    1. API Description

    Domain name for API request: postgres.tencentcloudapi.com.

    This API is used to create one or more PostgreSQL instances. Instances created through this interface do not need to be initialized and can be used directly.

  • After an instance is successfully created, it will automatically start up, and its status changes to "Running".
  • For prepaid instances, the required amount for the instance purchase will be deducted in advance. For post-paid hourly instances, the amount required for the purchase within the first hour will be temporarily frozen. Please ensure that your account balance is sufficient before calling this interface.

    • A maximum of 100 requests can be initiated per second for this API.

    We recommend you to use API Explorer
    Try it
    API Explorer provides a range of capabilities, including online call, signature authentication, SDK code generation, and API quick search. It enables you to view the request, response, and auto-generated examples.
