Retrieving Instance ID token or FIS auth token for setting up A/B testing device

[lpatino10]

Hi everyone!

I've been using this library for a while to work with Remote Config and for setting up A/B tests. I recently found out that you can add a test device to an experiment to programmatically target variants as a sanity check before starting the experiment. See here for reference.

The Firebase UI is asking for an "Instance ID token or FIS auth token". I've tried pasting in the value I get from all of the following API methods, but in every case Firebase is telling me that the token is invalid:

• analytics().getAppInstanceId()
• app.options.appId
• app.options.apiKey
• app.options.gaTrackingId
• app.options.messagingSenderId

Does anyone know what the right method might be, or if this is just unsupported in this library? For reference, I'm using SDK version 11.4.1 and I'm trying to test this on the Android emulator.

Thanks!

I think what you want is messaging.getToken() ?
