Request Type


Request Headers

Below are the list of Accepted Request Headers if you are trying to Delete a JSON records versions.

Request Header Value Required
X-Master-Key <API_KEY> Yes
X-Preserve-Latest <true/false> No
X-Master-Key Required

X-Master-Key is nothing but your Core API Access Key. You will need this Key to access mostly any API end-point on JSONBin. You could find the key on the API Keys page.


Using X-Preserve-Latest header will copy the Latest record to the Base record before deleting all the versions of a bin, thus, retaining the last updated version.
