Can I override CI Environment Variable via Bitrise API? I saw Bitrise Swagger API Document, I couldn’t find how to override Environemnt Variables, except `POST: /apps/{app-slug}/bitrise.yml`. But our `bitrise.yml` is very huge file so it’s difficult to post after converting bitrise.yml into one string value. If you have some solutions, can you tell me the solutions?

Hey @funzin, It’s not possible currently to set environment variables via the API. Can you describe your use case in more detail? ---

Apple started 2FA mandatory and so we have changed to use AppStoreConnectAPI instead of FASTLANE\_SESSION. FASTLANE\_SESSION is required for some(e.g.AppStoreConnectAPI doesn’t support upload / download dsyms fastlane actions.) Now, I change FASTLANE\_SESSION manually on Bitrise, but I wanna change it through using Bitrise API ---

We have a page [summarizing various steps and their possible authentication methods](https://devcenter.bitrise.io/getting-started/configuring-bitrise-steps-that-require-apple-developer-account-data/#fastlane-step). Are you sure your use case is not covered by these options? ---

It didn’t work when I set it before so I think we should set `FASTLANE_SESSION` manually. But I just confirmed [summarizing various steps and their possible authentication methods](https://devcenter.bitrise.io/getting-started/configuring-bitrise-steps-that-require-apple-developer-account-data/#fastlane-step), `Assigning Apple ID authentication to your app` wasn’t set for some reason🤦‍♂️ Can I set it and check if there is no problem next week? If it occurs problem, I will ask you that again. ---

I confirmed correct behavior! ---
