Simple Log Service:PutWebtracking

Last Updated:Oct 26, 2023

Sends multiple logs to Log Service in one request.

Usage notes

  • An AccessKey pair is created and obtained. For more information, see AccessKey pair.

    The AccessKey pair of an Alibaba Cloud account has permissions on all API operations. Using these credentials to perform operations in Log Service is a high-risk operation. We recommend that you use a RAM user to call API operations or perform routine O&M. To create a RAM user, log on to the RAM console. Make sure that the RAM user has the management permissions on Log Service resources. For more information, see Create a RAM user and authorize the RAM user to access Log Service.

  • The information that is required to query logs is obtained. The information includes the name of the project to which the logs belong, the region of the project, and the name of the Logstore to which the logs belong. For more information, see Manage a project and Manage a Logstore.
  • You can call this operation to collect logs from web pages or clients.
  • If you use web tracking to collect logs and you do not call this operation, you can send only one log to Log Service in a request. For more information, see Use web tracking to collect logs.
  • If you want to collect a large amount of log data, you can call this operation to send multiple logs to Log Service in one request.
  • Before you can call this operation to send logs to a Logstore, you must enable web tracking for the Logstore. For more information, see Use web tracking to collect logs.
  • You cannot call this operation to send the logs of multiple topics to Log Service at a time.
  • If you call this operation, anonymous users from the Internet are granted the write permissions on the Logstore. This may generate dirty data because AccessKey pair-based authentication is not performed.


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.
