Instructions

Simple Use

Sign in to OVHcloud APIs

On the OVHcloud API page, click Explore the OVHcloud API to view the list of APIs.

To use the APIs on your products, you must sign in to this site using your OVHcloud credentials.

• Click Authentication in the upper left.
• Select Login with OVHcloud SSO.

• Enter your OVHcloud credentials and click Login.

  If you are a sub-user, enter your account ID (in the format XXXX-XXXX-XX/user) and password.

• Click Authorize.

  If your OVHcloud account is protected by two-factor authentication, you will also need to enter the code generated by SMS or OTP mobile application or U2F key.

Explore available APIs

You can see a list of OVHcloud products that can be managed with APIs in the upper-left corner. This list is sorted alphabetically.

For example, to view the Public Cloud APIs, click /cloud in the list.

After you click the product, a list of the product’s APIs appears below.

There is also a Filter feature to limit the visible API calls. You can also use the selector to the left of the branch name to switch between the /v1 and /v2 branches of the API.

Run API

There are four types of APIs available that use what are called HTTP methods:

GET

The GET method is used to retrieve data from a resource.

For example, to retrieve a list of your instances, use the following API:

POST

The POST method is used to send additional data to the resource.

For example, to create a new instance, use the following API:

PUT

The PUT method is used to replace the current data in the resource with the data in the query.

For example, to alter an instance in your project, use the following API:

DELETE

The DELETE method is used to delete the called resource.

For example, to delete an instance from your project, use the following API:

API parameters

After you click the API you want, the REQUEST section allows you to assign variables for its application.

For example, when retrieving a list of instances in a project, you must enter the serviceName and can also add information in the region variable.

Once you have set the parameters, you can launch the API by clicking TRY.

The RESPONSE tab below provides the API execution report.

Scrolling down further will reveal PHP and Python tabs containing the elements to be added to your script, depending on the language used.

Advanced usage: pair OVHcloud APIs with an application

Create your app keys

Any application that wants to communicate with the OVHcloud API must be declared in advance.

The next screen will show you a set of three keys:

• the application key, or AK. For example:

7kbG7Bk7S9Nt7ZSV

• the application secret, or AS, is not to be disclosed. For example:

EXEgWIz07P0HYwtQDs7cNIqCiQaWSuHF

• the consumer key, or CK, is not to be disclosed. For example:

MtSwSrPpNjqfVSmJhLbPyr2i45lSwPU1

In this case, the CK key is attached to your account.

The CK token can be used for rights delegation.

First API usage

Once you have obtained your three keys (AK, AS, CK), you can sign API requests. The signature is calculated as follows:

"$1$" + SHA1_HEX(AS+"+"+CK+"+"+METHOD+"+"+QUERY+"+"+BODY+"+"+TSTAMP)

To simplify the development of your applications, OVHcloud provides API wrappers in multiple languages. Using them will help you avoid worrying about signing requests so that you can focus on developing your application.

• Python: https://github.com/ovh/python-ovh
• PHP: https://github.com/ovh/php-ovh
• Node.js: https://github.com/ovh/node-ovh
• Swift: https://github.com/ovh/swift-ovh
• C#: https://github.com/ovh/csharp-ovh

Here is an example of how to use the /me section to manage your OVHcloud account:

import ovh

# Instantiate. Visit https://api.us.ovhcloud.com/createToken/?GET=/me
# to get your credentials
client = ovh.Client(
    endpoint='ovh-eu',
    application_key='<application key>',
    application_secret='<application secret>',
    consumer_key='<consumer key>',
)

# Print nice welcome message
print("Welcome", client.get('/me')['firstname'])
