HTTP source API

With our HTTP source, you can send data from anywhere directly to Data Pipelines without using an SDK. See our API documentation for more information about the Data Pipelines APIs.

 Examples on this page use our US region

If you’re in our EU region, you’ll use endpoints beginning with https://eu-api.customer.io/v1/ instead.

Connect an HTTP source

  1. In the Data Pipelines tab, click Sources.
  2. Click Add Source and select HTTP under the General category.
  3. Name your source. This will help you find and recognize your source in Customer.io moving forward.
  4. Configure your API call using the provided API key.
  5. Test that your source is connected. This will fail if you have sent no data through our Data Pipelines APIs or have sent data without the provided API key. You can choose to retest the connection or install your source at a later time.
  6. Select Complete Setup once your source is connected.

After you’ve installed your HTTP source, you can start making your own calls and add a destination to work with your new source.

Identify

The identify method tells Data Pipelines who the current website visitor is, and lets you assign unique traitsA key-value pair that you associate with a person or an object—like a person’s name, the date they were created in your workspace, or a company’s billing date etc. Use attributes to target people and personalize messages. Attributes are analogous to traits in Data Pipelines. to a person.

You should call identify when a user creates an account, logs in, etc. You can also call it again whenever a person’s traits change. We’ve shown a typical call with a traits object, but we’ve listed all the fields available in an identify call below.

You can send an identify call with an anonymousId and/or userId.

  • anonymousId only: This assign traits to a person before you know who they are.
  • userId only: Identifies a user and sets traits.
  • both userId and anonymousId: Associates the data sent in previous anonymous page, track, and identify calls with the person you identify by userId.

In most cases, you’ll simply provide userId, anonymousId, and traits, but we’ve provided the full list of writable-fields below. You’ll find the complete source payload in our API documentation.

  • anonymousId string
    A unique substitute for a User ID in cases when you don’t have an absolutely unique identifier. Our libraries generate this value automatically to help you track people before they sign up, log in, provide their email, etc.
    • active boolean

      Whether a user is active.

      This is usually used to flag an .identify() call to just update the traits but not “last seen.”

    • channel string
      The channel the event originated from.

      Accepted values:browser,server,mobile

    • ip string
      The user’s IP address. This isn’t captured by our libraries, but by our servers when we receive client-side events (like from our JavaScript source).
    • locale string
      The local string for the current user, e.g. en-US.
    • userAgent string
      The user agent of the device making the request

        A list/array of keywords describing the page’s content. The keywords are likely the same as, or similar to, the keywords you would find in an HTML meta tag for SEO purposes. This property is mainly used by content publishers that rely heavily on pageview tracking. This isn’t automatically collected.
      • name string
        The name of the page. Reserved for future use.
      • path string
        The path portion of the page’s URL. Equivalent to the canonical path which defaults to location.pathname from the DOM API.
      • referrer string
        The previous page’s full URL. Equivalent to document.referrer from the DOM API.
      • search string
        The query string portion of the page’s URL. Equivalent to location.search from the DOM API.

    The ISO-8601 timestamp when the event originally took place. This is mostly useful when you backfill data past events. If you’re not backfilling data, you can leave this field empty and we’ll use the current time or server time.
    • createdAt string  (date-time)
      We recommend that you pass date-time values as ISO 8601 date-time strings. We convert this value to fit destinations where appropriate.
    • email string
      A person’s email address. In some cases, you can pass an empty userId and we’ll use this value to identify a person.
    • Additional Traits* any type
      Traits that you want to set on a person. These can take any JSON shape.
  • type string
    The event type. This is set automatically by the request method/endpoint.

  • version number
    The version of the API that received the event, automatically set by Customer.io.

Track

The track method tells us about actions people take—the events people perform—on your site. Every track call represents an event. When you send an event with a track call, you can provide associated properties about the event. For more information, see the track method reference.

You should track events that are indicators on your site, or the kinds of things that you want to know that your audience does on your website, like Video Viewed, Item Purchased or Article Bookmarked. In some products—like Customer.io Journeys—you can use events to trigger messages and other downstream actions.

You can send events with an anonymousId or a userId. Calls that you make with an anonymousId are associated with a userId when you identify someone by their userId.

Track calls typically contain an event name—so you know what a user did—and a series of properties, which contain additional information about the event. The examples below show added_to_cart events, containing properties that let you know about the product a person added to their shopping cart.

In most cases, you’ll simply provide an ID for the user, the event, and properties, but we’ve provided the full list of writable-fields below. You’ll find the complete source payload in our API documentation.

You can use objects to message people based on changes to their company, account, or course itinerary..

Group calls are useful for destinations where you maintain relationships between people and larger organizations, like in Customer.io! In Customer.io Journeys, you can store groups as objectsNot to be confused with a JSON object, an object in Customer.io is a non-person entity that you can associate with one or more people—like a company, account, or online course. You can use objects to message people based on changes to their company, account, or course itinerary., and trigger campaigns based on a person’s relationship to an object—like an account, online class, and so on.

Find more details about group, including the group payload, in our API spec.

In most cases, you’ll simply provide an ID for the user, the groupId, and traits, but we’ve provided the full list of writable-fields below. You’ll find the complete source payload in our API documentation.

Alias

The Alias method combines two previously unassociated user identities. Some destinations automatically reconcile profiles with different identifiers based on whether you send anonymousId, userId, or another trait that the destination expects to be unique. But for destinations that don’t, you may need to send alias requests to do this.

In general, you won’t need to use the alias call; we try to handle user identification gracefully, so that you don’t need to merge profiles. But you may need to send alias calls to manage user identities in some destinations.

For example, in Mixpanel it’s used to associate an anonymous user with an identified user once they sign up.

  • previousId string
    Required The userId that you want to merge into the canonical profile.
  • userId string
    Required The userId that you want to keep. This is required if you haven’t already identified someone with one of our web or server-side libraries.
