaction (while connected to the Discord Gateway), then responds to the interaction. The bot waits until the program receives a signal to terminate, then disconnects from the Discord Gateway and deletes the created command. For more information about Application Commands, read the Discord API Documentation.
Use this example to create commands users can interact with.
You must create a Discord Application in the Discord Developer Portal to receive your Bot Token.
Assign an environment variable in the command line you will be running the program from.
set TOKEN=value
set APPID=value
export TOKEN=value
export APPID=value
NEVER SHOW YOUR TOKEN TO THE PUBLIC.
NOTE: Get the Application ID by enabling Developer Mode from the settings of your account, then right clicking your bot.
Use go build to build the executable binary. Use command to run it from the command line.

I am receiving Invalid interaction application command from Discord when I send an interaction.
Discord propagates registered Global Application Commands. As a result, it can take time to add or update a Global Application Command. In addition, the user's client must reload the commands that are available to them, so that the user's client selects the new propagated Global Application Command (with a new ID and Token). In contrast, Guild Application Commands (registered via CreateGuildApplicationCommand) are updated instantly. Due to this behavior, use Guild Application Commands to test your application without waiting for propagation. For more information, read the Discord API Documentation.
I am receiving a nil pointer dereference when the Bot's Application Command is used in a DM or Guild.
When an Application Command is used in a direct message, the Interaction.User field is provided, while the Interaction.Member is NOT. When an Application Command is used in a guild, the Interaction.Member field is provided, while the Interaction.User is NOT. For the sake of simplicity, these examples assume that you will use your command in a Direct Message Channel. To protect against this behavior in production-level code, ensure that the Interaction.User or Interaction.Member is != nil before referencing their fields.
