put https://api-demo.single-invoice.co/v2/coverage//settle
Settles a coverage policy, returning the details of the coverage upon success.
This method allows settling of a cover, and should be used once your invoice has been paid in full.
The quote must be in 'Activated', 'Claimed' or 'Timebarred' status to be approved.
Once a cover has been settled, it is no longer insured.
You can pass an optional 'settledat' parameter as the JSON body to this endpoint, specifying the date (in ISO 8601 timestamp format) that the invoice was settled. If this parameter is not present, it will use the time that the request was received as the settlement date.
