+# API-Key restrictions may need to be updated with new version of Firebase iOS SDKs.
+
+## What happened?
+
+The following SDKs updates introduce a dependency on the [Firebase Installations API](https://pantheon.corp.google.com/apis/library/firebaseinstallations.googleapis.com), a new infrastructure service for Firebase:
+
+- Analytics
+- Cloud Messaging
+- Remote Config
+- In-App Messaging
+- A/B Testing
+- Performance Monitoring
+- ML Kit
+- Instance ID
+
+
+As a result, API restrictions you may have applied to API keys used by your Firebase applications may have to be updated to allow your apps to call the Firebase Installations API.
+
+## What do I need to do?
+
+Before upgrading your application(s) to the latest SDK version, please **make sure that the API key(s) used in your application(s) are whitelisted for the Firebase Installations API:**
+
+- **Open** the [Google Cloud Platform Console](https://pantheon.corp.google.com/apis/credentials?folder).
+- **Choose** the project you use for your application(s).
+- **Open**  APIs & Services and **select** Credentials.
+- **Click** Edit API Key (pencil icon) for the API key in question.
+- **Scroll down** to the API restrictions section.
+- If the radio button shows Don't restrict key, the API key is not affected.
+Otherwise, from the dropdown menu, **add** the  Firebase Installations API to the list of permitted APIs, and click Save.

+- [added] The Firebase Installations SDK introduces the Firebase Installations API. Developers that use API-restrictions for their API-Key may experience blocked requests (https://stackoverflow.com/questions/58495985/).
