Flex Gateway Policy Development Kit (PDK) provides example policy projects to get started configuring your Rust source code.

Find all policy examples and their documentation in the PDK Custom Policy GitHub Repository.

PDK offers the following example policies:

Certification Policy Example: Use the Certification Policy as an example of how to obtain data concerning connection certificates.
Crypto Policy Example: Use the Crypto Policy as an example of how to use third-party libraries that provide cryptography capabilities in your custom policy.
Data Caching Policy Example: Use the Data Caching Policy as an example of how to implement data caching in your custom policy.
JWT Validation Policy Example: Use the JWT Validation Policy as an example of how to use functions of the JWT Library in your custom policy.
Simple OAuth 2.0 Validation Policy Example: Use the Simple OAuth 2.0 Validation Policy as an example of how to implement HTTP calls in your custom policy.
Query Policy Example: Use the Query Policy as an example of how to handle DataWeave expressions in your custom policy.

Set Up an Example Policy Project

To begin using an example policy project:

Ensure you have installed all the PDK prerequisites.
Clone the PDK Custom Policy GitHub Repository with the following command or your preferred GitHub interface:
```
git clone https://github.com/mulesoft/pdk-custom-policy-examples.git
```
Navigate to the newly cloned directory, then copy and paste the directory of your desired policy into a new location.
In the cargo.toml file of the copied policy example, replace the group-id with your group ID, for example:
```
group_id = "<your-group-id>"
```
Run the make setup command.
```
make setup
```
Navigate to the README.md file in the example policy to read more about the policy and how to test it.
