+### How to use undocumented parameters and properties
+
+In some cases, you might encounter parameters on an API request or fields on an API response that aren’t available in the SDKs.
+This might happen when they’re undocumented or when they’re in preview and you aren’t using a preview SDK. 
+See [undocumented params and properties](https://docs.stripe.com/sdks/server-side?lang=php#undocumented-params-and-fields) to send those parameters or access those fields.

 ### Public Preview SDKs
 
 Stripe has features in the [public preview phase](https://docs.stripe.com/release-phases) that can be accessed via versions of this package that have the `-beta.X` suffix like `12.2.0-beta.2`.
 We would love for you to try these as we incrementally release new features and improve them based on your feedback.
 
-The public preview SDKs are a different version of the same package as the stable SDKs. These versions are appended with `-beta.X` such as `15.0.0-beta.1`. To install, choose the version that includes support for the preview feature you are interested in by reviewing the [releases page](https://github.com/stripe/stripe-dotnet/releases/) and then use it in the `composer require` command:

+### Private Preview SDKs
+
+Stripe has features in the [private preview phase](https://docs.stripe.com/release-phases) that can be accessed via versions of this package that have the `-alpha.X` suffix like `12.2.0-alpha.2`. These are invite-only features. Once invited, you can install the private preview SDKs by following the same instructions as for the [public preview SDKs](https://github.com/stripe/stripe-php?tab=readme-ov-file#public-preview-sdks) above and replacing the term `beta` with `alpha`.
+
 ### Custom requests
 
+> This feature is only available from version 16 of this SDK.
+
 If you would like to send a request to an undocumented API (for example you are in a private beta), or if you prefer to bypass the method definitions in the library and specify your request details directly, you can use the `rawRequest` method on the StripeClient.
