Change of Endpoints to fetch Crashlytics Settings

[imran-samed7]

Is it possible to change the endpoints to fetch Crashlytics settings in the Android SDK when using Crashlytics?

We are utilizing IoT SIMs on our devices, and the *.crashlytics.com API is not allowed with our SIM, while *.googleapis.com is permitted. Is there an API available that allows me to modify the endpoints to retrieve crashlytics settings?
or some pre-defined settings, which I can store locally in the project and inject while initiating Crashlytics APIs.

Or is there any exposed REST API to push/pull crashlytics Data ?

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

[imran-samed7]

@lehcar09 Is it possible to keep the initial data needed by Crashlytics in the google-services.json file itself?
If so, please assist me with this. Alternatively, is there another way to skip the initial settings fetch and add data locally?

[imran-samed7]

@lehcar09 can anyone else help on this? This is urgent.

[imran-samed7]

@cherylEnkidu @sheepmaster @dlackty
Kindly help with this.

[sheepmaster]

@imran-samed7 I'm flattered that you are tagging me for help with this, but I have not been on Firebase (or working at Google, for that matter) for quite some time now.

[lehcar09]

Hi @imran-samed7, thank you for reaching out. Currently, there is no API that allows users to modify the endpoints to retrieve the Crashlytics settings. Nor REST API where you can pull these data.

We recommend whitelisting the ff. Endpoints for Crashlytics:

*.crashlytics.com
crashlyticsreports-pa.googleapis.com
firebasecrashlyticssymbols.googleapis.com

I'll mark this as a feature request. However, we are unable to promise any timeline for this, we'll definitely keep this under our radar.

P.S. For folks who find this useful, adding an emoji thumbs up on the original post can help us prioritize adding this to the roadmap.
