Searching for an excellent career in Oauth? we are here to help you with your Oauth job interview. The questions listed by wisdom jobs experts are the most commonly asked, as they will give a recruiting manager an idea of your background, experience, abilities, strengths, and weaknesses. OAuth is a protocol that authorizes an application or a third-party website to process a user's data without the user knowledge to share login credentials. There are many OAuth jobs available in top organizations for different positions in the market, in popular cities in India. For more details please visit our Oauth job interview questions and answers page where you can see some sample questions in an Oauth job interview along with some tips to follow before an interview.
Question 1. How Is Authentication Handled With G Suite?
Answer :
We use OAuth 2.0 in order to authenticate to G Suite accounts for all Google services. This includes email, contacts, calendars, and documents under Google Drive.
Question 2. What Type Of Accounts Can Use Oauth 2.0?
Answer :
Note: Previously, OAuth 1.0 was only available to paid G Suite accounts, namely G Suite for Business and Education.
Question 3. How Do I Migrate Using Oauth 2.0 With Administrative Authentication?
Answer :
Follow the directions in the Knowledge Base article KB005019 to set up the G Suite account to use OAuth 2.0. In order to provide us administrative authentication access to your G Suite data, add certain allowed scopes to the MigrationWiz project, as described in the article. Also, the article shows how to enable API access, which is required for performing a Google Drive migration.
Question 4. What If I Want To Run A Migration On A G Suite Account Without Adding Oauth Credentials?
Answer :
If not using administrative authentication, then an OAuth 2.0 challenge requires user actions in order to authorize MigrationWiz to access their data. After submitting a migration for mailbox(es), MigrationWiz will send an email to each user mailbox in order to ask for access privileges. Once the user confirms access privileges, their migration will begin.
Note:
Here are some more generic (non-specific to MigrationWiz) questions and answers about OAuth and OAuth 2.0. These have been included here to provide some more detail about how it works.
Answer :
OAuth is an open standard for authorization. OAuth provides client applications a 'secure delegated access' to server resources on behalf of a resource owner. It specifies a process for resource owners to authorize third-party access to their server resources without sharing their credentials. Designed specifically to work with Hypertext Transfer Protocol (HTTP), OAuth essentially allows access tokens to be issued to third-party clients by an authorization server, with the approval of the resource owner, or end user.
The client then uses the access token to access the protected resources hosted by the resource server. OAuth is commonly used as a way for web surfers to log into third-party web sites using their Google, Facebook or Twitter accounts, without worrying about their access credentials being compromised.
Question 6. How Does Oauth 2.0 Work?
Answer :
To access protected data stored on Google services, use OAuth 2.0 for authorization. Google APIs support OAuth 2.0 flows for different types of client applications. In all of these flows, the client application requests an access token that is associated with only the client application and the owner of the protected data being accessed. The access token is also associated with a limited scope that defines the kind of data the client application has access to (for example, "Manage your tasks"). An important goal for OAuth 2.0 is to provide secure and convenient access to the protected data, while minimizing the potential impact if an access token is stolen.
The typical work flow for OAuth 2.0 requests:
Answer :
No. The OAuth 2.0 Authentication Management API may only be used with RESTful APIs provided by AT&T.
Question 8. Is Notary Management Restricted To The Payment Api?
Answer :
Notary Management can be used with any other API and is not restricted to the Payment API, OAuth, or any other API. However, if the Payment API is used, the Notary service must be used to facilitate those APIs.
Question 9. Do I Have To Create An Oauth Access Token Every Time I Need To Access A Resource?
Answer :
No. An OAuth access token can be used until it expires.
Question 10. How Does Openid Differ From The Oauth 2.0 Authentication Management Api?
Answer :
OpenID is about authentication (i.e. proving who you are). OAuth is about authorization (i.e. granting access to functionality, data, etc., without dealing with the original authentication).
Question 11. Does The Oauth Access Token Expire?
Answer :
After the lifetime that is specified in the expires_in parameter has elapsed, the OAuth access token is no longer valid. When that occurs, any attempt to use the expired OAuth access token results in an OAuth 2.0 Authentication Management API response with the HTTP Status Code of 401 Unauthorized. A developer must provide logic in their app to handle conditions when the expired OAuth access token may be used.
Question 12. What Is The Class 'definition Not Found' Error In Android Sample Apps?
Answer :
This error occurs because the SDK jar file is not added to the application. Steps to fix this issue:
Question 13. Are All Apis Available With Premium Access?
Answer :
Most APIs are available, but some may have additional requirements such as:
You can find out more information for specific APIs by visiting our pricing page and clicking on the API you are interested in.
Question 14. Does The Speech Api Only Work On At&t Wireless Mobile Devices?
Answer :
The Speech API, including the Speech-to-Text transcription and Text-to-Speech functionality, is offered as a RESTful API that runs on the AT&T platform. This means that the API can be used from almost any mobile device, including those using other U.S. wireless carriers and on non-mobile devices, such as backend applications running on servers.
Answer :
Yes, you can stream (chunk) audio data as input. There is no need to record the audio first.
Question 16. What Do I Need To Know About Oauth?
Answer :
Applications must always use an OAuth token in the API request header called Authorization: in order to consume any of the APIs provided by AT&T.
An OAuth access token is obtained by invoking the OAuth API which triggers the authorization process. This process may involve interaction between the application and the API Platform only, as in the case of OAuth Token request, or it may involve interaction between the user's browser and the API platform. In the latter case, the secure interaction is initiated by the developer's application but the secure authentication is intentionally routed around the developer's application and, in so doing, assures the end-user that their user credentials are kept secure and are only passed between AT&T and the user's browser.
Question 17. Why Should I Use The Oauth 2.0 Authentication Management Api?
Answer :
The OAuth 2.0 Authentication Management API is more secure than the typical user name and password paradigm as the credentials are not stored on the mobile device.
Question 18. What Is An Aap (application Authentication Package)?
Answer :
The AAP (Application Authentication Package) bundle is a zip file that contains resource files including your Application Certificate and your Developer Key. The resource files differ depending on whether your app is certified for a development environment or a production environment. After you submit your app information to the AT&T Launch Center, development resource files will be available in your developer dashboard, and after your app passes AT&T Quality Engineering testing, production resource files will be available.
Question 19. How Do I Add A Device To My Receiver?
Answer :
To add a device to your receiver, you must have the AT&T U-verse Enabled Application installed on your device. Launch the application on your device and navigate to the U-verse Receivers screen. The process below is based on an application that follows the U-verse End User Design Guidelines.
If the receiver name appears in the list with no icons next to it, which is when the receiver is in open mode, select it to connect your device to that receiver and start using the application. No additional action is needed. If the receiver name displays a lock icon pictured next to it, which is when the receiver is in custom/managed mode, you will need to enter a four digit PIN on your device to connect:
You should see the receiver is now unlocked. If you don't see the receiver name on your device, tune to channel 9301 on that TV receiver, select +Add New Receiver on your device and follow the instructions to run the Set-up Wizard.
Question 20. What Do I Do If I See "internal Error Code 3000"?
Answer :
This normally indicates that the AAP is not valid. If you receive this error, please check that you are using the correct AAP bundle for your test environment.
Question 21. Do I Need To Have An App Key, App Secret, And Short Code To Run The Sdk Sample Apps?
Answer :
Yes, to run the SDK Sample Apps you must first create a new app in My Apps to acquire an App Key and App Secret.
The short code is optional. It is only needed by SDKs that require AT&T Wireless customer consent to allow the apps to use the customer’s AT&T Wireless mobile number.
Question 22. How Do I Start Discovery?
Answer :
Using the shared instance of Uverse Connected Manager, call the start Discovery method on application load to initiate the discovery process:
iOS
[[UverseConnectedManager sharedManager] startDiscovery];
Android
uveManagerInstance.startDiscovery(uveListenerInstance);
Question 23. How Should I Access A Reference To The Current 'settopbox'?
Answer :
We recommend using mostRecentlyEngagedSetTopBox property of uverseConnectedManager, as this will be updated each time the user engages a different receiver. For example, to get the current channel details of the currently displayed program:
iOS
UverseConnectedManager *manager = [UverseConnectedManager sharedManager];.
NSString *channel = manager.mostRecentlyEngagedSetTopBox.currentProgram.channel;.
Android
uveManager manager = uveManager.getUverseEnabledManager(this,null,AAP_FILE_NAME, RESOURCE_TOKEN);
manager.getMostRecentlyEngagedSetTopBox();
Question 24. What Platforms Are Supported In U-verse Enabled?
Answer :
iOS and Android are the platforms currently supported.
Question 25. What Are The Different Types Of Aaps?
Answer :
There are two different types of AAP (Application Authentication Package) bundles that could be issued:
Question 26. What Should I Do If The 'uverseconnectedmanager' Initialization Fails?
Answer :
The UverseConnectedManager initialization will fail if you are not on a U-verse network. You must be connected over Wi-Fi to the same access point as the receiver. If it fails for other reasons, you may use the upload log function, or try again (call startDiscovery again). Ideally, if you are on the Wi-Fi of a U-verse household, discovery should not fail.
Answer :
No. You must use AT&T's OAuth service to use any of AT&T's APIs.
Question 28. What Operating Systems Support The At&t Aro Data Analyzer?
Answer :
The AT&T ARO Data Analyzer is supported on Microsoft Windows XP, Windows Vista, Windows Seven, Windows 8 (x86), and on Mac OS X 10.6 and above, including MAC OS X 10.10.
Answer :
The AT&T implementation is generally consistent with the OAuth 2.0 Draft 13 framework. However, there are several nuances to the AT&T implementation, such as the use of commas instead of spaces to delineate parameters within the scope variable.
Question 30. How Do I Handle Tokens That Have Expired?
Answer :
The two complimentary strategies that developers may consider when handling expired tokens are as follows:
Capture the response with the HTTP Status code of 401 Unauthorized and invoke logic that retries the appropriate Get Access Token method request, as follows:
In the future, AT&T may change the default values of the expiration parameters for the OAuth access token and refresh token. So it is strongly advised that you always check the expires_in parameter value that is returned with the response to the Get Access Token method call.
Answer :
The URL that you use in your requests must either be an exact match to the OAuth Redirect URI in your application on the AT&T Developer Program website or be an extension of that value. The Redirect URI uses the following rules:
