Create an IoTDA Instance

Function

This API is used to create an IoTDA instance. For details about the supported instance specifications, see Specifications.

[Constraints:

Ensure that your account balance is sufficient. This API cannot pay with coupons. When you create a yearly/monthly instance, if your account balance is insufficient, a pending order will be created.
To use a coupon, set is_auto_pay in the request to false and pay for the order by referring to Paying Yearly/Monthly Product Orders, or pay for the order on the Huawei Cloud official website.
For details about how to unsubscribe from yearly/monthly resources, see .

Debugging

You can debug this API through automatic authentication in API Explorer or use the SDK sample code generated by API Explorer.
