More on OVH API Signature

OVH API signature refers to the process of creating a cryptographic signature for OVH API queries. OVHcloud employs API signatures to ensure the legality and security of requests sent to their platform. It ensures that only authorized apps have access to their resources.

1. Credentials: We’ll need three important pieces of data. Consumer Key (CK), Application Secret (AS). And to obtain these, create an app in the OVHcloud account.

2. Signature Creation: When making an API request, we’ll need to create a sign string. This string is created by combining several elements: A specific prefix (“1”), The hashed combination of the AS, CK, HTTP method used (e.g., GET, POST, PUT), API query string, request body (if any), and a timestamp.

3. Hashing Function: The hash function used is SHA-1. This function uses the combined parts to generate a unique fingerprint-like string.

4. Include the Signature: The created signature string is then added to the API request header. Typically, it is added under a header named “X-Ovh-Consumer”.

5. Usage: After getting these three keys (AK, AS, CK), we can sign API requests. We calculate the sign as follows:

OVHcloud offers API wrappers in different languages to help us create apps more efficiently. Using them will allow us to avoid worrying about signing requests and focus on developing the app.
