Tasks
Put the internet to work for you by creating tasks that fit this simple structure:
if this then that
Think of all the things you could do if you were able to define any task as: when something happens (this) then do something else (that).
Triggers
if this then that
The this part of a task is the Trigger. Some example Triggers are “if I’m tagged in a photo on Facebook” or “if I tweet on Twitter.”
Actions
if this then that
The that part of a task is the Action. Some example Actions are “then send me a text message” or “then create a status message on Facebook.”
Channels
Triggers and Actions come from Channels. Channels are the unique services and devices you use every day. Some example channels:
Twitter

Instagram

Weather

All together now
When you put one channel’s trigger together with another channel’s action, that’s a task! Here is a task that saves every new photo I take with Instagram to my Dropbox:
if instagram then dropbox
Recipes
Create a recipe to share a task with friends. Here is a recipe for the task above:
instagram to dropbox
On/Off
Tasks can be turned on and off. When turned back on, they pick up as if you had just created them.
Polling period
Tasks poll for new trigger data every 15 minutes.
