# For this plugin to work, you need to add the Maker applet to your profile
|
|
# Simply visit https://ifttt.com/search and search for 'Webhooks'
|
|
# Or if you're signed in, click here: https://ifttt.com/maker_webhooks
|
|
# and click 'Connect'
|
|
#
|
|
# You'll want to visit the settings of this Applet and pay attention to the
|
|
# URL. For example, it might look like this:
|
|
# https://maker.ifttt.com/use/a3nHB7gA9TfBQSqJAHklod
|
|
#
|
|
# In the above example a3nHB7gA9TfBQSqJAHklod becomes your {apikey}
|
|
# You will need this to make this notification work correctly
|
|
#
|
|
# For each event you create you will assign it a name (this will be known as
|
|
# the {event} when building your URL.
