+### Webhook types
+
+A [webhook](https://dev.fingerprint.com/reference/posteventwebhook) sent by Fingerprint has the same shape as an `Event`. You can deserialize the payload directly into that type using the SDK's own JSON mapper:
+
+```java
+import com.fingerprint.v4.model.Event;
+import com.fingerprint.v4.sdk.JSON;
+
+Event event = JSON.getDefault().getMapper().readValue(webhook, Event.class);
+System.out.println(event.getIdentification().getVisitorId());
+```
+
+### Webhook signature validation
 This SDK provides utility method for verifying the HMAC signature of the incoming webhook request.
 
 Here is an example implementation using Spring Boot:

+### Updating the codegen engine and templates
+
+The generator version is pinned as the `openapi` entry in [gradle/libs.versions.toml](./gradle/libs.versions.toml). To update it:
+
+1. Bump the `openapi` version in that file.
+2. Compare each file in [template](./template) against the matching upstream `java` or `jersey3` generator template at the new version, and merge in any upstream changes the same way you would resolve a merge conflict.
+3. Update the engine and the templates in the same change. Using the new engine with old templates, or the other way around, can break code generation without a clear error.

 ## Testing the local source code of the SDK
 
 Use the [./src/examples/java/com/fingerprint/example/FunctionalTests.java](./src/examples/java/com/fingerprint/example/FunctionalTests.java) file to make API requests using the local version of the SDK.
