Spec: Identify
The Innkeepr Identify call lets you tie a user to their actions and record traits about them. It includes a unique User ID and any optional traits you know about the user, like their email, name, and more.
We recommend that you make an Identify call:
After a user first registers
After a user logs in
When a user updates their info (for example, they change or add a new address)
Upon loading any pages that are accessible by a logged in user (optional)
The first three examples are pretty self-explanatory, but many might ask: why you would call identify on every page load if we’re storing the userId in the cookie/local storage?
Let’s imagine this scenario:
I log into your app. Identify is called. For whatever reason, I close the browser and don’t return until later. There’s no way of knowing where I will reenter your app from. I could start my session from anywhere. And because there are many tools out there that require an initial identify call for certain features (e.g. Intercom chat widget) it’s important to tell your end tools who the user is when they first start their session.
Calling identify is one of the first steps to getting started with Innkeepr. Refer to library-specific documentation for more details.
Here’s the payload of a typical identify call:
And here’s the corresponding JavaScript event that would generate the above payload:
Beyond common fields, an identify call has the following fields:
traits
optional
Object
userId
required; optional if anonymousID is set instead
String
Unique identifier for the user in your database. A userId or an anonymousId is required.
Example
Here’s a complete example of an identify call:
Identities
Anonymous ID
There are certain cases where you don’t actually know who the user is according to your database, but you still want to be able to tie them to traits, events, or page views. For example, you may not know who a user is when tracking newsletter signups or anonymous page views.
In these cases, you should use an Anonymous ID.
Note: Innkeepr’s libraries automatically use Anonymous IDs to keep track of users as they navigate around your website or app, so you don’t need to worry about them when using those libraries.
Here’s an example of a JavaScript event for an anonymous user:
User ID
User IDs are a more permanent and robust identifier, like a database ID. Since these IDs are consistent across a customer’s lifetime, identify calls should include a User ID as often as possible.
A User ID is usually the unique identifier that you recognize a user by in your own database. For example, if you’re using MongoDB it might look something like 507f191e810c19729de860ea.
We recommend using database IDs instead of simple email addresses or usernames, because database IDs never change. That guarantees that even if the user changes their email address, you can still recognize them as the same person in all of your analytics tools. And even better, you’ll be able to correlate analytics data with your own internal database.
Instead of using an email address or a username as a User ID, send them along as traits.
Traits
Traits are pieces of information you know about a user that are included in an identify call. These could be demographics like age or gender, account-specific like plan, or even things like whether a user has seen a particular A/B test variation. Up to you!
Innkeepr has reserved some traits that have semantic meanings for users, and we handle them in special ways. For example, we always expect email to be a string of the user’s email address. We’ll send this on to destinations like Klaviyo that require an email address to build targeting lists.
You should only use reserved traits for their intended meaning.
