Survicate Unity SDK

The Survicate Unity SDK will increase your APK size by approximately 2.5MB when obfuscated and your IPA size by approximately 2.2 MB. Note that the SDK features a Time To Live (TTL) mechanism of 60 seconds. This means any modifications made to your survey will be reflected on your respondents' devices after a delay of up to 60 seconds.

Define https://repo.survicate.com Maven repository in one of the following ways:

Add Survicate SDK dependency to your app's build.gradle file.

Legacy Configuration for Android

With the new approach, you no longer need to add the .aar file to your project or define transitive dependencies manually.

Show legacy configuration

Download the latest android SDK from here. Place the downloaded AAR file inside Assets/Plugins/Android
Make sure Android is selected as plugin platform on Inspector window
Add dependencies listed in developers documentations here
Configure your workspace key in AndroidManifest.xml file.

ProGuard / R8

When using Proguard or R8, add the following rules to your custom Proguard file.

Configuration for iOS

Add workspace key to your Info.plist file.
- Create Survicate Dictionary.
- Define WorkspaceKey String in Survicate Dictionary. Your Info.plist file should looks like this:
Run pod update in your ios directory.

Initialization

Initialize the SDK in your application using initializeSdk() method. Call this method only once, in the main script of your project.

Using SDK

Survicate allows you to launch precisely targeted surveys inside your app. In the Survicate Panel, you can set conditions that need to be met for the surveys to appear. Users matching conditions defined in the Survicate panel will see the survey automatically. Here's a list of conditions you can use to target your surveys:

Name of the screen that a user currently sees
Any application event
User attributes and identities
Language of the device
Operating system

Make sure to list all the screens and events described in your application. Once you got this covered, you or any person responsible for creating and managing surveys will be able to trigger surveys from the Survicate panel with no need for you to update the application.

Targeting a survey by screen name

A survey can appear when a user is viewing a specific screen. For example, a survey can be triggered to show up on the application's home screen after a user spends more than ten seconds there. To set it up, you need to send information to Survicate about the user entering and leaving a screen.

Note: Multiple active screens are allowed. In specific, calling EnterScreen() does not make the previous screen to be discarded. Be sure to call LeaveScreen() when you no longer want the screen to be treated as active.

Screen name is case sensitive. If there's any discrepancy between what's declared in the ‘Screens’ tab of the Target section in the Survicate panel and the application code, the survey will not appear.

Events-based survey targeting

The SDK allows you to launch surveys based on events your users trigger in your app. Your survey will show instantly after an event occurs in your app.

Event name and property keys are case sensitive. If there is any discrepancy between what's declared in the ‘Triggers’ tab of the Target section in the Survicate panel and the application code, the survey will not appear.

Passing user attributes

You can provide user attributes to Survicate as an extra layer of information about your users. The attributes have various use cases:

Identification of survey participants (answers are anonymous by default).
Directing surveys to particular users (Audience filters).
Filtering responses.
Recalling data in questions.

Bear in mind that user attributes are cached. You only need to provide them once, e.g. when user logs in, not after each initilization. You can also change their values at any time to trigger a survey.

Attribute types

string: any text.
int: an integer.
double: a decimal.
bool: a logic value.
DateTime: a Date object suitable for use with date or time interval Audience filters (the time interval filter measures elapsed time from a given timestamp).

Special attributes

user_id: This corresponds to the "Logged-in status" in the panel's Audience filter. A user is considered logged-in when a trait with the "user_id" key has been set on the device, regardless of the value.
first_name, last_name, email: If none of these is specified, a response will be marked as Anonymous in the panel.

Additional notes
You can set your own attribute keys without any prior registration. They will show up in the panel once any response with the attribute is uploaded.

Reseting user data for testing purposes

If you need to test surveys on your device, Reset() method might be helpful. This method will reset all user data stored on your device (survey views, attributes, information about answered surveys for the targeting engine).

Event listeners

SDK allows you to utilize event listeners. You may find them useful to trigger actions in your application based on actions performed by respondents. Here's a list of events you can subscribe to:

onSurveyDisplayed - occurs when survey is loaded and appears in the User Interface
onQuestionAnswered - occurs after a question is answered ( Survicate stores incomplete survey submissions )
onSurveyClosed - occurs when a user closes the survey using the close button
onSurveyCompleted - occurs when a user finishes the survey

SurvicateAnswer properties (QuestionAnsweredEvent.answer)

Property	Type	Description
type	string	Answer type. One of: ['text', 'single', 'multiple', 'smiley_scale', 'rating', 'csat', 'numerical_scale', 'nps', 'date', 'form', 'matrix', 'button_close', 'button_next', 'button_link'].
id	long?	Answer ID. Applicable only for types: ['single', 'smiley_scale', 'csat', 'rating', 'numerical_scale'].
ids	List<long>	Selected answer IDs. Applicable only for type = ['multiple'].
value	string	Text representation of an answer, e.g. "Happy" for smiley scale. A `null` value in case of a skipped question. Not applicable for call-to-action answers: ['button_close', 'button_next', 'button_link'].

The id, ids and value properties are provided only for the cases enlisted in the table above. Therefore, expect that there might be answer objects that consist only of the type property.
