# Get Started with IONOS Cloud API

Learn how to use the <code class="expression">space.vars.ionos\_cloud\_api</code> and begin integrating them to leverage the capabilities of IONOS Cloud services through this guide.

## Base URL

Provide the Base URL of the <code class="expression">space.vars.ionos\_cloud\_api</code>. **Example:** `https://api.ionos.com/`

## Authorization

To log in to the <code class="expression">space.vars.ionos\_cloud\_api</code>, you need to use either of the following authentication methods:

{% hint style="info" %}
**Note:**

* All user accounts with currently **2FA enabled** or **forced** need to use the **Bearer Token Authentication** method.
* The **Basic Authentication** method will be discontinued in the near future and it should be used in combination with **2FA** to increase security.
* For the **Reseller** accounts, the **Bearer Token Authentication** improves handling as the additional header token for sub-contracts is not be required.
  {% endhint %}

{% tabs %}
{% tab title="Basic Authentication" %}
To authenticate using a Basic Authentication with the <code class="expression">space.vars.ionos\_cloud\_api</code>, follow these steps:

1. Request a token using the following `GET` command:

   ```bash
       {{BaseURL}}/auth/v1/tokens/generate
   ```
2. You need to pass the **encoded Base64** token in your CURL command. You can obtain the [<mark style="color:blue;">Encoded Base64</mark>](https://www.base64encode.org/) format and generate the token by using:
   * Username
   * Password
3. Once you receive the Base64 encoded token, you can use it in your cURL command to obtain the Basic Authentication token:

   ```bash
   curl --location \
   --request GET 'https://api.ionos.com/auth/v1/tokens/generate' \
   --header 'Authorization: Basic WVhKemFHRmtMbUoxYzJoeVlVQnBiMjV2Y3k1amIyMDZJMUJoYTJsemRHRnVYekU9' \
   --data ''
   ```
4. If your request is successful, the response will include an access token. This token is a string of characters that serves as your authentication credential for subsequent API requests. Retrieve the access token to interact with the APIs.
   {% endtab %}

{% tab title="Bearer Token Authentication" %}
To authenticate using a Bearer Token with the <code class="expression">space.vars.ionos\_cloud\_api</code>, follow these steps:

1. Request a token using the following `GET` command:

```bash
    {{BaseURL}}/auth/v1/tokens/generate
```

2. You need to pass the **secure token** in your cURL command. You can obtain the secure token by using:

* [<mark style="color:blue;">Generate authentication token via DCD</mark>](https://docs.ionos.com/cloud/set-up-ionos-cloud/management/identity-access-management/token-manager#generate-authentication-token)
* [<mark style="color:blue;">Generate authentication token via API</mark>](#authorization)
* [<mark style="color:blue;">Generate authentication token via CLI</mark>](https://docs.ionos.com/cli-ionosctl/subcommands/authentication/token/generate)

3. Once you receive the secure token, you can use the access token in your cURL command to obtain the Bearer Token:

```bash
curl --location \
--request GET 'https://api.ionos.com/auth/v1/tokens/generate'
--header 'Authorization: Bearer eyJpZCI6MTUsInVzZXJuYW1lIjoia21pbmNoZWxsZSIsImVtYWlsIjoia21pbmNoZWxsZUBxcS5jb20iLCJmaXJzdE5hbWUiOiJKZWFubmUiLCJsYXN0TmFtZSI6IkhhbHZvcnNvbiIsImdlbmRlciI6ImZlbWFsZSIsImltYWdlIjoiaHR0cHM6Ly9yb2JvaGFzaC5vcmcvYXV0cXVpYXV0LnBuZz9zaXplPTUweDUwJnNldD1zZXQxIiwiaWF0IjoxNjM1NzczOTYyLCJleHAiOjE2MzU3Nzc1NjJ9.n9PQX8w8ocKo0dMCw3g8bKhjB8Wo7f7IONFBDqfxKhs' \
--data ''
```

4. If your request is successful, the response will include an access token. This token is a string of characters that serves as your authentication credential for subsequent API requests. Retrieve the access token to interact with the APIs.

## Request schema

It is the format of the data that is being sent in the request body when interacting with an API endpoint. Request schema has all expected properties, data types, and constraints or validations that should be applied to the request payload. The request schema is specified using `JSON Schema` or another schema definition language supported by OpenAPI.

### Path parameters

Path parameters allow dynamic routing, and you can request different resources using a common endpoint structure. This does not include the **host** or **base path** of the API. For example, in `/datacenter/{datacenterId}`, the path parameter is `datacenterId`.

| **Path parameter** | **Type** | **Required** | **Description**                          |
| ------------------ | -------- | ------------ | ---------------------------------------- |
| `datacenterId`     | string   | Yes          | The unique identifier of the datacenter. |
|                    |          |              |                                          |

### Query parameters

Parameters that are appended to the URL to customize the request and filter data. For example, in `/datacenters?depth=###`, the query parameter is `depth`.

| **Query parameter** | **Type** | **Required** | **Description**                                                                          |
| ------------------- | -------- | ------------ | ---------------------------------------------------------------------------------------- |
| `depth`             | int      | Optional     | The depth of query parameter used to specify how many levels of URIs should be expanded. |
|                     |          |              |                                                                                          |

### Header parameters

Custom headers are expected as part of the request and are sent in the header section. They are usually used for authentication tokens, content type negotiation, caching directives, and other metadata related to the request. HTTP Headers are an important part of the API request and response as they represent the meta-data associated with the API request and response.

{% hint style="info" %}
**Note:** [<mark style="color:blue;">RFC7230</mark>](https://datatracker.ietf.org/doc/html/rfc7230#page-22) states header names are case insensitive.
{% endhint %}

For IONOS Cloud Object Storage, the headers carry information that is compatible with the S3 standard and, therefore, may require specific headers for certain operations.

The following <code class="expression">space.vars.ionos\_cloud\_api</code>s use the header parameters:

| **API**        | **Supported Header Parameter**                                                                                               |
| -------------- | ---------------------------------------------------------------------------------------------------------------------------- |
| Cloud          | `X-Contract-Number`                                                                                                          |
| Object Storage | `Content-MD5`, `x-amz-acl`, `x-amz-grant-full-control`, `x-amz-grant-read-acp`, `x-amz-grant-write`, `x-amz-grant-write-acp` |

## Request body

The request body is described using a schema that defines the structure and format of the data expected in the body of the request. This schema can include parameters, `JSON`, `XML`, or other data formats specific to the API design. This data is then sent by the client to the server in an HTTP request.

### Request

For example, for `GET` request for `/cloudapi/v6/datacenters` API, we have the following request body sample:

<details>

<summary>Example</summary>

```
 {
   "properties":{
      "name":"Test resource",
      "description":"My Production Datacenter",
      "location":"us/las",
      "secAuthProtection":false
   },
   "entities":{
      "servers":{
         "_links":{
            
         }
      },
      "volumes":{
         "_links":{
            
         }
      },
      "loadbalancers":{
         "_links":{
            
         }
      },
      "lans":{
         "_links":{
            
         }
      }
   }
}
```

</details>

### Response

| **Status code** | **Response** | **Description**                                                                                                                                                                                                       |
| --------------- | ------------ | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `202`           | `Accepted`   | The request is received and accepted for processing. The creation process is still ongoing, and the server will need some time to complete the creation of the datacenter resource before returning a final response. |

{% hint style="info" %}
**Note:** This example is for the **CloudAPI** with a successful acceptance returned with **HTTP 202**; this could be different for other APIs. For CloudAPI, resources are created asynchronously and handled by other endpoints. You can check for the progress via the **Status URL** that is returned in the response header of the **POST** or **PUT** call.

**Example:** `GET https://api.ionos.com/cloudapi/v6/requests/abcxea-0001-9910-Y1Y2-aXXAAbnxxa/status` can be used to check the processing state of your request.
{% endhint %}
