To delete a check, use the following endpoint:
You do not need to provide a body.
For example, the following payload deletes check cc:601 on claim cc:400.
<no request body>
Note that the DELETE endpoint is at the check level, not the check set level. If you want to delete an entire check set, you must delete each check in the check set individually.
Also keep in mind that ClaimCenter has business constraints around when and how a check can be deleted. For example, checks cannot be deleted once they have been escalated.
