You can call the SwitchDBInstanceNetType operation to switch an ApsaraDB RDS instance between its internal and public endpoints.

To save endpoint resources, you can call this operation to switch an instance between its internal and public endpoints. After the endpoint that is used to connect to the instance is changed, you must update the endpoint information in the code of your application and restart the application.

Before you call this operation, make sure that the following requirements are met:

  • The instance is connected by using its internal or public endpoint.
  • The instance is in the Running state.
  • The number of times that you have switched the instance between its internal and public endpoints within the last 24 hours does not reach 20.
  • The instance resides in the classic network.


OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.
