Mavenlink Timesheet Submissions API

Timesheet Submissions hold a set of time entries for a specified week, and can be approved, rejected, or canceled. You can enable timesheet submissions and approval in your [project settings](https://knowledge.kantata.com/hc/en-us/articles/204346530#Financials). Once enabled, time entries must be approved through a Timesheet Submission before it is invoiceable. **Note**: Each Timesheet Submission can only be associated with a single project. So when a timesheet is submitted through the UI with time entries for multiple projects, a separate Timesheet Submission object is created for each project in the backend. This section contains endpoints to approve, reject, or cancel a single timesheet submission. To approve, reject, or cancel multiple timesheet submissions at once, see [Timesheet Approvals](/tag/Timesheet-Approvals), [Timesheet Cancellations](/tag/Timesheet-Cancellations), and [Timesheet Rejections](/tag/Timesheet-Rejections).
