Using the Twitter module you can let your application users connect themselves with Twitter. Additionally, you can create tweets, read your timeline and mentions and send/receive direct messages.

Twitter Module converted to Native Module

As of ApiOmat 2.6.0 this module is not a "Static Module" anymore, it is now delivered as Native Module. This transition have been made to offer you a more lean product which is extendable according to your individual needs. As our experience had shown that most of our customers do not need the Twitter module, we do not deliver it anymore by default and you can benefit from this save in space and memory. If you nevertheless need the Twitter Module on your installation, feel free to contact us.

Configuration

configuration key	description
Consumer Key	Consumer key of the Twitter app which you want to use to authenticate against.
Callback URL	Callback URL of the Twitter app which you want to use to forward after the App was authorized by the user.
Consumer Secret	Consumer secret of the Twitter app which you want to use to authenticate against.

More information can be found in the twitter docs.

Usage

After setting the configuration parameters, you may call the following URL in your app to start authentication for a user, replacing {YOURAPPNAME} with the name of your app. Note that you have to deliver the user credentials with basic auth in header and don't forget to add the 'X-apiomat-system' header with the system (LIVE/STAGING/TEST) to your request. If the header is not added, it will fallback to the LIVE system.

URL

https://{urlToYourInstallation}/yambas/rest/modules/Twitter/{YOURAPPNAME}/spec/auth

The user is presented the Twitter site asking if the requesting app (with the ID set in the configuration) may be used to authenticate them. If the user clicks OK the authentication starts, otherwise it is cancelled.

If authentication was successful, the user object will have three values set on the dynamicAttributes map on the users object on server side: twitterOAuthToken, twitterOAuthVerifier and twitterOAuthSecret. To fetch these you have to do a simple reload of the user, so your code may look like this:

Android

Android

callAuthURL();
// do other things
 
// later on get the actualized user object
user.loadMeAsync(new AOMEmptyCallback() {
 
	@Override
	public void isDone(boolean wasLoadedFromStorage, ApiomatRequestException exception) {
		if (exception != null){
			System.out.println("Auth code: " + user.getDynamicAttributes().get("oAuthToken"));
		}
	}
});

Objective-C

Objective-C

callAuthURL();
// do other things
 
// later on get the actualized user object
[user loadMe:^(NSError * error) {
        NSLog(@"Auth code: %@", [user getOAuthToken]);
}];

Swift

Swift

callAuthURL();
// do other things
 
// later on get the actualized user object
user.loadMe { (error) in
       
}

JavaScript

JavaScript

var user= new Apiomat.User();
 
callAuthUrl();
 
user.loadMe({
    onOk : function() {
        console.log("oAuthToken: " + user.data["dynamicAttributes"]["oAuthToken"]);
    },
    onError : function(error) {
    }
});

Using these values you can access Twitter API without doing a rather complicated OAuth handshake by yourself.

			// ...
		}
	}

Native Module related changes and update process

As of ApiOmat 2.6.0 this module is not a "Static Module" anymore, it is now delivered as Native Module. These transitions have been made to offer you a more lean product which is extendable according to your individual needs. As our experience has shown that most of our customers do not need the Twitter module, we do not deliver it anymore by default and you can benefit from this save in space and memory. If you nevertheless need the Twitter Module on your installation, feel free to contact us.

If you upgrade to ApiOmat 2.6.0, it will automatically detect whether the module is used in other modules or in a backend on your installation and will then be converted to a dynamic module with any of the classes, which can be seen as a placeholder. As it is just a placeholder, it does not include the logic and you have to upload it as native module with the SuperAdmin account nevertheless. If it is not used by any backend or any module, it will simply be deleted and you can upload it with any user you want.

Potentially breaking changes and improvements

We list the changes that had been made in comparison to the static module here. These changes may need your interaction if you already use the module

The reference field directMessages in class DirectMessage does not return instances of Tweet anymore. Instead it will return the correct DirectMessage class.
DirectMessage objects will not be stored partially in the MongoDB, instead they are now fully transient. Therefore they have no MongoDB ObjectID anymore and are now identified directly by its ID from Twitter.
In the static module you had to create instances of DirectMessages and Timeline and persist them to get the direct messages and timeline tweets and mentions. These objects are not persisted anymore.
The "auth" REST endpoint had changed:
- The name of the backend is now after the "Twitter" and before "spec" part of the url
- The endpoint does not take memberId or userId and the usedSystem as query parameter anymore, instead this information will be taken from the authorization header and the x-apiomat-system header from your request. This also means, that you don't have to find out the id of the User object and can instead simply use its userName
The user object does not have the getters and setters for the OAuth token, secret and verifier anymore. You have to get these values over the dynamicAttributes map stored on the user.
The keys "oauthToken", "oAuthSecret" and "oAuthVerifier" in the dynamicAttributes-Map that are stored after authorization, have been renamed to "twitterOAuthToken", "twitterOAuthSecret" and "twitterOAuthVerifier".
