If an identifier other than email is provided, global marketing consent will be shown for the last seen email address on the customer profile. List subscriptions are set at the profile level, but can be queried based on any customer identifier.
ts_status_updated value in the response will indicate the last time the
subscribed value was changed. If the customer has never been subscribed to a list, the
subscribed value is false and the
ts_status_updated value is null.
explicit_opt_in Boolean value in the response will indicate if the email address explicitly consented to receive marketing messages, or if global marketing consent is null. Learn more about implicit and explicit consent in the Optimizely Help Center.
explicit_opt_in will be false when global marketing consent is false or null.
