# ListSigningPlatforms
<a name="API_ListSigningPlatforms"></a>

Lists all signing platforms available in AWS Signer that match the request parameters. If additional jobs remain to be listed, Signer returns a `nextToken` value. Use this value in subsequent calls to `ListSigningJobs` to fetch the remaining values. You can continue calling `ListSigningJobs` with your `maxResults` parameter and with new values that Signer returns in the `nextToken` parameter until all of your signing jobs have been returned.
