Address Book API provides an interface to work with the phone address book. Upload it to the server and retrieve already registered QuickBlox users from your address book. Visit Key Concepts page to learn the most important QuickBlox concepts.

​
Before you begin

  1. Register a QuickBlox account. This is a matter of a few minutes and you will be able to use this account to build your apps.
  2. Configure QuickBlox SDK for your app. Check out Setup page for more details.
  3. Create a user session to be able to use QuickBlox functionality. See Authentication page to learn how to do it.

​
Upload address book

First of all, you need to upload your address book to the backend. It’s a normal practice to do a full upload for the first time and then upload new contacts on future app logins.
JavaScript
let contact = {};
contact.name = "Apple service";
contact.phone = "1-800-275-2273";
let contactsArray = [contact];
let options = {
  force: 1,
};

function addressBookSaved(error, result) {
  if (error) {
    console.log(error);
  } else {
    // process response
  }
}

QB.addressbook.uploadAddressBook(contactsArray, options, addressBookSaved);
  • You also can edit an existing contact by providing a new name for it.
  • You also can upload more contacts, not just all in one request. They will be added to your address book on the backend. If you want to override the whole address book on the backend just provide force: 1 option.
  • A device UDID is a unique device identifier. The UDID is used in cases where a user has two or more devices and contacts sync is off. Otherwise, a user has a single global address book. The UDID maximum length is 64 symbols.

​
Retrieve address book

You can retrieve your uploaded address book using the code snippet below.
JavaScript
function addressBookSaved(error, result) {
  if (error) {
    console.log(error);
  } else {
    // process response
  }
}

QB.addressbook.get(addressBookSaved);
//with UDID
QB.addressbook.get(UDID, addressBookSaved);

​
Update contacts

If you need to update the name or phone number in your address book contacts, you should use the code sample below.
JavaScript
let contact = {};
contact.name = "Apple service";
contact.phone = "1-800-275-2273";
let contactsArray = [contact];

function prepareForUpdate(contacts) {
  return contacts.map(function (contact, index) {
    contact.name += " Updated";
    return contact;
  });
}

var contactsUpdated = prepareForUpdate(contactsArray);

function addressBookUpdated(error, result) {
  if (error) {
    console.log(error);
  } else {
    // process response
  }
}

QB.addressbook.uploadAddressBook(contactsUpdated, addressBookUpdated);

​
Delete contacts

You can delete contacts by using the code snippet below.
JavaScript
let contact = {};
contact.name = "Apple service";
contact.phone = "1-800-275-2273";
let contactsArray = [contact];

function prepareForDestroy(contacts) {
  return contacts.map(function (contact, index) {
    if (index % 2 !== 0) {
      delete contact.name;
    }
    contact.destroy = 1;
    return contact;
  });
}

var contactsDestroy = prepareForDestroy(contactsArray);

function removedContacts(error, result) {
  if (error) {
    console.log(error);
  } else {
    // process response
  }
}

QB.addressbook.uploadAddressBook(contactsDestroy, removedContacts);
//with UDID
var options = {
  udid: UDID,
};
QB.addressbook.uploadAddressBook(contactsDestroy, options, removedContacts);

​
Retrieve registered users

Using this request, you can easily retrieve the QuickBlox users - your address book contacts that are already registered in your app. Users are matched with address book contacts by phone number, so user and address book contact must have the same phone number to be included in response.
JavaScript
function addressBookGot(error, result) {
  if (error) {
    console.log(error);
  } else {
    // process response
  }
}

QB.addressbook.getRegisteredUsers(addressBookGot);

​
Push notification on new contact joined

There is a way to get a push notification when some contact from your Address Book has been registered in the app. You can enable this feature at QuickBlox Dashboard. Just follow Dashboard => YOUR_APP => Users => Settings direction and enable push notifications for new contacts.
