Vero Destination

Our Vero destination code is all open-source on GitHub if you want to check it out: Javascript, Server.

Getting Started

Vero helps you send targeted emails to customers based on their behavior.

When you enable Vero in the Segment web app, your changes appear in the Segment CDN in about 45 minutes, and then Analytics.js starts asynchronously loading Vero’s m.js onto your page. This means you should remove Vero’s snippet from your page.

• Since Vero only records custom events and custom user data, no events or users will appear in Vero until you start using the API outlined below.

Vero is supported on the client-side, server-side and mobile.

Identify

Client Side

When you call identify on analytics.js, we augment traits to have traits.id set to the userId, and then call Vero’s user with the augmented traits object. You should provide both a traits.email and a userId for Vero to work best.

If no email is attached, the user is created in Vero but cannot be emailed. If you send omit the userId, Vero will use the email as the ID, which is is not recommended. Check out the Vero docs for more information.

A userId is a required value for all types of calls. Be sure you call identify with a userId for subsequent track calls to populate into Vero correctly. For server side calls, you will have to manually pass in the userId at the top level.

Server Side

When you call identify from one of our server-side languages, we’ll call Vero’s REST API and update the traits for the customer with that userId. If your userId is an email, we’ll also set the trait email as your userId in the update call.

Track

When you call track, we’ll send the event to Vero with the event name and properties you provide. Events will be matched to the current user.

You can also unsubscribe users by sending a track event, passing in the user’s ID as a property, like so:

analytics.track('Unsubscribe', {
  id: '12345'
});

Note: If you’d like to explicitly specify a user’s email with track events that is not an event metadata, you can send that under context.traits.email!

Sending Data from Vero

Vero supports sending email events to other tools on the Segment platform. These events will be sent as track calls to the other destinations you’ve turned on.

To enable this feature,

1. Log into Vero and go to Settings
2. Then go to Integrations
3. Hit ‘view’ next to the Segment integration
4. Enter in your Segment write key at the bottom.

Group

When you call group, the traits included in the call will be set to the current user’s Group property in Vero.

Alias

Our alias method can be used from your server to “re-identify” an existing user identity to a new one.

Most of the time this happens when you identify a visitor by their email address after they opt in, then later re-identify with a database ID when they become registered users.

To connect the two identities you’ll need to alias their current identity to their new one.

Here’s a python example of using alias to update the identity from an email address to a database ID:

analytics.alias('example@example.com', '8765309')

Features

Tags

The destination is capable of both adding and removing tags in Vero for a given user. Because tags is not a common property of events, this functionality is invoked using an destination specific option.

To start using this feature, pass an object called tags with the following properties:

Personas

You can send computed traits and audiences generated using Segment Personas to this destination as a user property. To learn more about Personas, contact us for a demo.

For user-property destinations, an identify call is sent to the destination for each user being added and removed. The property name is the snake_cased version of the audience name, with a true/false value to indicate membership. For example, when a user first completes an order in the last 30 days, Personas sends an Identify call with the property order_completed_last_30days: true. When the user no longer satisfies this condition (for example, it’s been more than 30 days since their last order), Personas sets that value to false.

When you first create an audience, Personas sends an Identify call for every user in that audience. Later audience syncs only send updates for users whose membership has changed since the last sync.

Supported Sources and Connection Modes

Before you start, make sure Vero supports the source type and connection mode you’ve chosen to implement. You can learn more about connection modes here.

Segment offers an optional Cloud-based Connection Mode for Web data with Vero. As a reminder, this removes the Vero javascript library from your site, improving performance.

Segment offers an optional Device-based Connection Mode for Mobile data going to Vero, so that you can use Vero features that collect data directly from the mobile device. To do this, you must package the Segment-Vero mobile SDK with the Segment mobile library.

Settings

Segment lets you change these destination settings from the Segment app without having to touch any code.
