5. Data Plugs

Data Plugs
In the HAT ecosystem, a Data Plug aka Data Plugin is a minimal API-to-API web service with the primary purpose of fetching data from 3rd party API and pushing it to an individual’s PDA. Due to the security considerations and limited scope of required functionality, each data plug is granted a write-only access to any particular PDA.
Fetch Data Plugs and Applications
HAT API Android provides an API call for you to fetch all the available Data Plugs:
HATExternalAppsService().getExternalApps(
            userToken: userToken,
            userDomain: userDomain,
            completion: availablePlugsReceived,
            failCallBack: errorRetrievingDataPlugs)
As you would have probably noticed, the function name is getExternalApps. Applications and Data Plugs are not only represented by the same structure but they have the same API as well.
userToken is the user's token to authenticate with the PDA
userDomain is the user's PDA address used to form the url to fetch the Data Plugs
completion is a callback function that is used when the request is successful with a type of ((List<HATApplicationObject>, String?) -> Unit).
The first parameter is an array of HATApplicationObject. This is the structure of Data Plugs and Applications. More on that in the next section.
This array contains all the Data Plugs and Applications on the PDA. The second parameter is an optional String, the refreshed user token that the PDA returns.
failCallBack is a callback that is used when the request has failed. The type of the function is ((HATError) -> Unit). HATErroris a custom object describing the errors that have occurred during the querying of the tables in the database.
A successful response will have statusCode 200 and look like this:

application holds the most parts of the structure. It consists of the following 7 values: 
1.id in the application part of the JSON is the id value of the Data Plug in the HAT. 
2.kind in the application part of the JSON has 4 values holding the various urls and the type of the Data Plug: 
1.url is the url of the Data Plug or Application to use in web 
2.iosUrl is the iTunes url of the Application in the App Store. It's optional and only there for Application type 
3.androidUrl is the Play Store url of the Application in the Play Store. It's optional and only there for Application type 
4.kind is the kind. As we mentioned earlier, Data Plug and Application is represented by the same structure and use the same APIs. 
Therefore, the kind can be App or Data Plug. When for example you want only the Applications then simply you are going to filter the array based on the kind.
3.info in the application part of the JSON has 12 values: 
1.version is the app's version number in the PDA. This may be different from the version number of the Application in the App Store or Play Store 
2.updateNotes is essentially the release notes for the latest version. It is formed by the header, the title of the release notes, and the notes, an array of String to easily show the notes as an unordered list.
3.published indicates if the app is published or not. It can be that the app is not yet published, so it's not yet live, and it's a testing, beta, app.
4.name is the official name of the app.
5.headline is the headline or subtitle of the app. It can be placed underneath the name, for example, to provide more context for the app if needed.
6.description allows you to describe your app better with a longer text. Also, it has support for different formats of text, text, markdown and html.
7.termsUrl is a URL for the terms and conditions. Users must be able to read them if they wish.
8.dataUsePurpose is a text explaining why and how the app will use the data.
9.supportContact a support email. Users will use this email to contact you.
10.rating is an optional object formed by score which describes the permissions and the data use using a letter-based scoring system. You can read more here.
11.dataPreview is actually an array of SheFeed structures. This is used to preview items, if any, instead of making another network request to fetch those items. The array can be empty.
12.graphics is a structure formed by 3 values: 
1.banner is the URL of the banner image. 
2.logo is the URL of the app logo image. 
3.screenshots is the URL of the app's screenshots used to showcase what this app offers.
All the above 3 values use the same structure. PDA images can be categorised as small, normal, large and xlarge. Except normal all are optional values.
4.developer consists of some basic info about the developer. This includes: id, name, url and country.
5.permissions includes 3 values: 
1.rolesGranted which is an array of role and detail describing the roles granted in the Application. 
2.dataRetrieved which is a type of DataOfferRequiredDataDefinitionObjectV2 but it's out of the scope of this guide. It describes the data that the Application will retrieve.
3.dataRequired which is a type of HATExternalAppsDataRequiredObject but it's out of the scope of this guide. It describes the data the Application requires.
6.setup encapsulates all the urls that the Application needs in order to setup. The structure is the same as kind but the url's can be different.
7.status provides some info about the status of the application:
1.compatibility is the last version that is compatible with the current one.
2.versionReleaseDate is the date, in ISO format, of the latest release.
3.kind the kind of the release. It can be either Internal or External.
setup is Boolean value indicating if this app has been setup successfully
enabled is Boolean value indicating if this app has been enabled successfully
active is Boolean value indicating if this app is currently active or not
needsUpdating is Boolean value indicating if this app needs updating. An Application may need an update in case the terms have changed or a new version has been released.
A request that has failed will look like this:
{
  "error": "Not Authenticated",

Set up Application
Setting up an application is similar to the login process. First you have to check the kind ; is it App, or Data Plug. The 2 are different in how you set them up:
In the case of an App you first have to check if the app is already installed on the user's device. You can check with:
Patterns.WEB_URL.matcher(appURL).matches()
where appURL is the androidUrl from the Application -> setup. If the user has the app installed, then you have to form a URL like this:
"https://$hatAddress/#/hatlogin?name=$appID&redirect=$appURL&fallback=$fallback"
hatAddress is the PDA's (fully qualified domain) address, e.g. postman.hubat.net
appID is the id of the application to setup.
appURL is the URL to which the user should be sent after completing authentication. In this case it is the androidUrl.
fallback is the URL to which the user should be sent in case the authentication has failed. Optional. For an Androidapplication that would probably be: $applicationName://failed and has to be added in the AndroidManifest file of the project in xml as a data scheme.
As you may have noticed this is exactly the same URL as the login URL; there is a reason for this. The setup process goes through the web. Just like during the login process, the user will be asked to insert their password before continuing to the next step. The next step is accepting the terms and conditions and giving the permissions the app requires to function. If everything goes smoothly, PDA will redirect back to the success redirect. The redirect url will now include a parameter which is the token for the particular app. Android will ask the user if they want to launch the particular app. If the user selects 'yes' then the app will be launched. If there is a problem, PDA will redirect to the fallback url and you have to hide Chrome and show a message that tells the user something has gone wrong.
If you don't know how to handle WebView, you can read here.
If the user does not have the app installed, you first have to redirect them to the Google Play Store so they can download the app. The URL to use is the url in Application -> kind. Again the only thing you have to do is open it using the browser. When user has installed the app they may then tap again to set up the Application.
Set up Data Plug
Setting up a Data Plug is a lot simpler than setting up an Application. You just open the url in Application -> kind with a browser and follow the instructions. Again, the user will first have to enter the password. After that each Data Plug has a different way of asking permissions and registering with the PDA.
State of the Application and Data Plug
Application and Data Plug can be in multiple states: Setup, failing, need updating, disabled. To respond in state changes you can use the following snippet:
/**
     Returns a ApplicationConnectionState according to the application state
​
     — parameter application: The application to check the state of
​
     — returns: An ApplicationConnectionState case depending in the status of the app
     */
     fun getState(application : HATApplicationObject) : ApplicationConnectionState {
         return if (applcation.setup && applcation.needsUpdating != null && applcation.needsUpdating!!) {
             ApplicationConnectionState.Update
         } else if (applcation.enabled && !applcation.active) {
             ApplicationConnectionState.Failing
         } else if (applcation.enabled && applcation.active) {
             if(applcation.mostRecentData != null)
                 ApplicationConnectionState.Running
             else
                 ApplicationConnectionState.Fetching
         } else {
             ApplicationConnectionState.Untouched
         }
     }
​
    enum class ApplicationConnectionState{
      Update,
      Failing,
      Running,
      Fetching,
      Untouched
    }
Running is  when the Application or Data Plug is enabled, active and doesn't needsUpdating
Fetching is when the Application or Data Plug is enabled, active, it's an App and the mostRecentData is null. This means that no data have yet been saved in the PDA.
Update is when the Application or Data Plug is marked as needsUpdating in the API response. This means the user has to go through the setup process again.
Failing is when there is a problem in the Application or Data Plug. Setting up again might or might not help. If this persists please contact us: [email protected].
Untouched is when the Application or Data Plug has never been setup before
Disable Data Plug or Application
You can also disable a Data Plug or an Application. To do that you can call the next function:
HATExternalAppsService().disableApplication(
      userToken: userToken,
      userDomain: hatAddress,
      appID: selectedApp.application.id,
      completion: appDisabled,
      failCallBack: errorDisablingApp)
appID is the id, in Application structure, of the Application or Data Plug
userDomain is the user's HAT address used to form the url to disable the Data Plug or Application
userToken is the user's token to authenticate with the PDA
completion is a callback function that is used when the request is successful with a type of ((HATApplicationObject, String?) -> Unit).
The first parameter is the disabled HATApplicationObject. The second parameter is an optional String, the refreshed user token that the PDA returns.
failCallBack is a callback that is used when the request has failed. The type of the function is ((HATError) -> Unit). HATErroris a custom object describing the errors that have occurred during the querying of the tables in the database.
A successful response will have statusCode 201 and look like this:
