    • language: Accepted languages: de-de, en-au, en-ca, en-gb, en-in, en-us, es-es, es-mx, es-us, fr-ca, fr-fr, fr-br (case sensitive). Default to the device's locale language.
    • sessionUid: Value to track each session of inBrain use from a specific userID
    • isS2S: If the SDK runs in Server To Server mode. Default false
    • userId: The unique string value that differentiates each user within their app when initializing inBrain (Example: an email, a username). Default ''
    • title: The surveys view title. Default ' Surveys'
    • navigationBar: The navigation bar configuration

Note: This method need to be called prior calling all the other methods.

Change the session parameters

inbrain.setSessionParameters(sessionUid: string, dataPoints: {}) : Promise<void>
  • sessionUid the session identifiers
  • dataPoints datapoints

Show the surveys webview

inbrain.showSurveys() : Promise<void>

Get the rewards (Useful for server less app)

inbrain.getRewards() : Promise<InBrainReward[]>

Confirm a list of rewards (Useful for server less app)

inbrain.confirmRewards(rewards: InBrainReward[]) : Promise<void>
  • rewards: List of rewards to confirm

Check if Native Surveys are available

inbrain.checkSurveysAvailable() : Promise<boolean>

Get the Native Surveys available

inbrain.getNativeSurveys(placementId?: string) : Promise<InBrainNativeSurveys[]>
  • placementId: an optional placement identifier

Show a Native Survey

inbrain.showNativeSurvey(id: string, placementId?: string) : Promise<void>
  • placementId: an optional placement identifier

On webview dismissed

inbrain.setOnCloseListener(callback: () => void) 
  • callback: callback to perform when it happens

Note: Calling this method multiple times will override the previous listener.

On webview dismissed from page

[BUILD TIME] Several errors similar to Bad receiver 'int *', Unkown type name 'InBrain'...

First check that the framework target membership is correctly set. If the problem still occurs, and you are trying to create a release build with a simulator as target (and you are using XCode 12), please add arm64 in the Excluded Architecture of your project and 'inbrain-surveys' pods (see this post for detailed information)

[RUNTIME] Library not loaded: @rpath/libswiftCore.dylib

This problem can happen if your project doesn't have the Swift standard libraries included. Set the 'Always Embed Swift Standard Libraries' to yes in your target to fix it. Clean and build the project after changes. This problem also consistently appears when usinx XCode10

[RUNTIME - Release scheme] dependent dylib '@rpath/InBrainSurveys_SDK_Swift.framework/InBrainSurveys_SDK_Swift' not found

This problem happen with previous version of Cocoapods and XCode. Try updating to Cocoapods 1.10.x, and if it still doesn't work, also upgrade to XCode12

[DEVELOPMENT] When running 'pod install' in APP: "Specs satisfying the inbrain-surveys (from ../node_modules/inbrain-surveys) dependency were found, but they required a higher minimum deployment target."

=> Modify the platform version in 'APP/ios/Podfile'

[DEVELOPMENT] When building in XCode: No matching function for call to 'RCTBridgeModuleNameForClass'

Update from RN0.62 to RN0.63

[DEVELOPMENT] When building in XCode: problem with not finding switch libraries
