1. API Description

Domain name for API request: clb.tencentcloudapi.com.

This API is used to unbind a SCF function with a CLB forwarding rule. For L7 listeners, you need to specify the forwarding rule by using LocationId or Domain+Url.
This is an async API. After it is returned successfully, you can call the DescribeTaskStatus API with the returned RequestID to check whether this task is successful.

Limits:

• Binding with SCF is only available in Guangzhou, Shenzhen Finance, Shanghai, Shanghai Finance, Beijing, Chengdu, Hong Kong (China), Singapore, Mumbai, Tokyo, and Silicon Valley.
• SCF functions can only be bound with CLB instances of bill-by-IP accounts but not with bill-by-CVM accounts. If you are using a bill-by-CVM account, we recommend upgrading it to a bill-by-IP account.
• SCF functions cannot be bound with classic CLB instances.
• SCF functions cannot be bound with classic network-based CLB instances.
• SCF functions in the same region can be bound with CLB instances. SCF functions can only be bound across VPCs but not regions.
• SCF functions can only be bound with IPv4 and IPv6 NAT64 CLB instances, but currently not with IPv6 CLB instances.
• SCF functions can only be bound with layer-7 HTTP and HTTPS listeners, but not with layer-7 QUIC listeners or layer-4 (TCP, UDP, and TCP SSL) listeners.
• Only SCF event-triggered functions can be bound with CLB instances.

A maximum of 20 requests can be initiated per second for this API.
