Deletes an envelope lock

This method locks the specified envelope and sets the time until the lock expires to prevent other users or recipients from changing the envelope. The response to this request includes a `lockToken` parameter that you must use in the `X-DocuSign-Edit` header for every PUT method (typically a method that updates an envelope) while the envelope is locked. If you do not provide the `lockToken` when accessing a locked envelope, you will get the following error: ``` { "errorCode": "EDIT_LOCK_NOT_LOCK_OWNER", "message": "The user is not the owner of the lock. The template is locked by another user or in another application" } ``` ### The X-DocuSign-Edit header The `X-DocuSign-Edit` header looks like this and can be specified in either JSON or XML. **JSON** ``` { "LockToken": "token-from-response", "LockDurationInSeconds": "600" } ``` **XML** ``` <DocuSignEdit> <LockToken>token-from-response</LockToken> <LockDurationInSeconds>600</LockDurationInSeconds> </DocuSignEdit> ``` In the actual HTTP header, you would remove the linebreaks: ``` X-DocuSign-Edit: {"LockToken": "token-from-response", "LockDurationInSeconds": "600" } or X-DocuSign-Edit:<DocuSignEdit><LockToken>token-from-response</LockToken><LockDurationInSeconds>600</LockDurationInSeconds></DocuSignEdit> ``` ### Related topics - [Common API Tasks: Locking and unlocking envelopes](https://www.docusign.com/blog/dsdev-common-api-tasks-locking-and-unlocking-envelopes)
