Purchasing a FlexusL Instance

Function

This API is used to subscribe to one or more FlexusL instances.

This API is an asynchronous API. After a subscription API request is delivered, order_id and instances_ids are returned. In this case, the order is created, but the FlexusL instance is not created.

Use the order_id returned by this API to call the API of Querying Order Details. Check the creation status of the FlexusL instance based on the value of status in the response message. If the value of status is 5, the FlexusL instance is created.
