Phonebook API enables you to manage your Phonebook or use our blacklisting feature to make sure you're not sending any unwanted messages.
Groups and Contacts
Using Phonebook API you can manage the Phonebook in Messente - both Groups and Contacts in them.
Or you could think of Groups as Labels and assign them to Contacts - it works both ways, whichever way it fits better with your business logic.
Blacklist is a list of numbers that is tied to one specific Account. All messages sent using any API credentials from this account, are passed through this list.
If the number is in the blacklist, the message is not sent - it applies both to API calls and messages sent from the Dashboard.
