## Instance Methods

Returns the steps Resource.

Creates an Execution.

Gets an Execution.

Lists Histories for a given Project.

Retrieves the next page of results.

Updates an existing Execution with the supplied partial entity.

### Method Details

`create(projectId=None, historyId=None, body, requestId=None)`

    Creates an Execution.

    The returned Execution will have the id set.

    May return any of the following canonical error codes:

    - PERMISSION_DENIED - if the user is not authorized to write to project - INVALID_ARGUMENT - if the request is malformed - NOT_FOUND - if the containing History does not exist

    Args:
      projectId: string, A Project id.

    Required. (required)
      historyId: string, A History id.

      body: object, The request body. (required)
        The object takes the form of:
