Getting Started

Use the IONOS Cloud APIs to automate and integrate IONOS Cloud services.

Pick the API base URL

Most APIs use https://api.ionos.com/.

Some services use a service-specific host.

Generate an access token

Use Basic (username + password) or a secure token.

Both methods call GET /auth/v1/tokens/generate.

Make your first request

Use the returned access token in your API calls.

curl --request GET 'https://api.ionos.com/cloudapi/v6/datacenters' \
  --header 'Authorization: Bearer <access_token>'

Base URL

Use the base URL documented for the API you call.

Common base URL: https://api.ionos.com/

Authorization

Generate an access token, then use it in Authorization: Bearer <access_token>.

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 reseller accounts, Bearer Token Authentication improves handling because the additional header token for sub-contracts is not required.

Use your username and password to mint an access token.

Create a Base64 value of username:password.
```
printf '%s' 'username:password' | base64
```

Request an access token:

curl --location \
  --request GET 'https://api.ionos.com/auth/v1/tokens/generate' \
  --header 'Authorization: Basic <base64(username:password)>' \
  --data ''

Use the returned access token in your API calls:

curl --request GET 'https://api.ionos.com/cloudapi/v6/datacenters' \
  --header 'Authorization: Bearer <access_token>'

Use a secure token to mint an access token.

Generate a secure token (one-time setup):
- Generate via DCD
- Generate via CLI

Request an access token using your secure token:

curl --location \
  --request GET 'https://api.ionos.com/auth/v1/tokens/generate' \
  --header 'Authorization: Bearer <secure_token>' \
  --data ''

Use the returned access token in your API calls:

curl --request GET 'https://api.ionos.com/cloudapi/v6/datacenters' \
  --header 'Authorization: Bearer <access_token>'

HTTP status codes

The IONOS APIs use the following standard HTTP response codes:

Status code

Message

Description

200

OK

It indicates that the server has successfully processed the request.

201

Created

It indicates that the request has been fulfilled, resulting in the creation of a new resource.

202

Accepted

It indicates that the request has been accepted for processing, but the processing has not been completed yet.

204

No Content

It indicates that the server successfully processed the request, but there is no content to return in the response payload.

400

Bad Request

It indicates that the server cannot process the client's request due to invalid syntax or parameters.

401

Unauthorized

It indicates that the request requires user authentication and the client needs to provide valid credentials for access.

403

Forbidden

It indicates that the server understood the request, but the client does not have permission to access the requested resource.

404

Not Found

It indicates that the requested resource could not be found on the server.

409

Conflict

It indicates that the request could not be completed due to a conflict with the current state of the resource.

422

Unprocessable Entity

It indicates that the server understands the request, but it cannot process it due to semantic errors.

429

Too Many Requests

It indicates that the client has exceeded the rate limit or quota for accessing the server, and the request has been rejected.

500

Internal Server Error

It indicates that the server encountered an unexpected condition that prevented it from fulfilling the request.

503

Service Unavailable

It indicates that the server is temporarily unable to handle the request due to overloading or maintenance.

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.

Note: RFC7230 states header names are case insensitive.

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

The following IONOS APIs use the header parameters:

API

Supported Header Parameter

Cloud

X-Contract-Number

S3 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

The following is the description of the header parameters used in IONOS APIs:

Header parameter

Type

Description

X-Contract-Number

string

It specifies the contract number associated with the account making the request in the IONOS API. It is only required for the reseller master contract users if they are using Basic Auth as an authentication method. All other users can skip this header.

Content-MD5

string

It contains a base64-encoded MD5 hash of the request body content, ensuring data integrity during transmission.

x-amz-acl

string

It sets access control permissions for the resource, defining who can access it.

x-amz-grant-full-control

string

It grants full control permissions over the resource to the specified users or groups.

x-amz-grant-read-acp

string

It grants permission to read the Access Control Policy (ACP) for the specified resource.

x-amz-grant-write

string

It grants write permissions to the specified users or groups for the resource.

x-amz-grant-write-acp

string

It grants permission to write to the Access Control Policy (ACP) for the specified resource.

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

GET requests usually do not include a request body.

For example, for a POST request to /cloudapi/v6/datacenters, the request body can look like this:

Example

{
  "properties": {
    "name": "Test resource",
    "description": "My Production Datacenter",
    "location": "us/las",
    "secAuthProtection": false
  }
}

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.

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.

Once the datacenter resource is created, you will get a response.
