# OkHttp Upgrade

To mitigate security risks in OkHttp 3.x, starting from version 3.2.0, the OkHttp dependency is upgraded from 3.12.13 to 4.12.0.

### Roll back to OkHttp 3.12.13

If the upgrade conflicts with your project, you can explicitly declare the following dependencies in your application's `pom.xml` to roll back. Per Maven's "nearest definition" dependency mediation rule, the version declared by the application will override the 4.12.0 transitively introduced by the SDK:

```xml
<dependency>
<groupId>com.squareup.okhttp3</groupId>
<artifactId>okhttp</artifactId>
<version>3.12.13</version>
</dependency>
<dependency>
<groupId>com.squareup.okhttp3</groupId>
<artifactId>logging-interceptor</artifactId>
<version>3.12.13</version>
</dependency>
```

> **Note**: Rolling back will reintroduce the security risks fixed in newer OkHttp versions. Use it only for emergency troubleshooting and issue diagnosis, and restore OkHttp 4 as soon as the issue is resolved.
