I am trying to implement a feature in my app, where users can see a contact list of which contacts (based on mobile number) already has an account on our app.
This feature can be found in all social media and banking apps.
Can someone guide on how to do so?
You can use https://www.npmjs.com/package/react-native-contacts to get all the contact details, then pass this array to your backend service to find the accounts with the phone number, then you can display them.

Currently, I am using WhatsApp Business api cloud on one of my web project, I would like to register a customer's phone number but via api instead through meta, developer platform like following:
"Here is the image to register customer's number in the meta developer platform"
I want do this:
(managing the phone numbers)
but via api, and later of that send the verification code via api as well.
If someone can help me , telling me if that is possible and sharing documentation or the endpoint I would appreciate it very much, I've been looking at the documentation and postman's examples for 2 days without any success.
I'm sorry I didn't share the pictures directly, it is my first question on Stackoverflow
Thanks in advance,
Greetings!
I guess you are using WhatsApp provided a test phone number in From, you need to read this, https://developers.facebook.com/docs/whatsapp/cloud-api/get-started#sent-test-message
Enter the recipient phone number you would like to message in the To field. Ensure the number is correct, and that you want to add it to your list of 5 possible message recipients —as you add phone numbers, follow the prompts on the screen to verify you have access to them. Once this number has been added, it cannot be removed from your list.
Note: This limitation is only for WhatsApp-provided test phone numbers. Real phone numbers that you register do not have a limit on the number of recipients.
You don't need to register receivers' phone numbers if you are using your own real business phone number in the sender's phone number.
Imagine an iphone app that automatically registers users on the first start according to their phone identity (e.g. phone number*) on a server database.
Afterwards, users should see which of their friends already use the app, i.e. which of their contacts are registered on the DB.
An obvious solution would be to always send a select-request to the DB containing all of the users contacts, everytime the user refreshs his or her friend list. As a result, the user retrieves the list of their registered contacts (friends).
Is there any better way to realize this synchronization between the user management on the server and the contacts in the user's address book. Sending multiple select-requests (each user for every refresh) with dozens of phone numbers might not be performant at all.
Example:
WhatsApp is actually a good example for this scenario. You can add new contacts to your address book and WhatsApp automatically refreshs your WhatsApp friend list according to your phone book. I really like this idea because the user don't need to create an account manually.
*I know about the problems of using phone numbers in AppStore apps, so this question really focusses on the architectural problem.
EDIT
this comment (Whatsapp contacts syncronization) describes the mentioned simple approach. but is this really the smartest way?
I've noticed that my android phone, the iphone, outlook.com, and yahoo mail all can import my friends' email addresses (and sometimes phone numbers) from facebook. However, I don't see anywhere in the documentation of the API to suggest that you can get email.
Do these services have special agreements with Facebook or am I just not finding the specific api for "contact" importing? I've not had any luck using "email" field with friends api.
Any ideas?
These services have some special agreements with Facebook and thus are able to retrieve the Email Ids of the Friends of the User. Most of them don't allow further exporting of data obtained from there directly.
And as per Email Permissions documentation here it clearly states that for App Developers
Note: There is no way for apps to obtain email addresses for a user's friends.
As per the phone number, there is no access to it no matter what permission. You may though ask the user to fill those for you.
I'm doing estimates for a Windows 8 app, and I would like to programatically search the Windows 8 contacts store for a person's name based on their phone number or email address. Is this possible in WinRT/.Net? I can't seem to find documentation for an API to do this.
You can't do that per se. If you want to access the contacts locally, you have to use the Contact Picker Contract. That will bring up the People hub and let the user select one or more contacts that you can then operate on. If you want to search the user's contacts, you have to use the Live Connect APIs. Check out the Interactive SDK and this video from Build.
I am working on iphone application.I wanted to get the social networking (facebook,twitter, etc) profile details by giving email id as query. Is there any method to get the profile ?
For Facebook you can try this answer: https://stackoverflow.com/a/5247066/580173
For twitter this this not possible. You can use oAuth to authenticate the user and get the profile.
For LinkedIn I believe it's also not possible. LinkedIn doesn't communicate the emailaddress anywhere in their API.
See this forum post: https://developer.linkedin.com/thread/1131
I'm assuming that you're wanting to just add the social profile links to a user's profile inside your app...correct? (If you want to actually allow your users to post to their various social media accounts, your best bet is to go ahead and let users sign into each individual account via OAuth.)
If you're looking to get public social info via email address, your free options for a simple solution are pretty limited. Each different social network has its own method, so you'd need to build out a different process to query each social network you want to support. Without more info on which networks you want to support, there are any number of different answers to this question - so I'll just say your best bet is to check out the developer docs of whichever social networks you want to use.
If you're looking for a paid solution, you might try FullContact (full disclosure - I work for them). The Person API pretty much does exactly what you're looking for - pulling all public social media profiles associated with a particular email ID. API docs are here.
However, it is a paid solution, which may not be what you're after.
