Batch Deleting Messages
Last updated: 2024-01-03 10:20:36
API Description
This API is used to batch delete up to 16 consumed messages. The consumer needs to use the
ReceiptHandle obtained after the last consumption as a parameter to locate the messages to be deleted.This operation can be successfully performed only before
NextVisibleTime. After NextVisibleTime elapses, the message will return to the Active status, and ReceiptHandle will become invalid, making it impossible to delete the message. In this case, the message needs to be consumed again to get a new ReceiptHandle. When a message is consumed by multiple consumers concurrently, if the message is deleted by one of the consumers, other consumers can no longer get it.The public/private domain names for API requests can be copied from Queue Service > API Request Address in the TDMQ for CMQ console. A sample address is as follows:
Public network address:
https://cmq-gz.publicXXX.tencenttdmq.comPrivate network address:
http://gz.mqadapter.cmq.tencentyun.comNote:
The API call URL varies by region.
Whenever downstream traffic is generated from using the public domain name, traffic fees will be charged (even during the beta test period). Therefore, we strongly recommend you use the private domain name to avoid traffic fees.
