Quick Start

This section describes how to create a GeminiDB Cassandra instance by calling APIs.

Note

The token obtained from IAM is valid for only 24 hours. If you want to use a token for authentication, you can cache it to avoid frequently obtaining the token.

Involved APIs

If you use a token for authentication, you must obtain the user's token and add X-Auth-Token to the request message header of the service API when making an API call.

• API for obtaining tokens from IAM

• API for creating a GeminiDB Cassandra instance

Procedure

1. Use a token for authentication by referring to Authentication.

2. Send POST https://{Endpoint}/v3/{project_id}/instances.

3. Add X-Auth-Token to the request header.

4. Transfer the following parameters in the request body:

   Note

   Values of region and availability_zone are only for reference.

   For details about the API for creating instances, see Creating an Instance.
