You are free to use each operation (HTTP method) as you wish.

**FastAPI** doesn't enforce any specific meaning.

The information here is presented as a guideline, not a requirement.

For example, when using GraphQL you normally perform all the actions using only `POST` operations.

## Making your change

### Code change guidelines

Code contributions should follow these guidelines to maximize the chance of them being accepted:

* Cover your code with tests. See the [Testing guide](contributing/Testing.md) for more information.

## Log Message Guidelines

- Logger: `LogManager.getLogger(ClassName.class)`
- Format: `key=value` (e.g., `userId={}`, `url={}`)
- Prefix with `[name]` when context identification is needed
- Mask sensitive values (passwords, tokens)

Some examples of types of pull requests that are immediately helpful:

  - Fixing a bug without changing a public API.
  - Fixing or improving documentation.
  - Improvements to Maven configuration.

Guidelines for any code contributions:

1.  Any significant changes should be accompanied by tests. The project already
    has good test coverage, so look at some existing tests if you're unsure how
    to go about it.

### Resource Cleanup Pattern

Always use try-with-resources for `ResponseData` - temp files are auto-deleted on close.
