# Update a cXML Script

POST https://YOUR_SPACE.signalwire.com/api/laml/2010-04-01/Accounts/{AccountSid}/LamlBins/{Sid}
Content-Type: application/x-www-form-urlencoded

Changes the name or stored cXML document of a LamlBin by SID. The change is also visible through [Update cXML Script](/docs/apis/rest/cxml-scripts/update-cxml-script), because both operations manage the same script; server-backed [cXML Webhooks](/docs/apis/rest/cxml-webhook/update-cxml-webhook) are separate resources.

#### Permissions

The API token used to authenticate must have the following scope(s) enabled to make a successful request: _Voice_ or _Messaging_ or _Fax_.

[Learn more about API scopes](/docs/platform/your-signalwire-api-space).
