# Amazon Chime Incoming Webhooks
#
# To create an incoming webhook for an Amazon Chime chat room:
# 1. Open Amazon Chime and navigate to the chat room you want to
# send notifications to.
# 2. Choose the gear icon in the top-right corner of the chat room.
# 3. Choose "Manage webhooks and bots".
# 4. Choose "Add webhook", give it a name, then choose "Create".
# 5. To copy the webhook URL, choose "Copy URL" next to your new
# webhook in the list.
#
# The webhook URL will look something like:
# https://hooks.chime.aws/incomingwebhooks/
# xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx?token=AaBbCcDd%3D%3D
#
# Where the path segment after /incomingwebhooks/ is the Webhook ID
# and the ?token= query parameter is the authentication token.
#
# Your Apprise URL would be assembled as:
# chime://{WebhookID}/{Token}
#
# For example:
# chime://xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/AaBbCcDd%3D%3D
#
# The token value may include base64 padding characters (=). Apprise
# handles encoding automatically; you can paste the token exactly as
# it appears in the Chime webhook URL (already URL-decoded form) or
# as-is from the ?token= query parameter.
