CRM Properties

CRM Properties are stored securely only on the Hackle server and cannot be directly queried through the SDK.

CRM Properties are managed separately and are not deleted or reset even if you call resetUser() or clearAll in updateUserProperties.

If a user withdraws their account, you must call the separately provided function to delete the information.

Phone Number Collection

This feature is supported in Flutter SDK 2.16.0 and above.

Kakao / Text Message Recommendation

By using this feature to map the User Identifier to a phone number, you can more seamlessly use Kakao messages and Text Messages through Hackle.

setPhoneNumber

Registers the user's phone number.

The phone number is stored only if it is in valid E.164 format. If no country code is specified, South Korea (+82) is used as the default.

If the user already has a stored phone number, calling this function replaces the existing phone number with the new value.

String myPhoneNumber = '[phone]';
HackleApp.setPhoneNumber(myPhoneNumber);

unsetPhoneNumber

Deletes the phone number registered for the user.

HackleApp.unsetPhoneNumber();

CRM Marketing Subscription Consent

This feature is supported in Flutter SDK 2.20.0 and above.
