# ListMLTransforms
<a name="API_ListMLTransforms"></a>

 Retrieves a sortable, filterable list of existing AWS Glue machine learning transforms in this AWS account, or the resources with the specified tag. This operation takes the optional `Tags` field, which you can use as a filter of the responses so that tagged resources can be retrieved as a group. If you choose to use tag filtering, only resources with the tags are retrieved.

If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in JSON format by the service.

 ** [NextToken](#API_ListMLTransforms_ResponseSyntax) **   <a name="Glue-ListMLTransforms-response-NextToken"></a>
A continuation token, if the returned list does not contain the last metric available.  
Type: String

 ** [TransformIds](#API_ListMLTransforms_ResponseSyntax) **   <a name="Glue-ListMLTransforms-response-TransformIds"></a>
The identifiers of all the machine learning transforms in the account, or the machine learning transforms with the specified tags.  
Type: Array of strings  
Length Constraints: Minimum length of 1. Maximum length of 255.  
Pattern: `[\u0020-\uD7FF\uE000-\uFFFD\uD800\uDC00-\uDBFF\uDFFF\t]*`
