How do you set the type when creating an identity namespace via the API?

To set the type when creating an identity namespace via the API, it is necessary to specify the key of the idType in the request body. This approach allows you to clearly define what type of identity is being created for the namespace, ensuring that the data model aligns with the types of identities your platform will manage.

In the request body, you include a structured format that delineates the various components of the identity, with idType being crucial as it indicates the specific classification of the identity, such as email, phone number, or a customer ID. This clarity is essential for correctly managing identities within Adobe Experience Platform, enabling effective data governance and user interactions.

The other methods mentioned do not pertain specifically to defining identity types in the context of creating an identity namespace. Defining a schema URL typically involves mapping to a data structure rather than specifying identity types. A global identifier can serve a different purpose, focusing on unique identification across systems without necessarily defining its type. Using environment variables is more about managing configuration settings for applications and does not relate directly to the identity namespace setup process. Thus, specifying the key of idType is the most accurate approach in this scenario.
