# Tree API

The TreeApi handles the retrieving or storing metadata to a certain path.

[[_TOC_]] 

Check out the [docs](https://coscine.rwth-aachen.de/coscine/api/Coscine.Api.Tree/swagger).

## 📝 Overview

The Tree API is a REST API that handles the retrieval or storage of metadata associated with a certain resource entry path in Coscine. With this API, you can easily manage metadata associated with your resources in the Coscine environment.

## ⚙️ Configuration

Before you can run and use the API, you need to ensure that the following dependencies and prerequisites are in place:

1. A Coscine database instance must be running. If you haven't set up a Coscine database instance yet, please refer to the [Coscine documentation]() for instructions on how to do so.

2. The Consul service should be correctly set up as a Key-Value store. If you haven't set up Consul yet, please refer to the [Consul documentation]() for instructions on how to do so.

3. The project's referenced .NET SDK(s) must be installed. Please refer to the project's source code for information on which .NET SDK(s) are required.

Once you have all the necessary dependencies and prerequisites in place, you should be able to run and use the API with the appropriate authentication credentials.

## 📚 API Reference

To get started with this project, you will need to ensure you have configured it correctly. Please refer to the configuration guide above. Once the project is running, you can access the API through the following Swagger endpoint:

```xml

<root>/coscine/api/Coscine.Api.Tree/swagger/index.html

```

To authenticate in Swagger with a Bearer JWT token, you will need to generate a token in Coscine under your _User Profile_. Once you have your token, you can open the Swagger documentation for the API you want to authenticate with and click on the "Authorize" button. In the "Authorization Value" field, you should enter `Bearer` followed by a space and then your Bearer JWT token. Click on the "Authorize" button to authenticate, and you should now be able to make authenticated requests to the API. 

> :bulb: Make sure to keep your Bearer JWT token secure, as it grants access to your account and API resources. If you suspect that your token has been compromised, you should generate a new one and invalidate all existing ones immediately.

For detailed information about each endpoint and the parameters they accept, please refer to the [API Swagger documentation](https://coscine.rwth-aachen.de/coscine/api/Coscine.Api.Tree/swagger/index.html).
