# ByteMatchSet
<a name="API_waf_ByteMatchSet"></a>

**Note**  
 AWS WAF Classic support will end on September 30, 2025.   
This is ** AWS WAF Classic** documentation. For more information, see [AWS WAF Classic](https://docs.aws.amazon.com/waf/latest/developerguide/classic-waf-chapter.html) in the developer guide.  
 **For the latest version of AWS WAF **, use the AWS WAFV2 API and see the [AWS WAF Developer Guide](https://docs.aws.amazon.com/waf/latest/developerguide/waf-chapter.html). With the latest version, AWS WAF has a single set of endpoints for regional and global use. 

In a [GetByteMatchSet](API_waf_GetByteMatchSet.md) request, `ByteMatchSet` is a complex type that contains the `ByteMatchSetId` and `Name` of a `ByteMatchSet`, and the values that you specified when you updated the `ByteMatchSet`. 

A complex type that contains `ByteMatchTuple` objects, which specify the parts of web requests that you want AWS WAF to inspect and the values that you want AWS WAF to search for. If a `ByteMatchSet` contains more than one `ByteMatchTuple` object, a request needs to match the settings in only one `ByteMatchTuple` to be considered a match.

 ** ByteMatchSetId **   <a name="WAF-Type-waf_ByteMatchSet-ByteMatchSetId"></a>
The `ByteMatchSetId` for a `ByteMatchSet`. You use `ByteMatchSetId` to get information about a `ByteMatchSet` (see [GetByteMatchSet](API_waf_GetByteMatchSet.md)), update a `ByteMatchSet` (see [UpdateByteMatchSet](API_waf_UpdateByteMatchSet.md)), insert a `ByteMatchSet` into a `Rule` or delete one from a `Rule` (see [UpdateRule](API_waf_UpdateRule.md)), and delete a `ByteMatchSet` from AWS WAF (see [DeleteByteMatchSet](API_waf_DeleteByteMatchSet.md)).  
 `ByteMatchSetId` is returned by [CreateByteMatchSet](API_waf_CreateByteMatchSet.md) and by [ListByteMatchSets](API_waf_ListByteMatchSets.md).
