Creates tags and add the tags to one or more Express Connect circuits.

Usage notes

Tags are used to classify instances. Each tag consists of a key-value pair. To use tags, make sure that the following requirements are met:

  • The keys of tags that are added to the same instance must be unique.
  • You cannot create tags without adding them to instances. All tags must be added to instances.
  • Tag information is not shared across regions.

    For example, you cannot view the tags that are created in the China (Hangzhou) region from the China (Shanghai) region.

  • You can add up to 20 tags to each instance. Before you add a tag to an instance, the system automatically checks the number of existing tags. If the maximum number of tags is reached, an error message is returned.

Debugging

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.
