This is AWS WAF Classic documentation. For more information, see
AWS WAF Classic
in the developer guide.
For the latest version of AWS WAF, use the AWS WAFV2 API and see the
AWS WAF Developer Guide.
With the latest version, AWS WAF has a single set of endpoints for
regional and global use.
When you want to create, update, or delete AWS WAF objects, get a change
token and include the change token in the create, update, or delete
request. Change tokens ensure that your application doesn't submit
conflicting requests to AWS WAF.
Each create, update, or delete request must use a unique change token.
If your application submits a
get_change_token
request and then
submits a second get_change_token
request before submitting a create, update, or delete request, the
second get_change_token
request
returns the same value as the first
get_change_token
request.
When you use a change token in a create, update, or delete request, the
status of the change token changes to PENDING
, which indicates that
AWS WAF is propagating the change to all AWS WAF servers. Use
get_change_token_status
to
determine the status of your change token.
