Creating Applets

The Applet creation tool is designed to help you build valuable Applets and publish them for the world to use. Your Applets can have multiple actions and custom filter code to go beyond the basic “if this, then that” paradigm. If there are terms below that you don't understand, check out the glossary.

Some tips on using the tool

  • Applet title: Be specific. This is your chance to tell the user what they should expect this Applet to do for them — approach it like you would writing an instruction manual, instead of a catchy headline. Keep it short and to the point.

  • Applet description: This is where you can add in details about triggers and actions, and any information the user should customize, such as location or a hashtag.

  • Trigger: Select the trigger that you’d like to use for the Applet. The tool allows you to select from all services on IFTTT that have at least one trigger.

  • Trigger fields: The tool allows you to either hide or show trigger fields to the user when turning on the Applet. If the value for the field should be the same for all users, fill out the field and mark it as hidden. For example, if your Applet is “Tweet new technology articles from the New York Times”, you would select “Technology” for the NY Times “Section” trigger field and then hide it. If your Applet is “Tweet new articles from a section of the New York Times” you would mark the “Section” field to be chosen by the user.

  • Queries: Coming soon is the ability to query for information to be used as filtering conditions or to provide more data to be used in an action run.

  • Filter: You can write simple filter code which dictates which actions should run based on the trigger data coming in.

  • Action(s): You can select one or more actions to run when the trigger event occurs. Add additional actions by clicking the “Add action” button. Keep in mind that users must have activated all services used in the Applet in order to turn it on.

  • Action fields: Like trigger fields, data can be pre filled and hidden in an action field or can be filled out by the user. In the case of action fields, it is important to hide any fields that don’t need to be filled out by the user. For example, if your Applet is “Tweet your Instagram photos”, you would place the Instagram “SourceURL” ingredient in the Twitter “Image URL” action field and then hide it as this is the only appropriate ingredient to have in that field. You might ask the user to fill out other types of action fields themselves such as their location, their email address, or a name of a photo album private to them. Note that action fields marked to be “chosen by the user” can include prefilled text or numbers, but cannot include prefilled ingredients.

Using filter code

When you build an Applet with the creation tool, you can use the filter code feature to add extra flexibility and power by writing your own JavaScript that runs whenever the Applet does. Your code has access to the data returned by the trigger, as well as metadata like the current time in the user's time zone, and it can use that information to override action field values or skip actions.

See the Applets Cookbook section for some examples of what you can do with filter code.

There are some fields that are always available:

  • Meta.currentUserTime: The current time when your code is evaluated, in the user's timezone. This returns a Moment.js object.

  • Meta.triggerTime: The time that the trigger event happened, in the user's timezone. This should be close to currentUserTime, but could vary depending on the polling period of the Applet's trigger. This returns a Moment.js object.

There are additional fields available depending on the specific trigger and actions that your Applet uses. For example, if your Applet uses the Weather Underground service's "Sunrise" trigger, your code can use Weather.sunRises to get the trigger's ingredients. If it uses the LIFX service's "Toggle lights on/off" action, your code can use Lifx.toggle to override that action's fields or skip it instead of running it.

The trigger's object contains the values of each of the trigger's ingredients. If you're using the "Sunrise" trigger, you can get the current temperature in Celsius by writing Weather.sunRises.TempCelsius. For convenience, you can also just write Trigger.TempCelsius, since an Applet can only have one trigger. Note that the ingredient values are always strings, even when they represent numeric data.

Each action's object has the following methods:

  • skip(): This lets you skip an action instead of running it. You can optionally provide a message that will be shown in the user's event feed to explain why the Applet decided not to run the action.

  • set[FieldName](): For each hidden field of the action, you can use a correspondingly-named setter method to override its value. If you do, the value you provide will be used verbatim, skipping the templating step that normally happens with hidden fields. If you want to use ingredient values, you can do so by just using string concatenation or JavaScript template literals:

  `The sun rose at ${Weather.sunRises.SunriseAt}`

When you override the value of a dropdown field, the argument you pass in should be the option's value, not its label. The filter code editor has autocomplete support for dropdown field setters to make this easier.

Technical details

  • When you write filter code, you're technically writing TypeScript, not JavaScript. This helps prevent runtime problems with your code by catching simple mistakes as early as possible. You should generally be able to just write normal JavaScript, but the TypeScript documentation may be helpful if you run into issues with more advanced use cases.

  • Filter code is run in an isolated environment with a short timeout. There are no methods available that do any I/O (blocking or otherwise), so your code should execute quickly.

Testing and publishing your Applets

  • When your Applet has been all filled out, click the "Preview" button to create a private version of the Applet.

  • Visit your service page to try out the Applet to make sure that it is working as expected. Private Applets can be modified based on your testing.

Applets Cookbook

In this section we provide a series of examples of Applets that take advantage of the Filter Code. It is important to note that JavaScript (Typescript) is a full-fledged programming language - if you need help you might consider participating in the Maker community on or learning JavaScript.

Example: Random light colors

Applet description

  • Random light colors
  • Change your LIFX colors to a random color


  • Button Widget: Button Press

Filter code

var colors = ["#FF8400", "#FF0000", "#15FF00", "#FF00D4","#00D4FF","#003CFF"]
var index = Math.floor((Math.random() * colors.length))
Lifx.color.setAdvancedOptions('color: ' + colors[index] + '; brightness: 1; duration: 12')


  • Lifx: change color of lights

Example: Adjust your lights as it gets darker outside

Applet description

  • Adjust your lights as it gets darker outside
  • Change your LIFX light bulbs to reflect the color outside and have a more natural color as it gets darker outside


  • Date & Time: Every hour

Filter code

var hour     = Meta.currentTime.hour()
var colorKey = hour.toString()

var colors: {[key:string]:string} = {

if (hour < 17) {
  Lifx.color.skip("Too early")
} else if (hour < 22)  {
    'color: ' + colors[colorKey] + '; brightness: 1; duration: 12'
} else {
  Lifx.color.skip("Too late")


  • Lifx: change color of lights

Example: Flight deals from or to San Francisco

Applet description

  • Flight deals: San Francisco
  • Get a daily email with flight tickets on sale below $400.00.


  • Twitter: New tweet from search
  • This Applet uses a search field (hidden from the user) with value: (from:SecretFlying OR from:AirFareSpot OR from:FTMileageRuns OR from:ThePointsGuy OR from:airfarewatchdog) AND (SanFrancisco OR "San Francisco" OR SFO OR "SF" OR "SFBayArea" OR OAK OR "Oakland" OR "Bay Area")

Template for creating an IFTTT Applet

Filter code

var txt = Ingredients.Text || ""
var price = parseInt((txt.match(/\s\$(\d+)\s/) || [])[1])

if (price > 400) {
  EmailDigest.sendDailyEmail.skip("Too expensive")


  • Lifx: change color of lights

Example: Daily motivational quote

Applet description

  • Daily quote
  • Receive a daily motivational quote on your phone and a weekly digest with all the quotes.


  • Date & Time: Everyday at a time chosen by the user
