Removes tags from the resources of various Alibaba Cloud services.

Usage notes

After you remove a tag, the tag is automatically deleted within 24 hours if it is not added to other resources.

This topic provides an example on how to call the API operation to remove the tag whose tag key is k1 from the virtual private cloud (VPC) vpc-bp19dd90tkt6tz7wu**** in the cn-hangzhou region.

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.
