Built-In Identity Types
Identity types are specific identifiers that determine how Personalization processes web events, API events, and channel events to identify users from various sources. Personalization includes several built-in identity types, such as email address and customer ID. The built-in identity types don’t require configuration other than setting up event capture mechanisms, such as the sitemap or ETL jobs.
Many built-in identity types are available for the identity system to use for identity lookup and merging user profiles. If these identity types don't meet your needs, you can create 3 extra identity types.
| Identity Type | Settings |
|---|---|
| Email Address |
|
| Profile ID |
|
| Salesforce CRM Lead ID |
|
| Salesforce CRM Contact ID |
|
| Customer ID |
|
| Salesforce Marketing Cloud Engagement Contact Key |
|
The Email Address, Engagement Contact Key, and Customer ID identity types already have corresponding user profile attributes. To use the Salesforce CRM Lead ID and Salesforce CRM Contact ID identity types, follow the steps in Create a User Profile Attribute to set up the associated attributes.
