Update Bins API

You can Update your JSON bins using the Update Bins API, and you can enable the Version Control as well.

Note that you cannot update the Bin Permissions and Name. In-order to change the Bin Permissions, then check out Change Privacy API for more info.

Root

https://api.jsonbin.io/v3

Route

/b/<BIN_ID>

Request Type

PUT

Request Headers

Below are the list of Accepted Request Headers if you are trying to Update a JSON record.

Request Header	Value	Required
Content-Type	application/json	Yes
X-Master-Key	<API_KEY>	Yes
X-Bin-Versioning	<true / false>	No

Content-Type Required

Set the Content-Type header to application/json. This needs to be passed with every POST request you make on the Create Bins Route. Failing to pass this in the Header will result in an error.

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.

X-Bin-Versioning Optionaldefault: false

You can enable Version Control on your Bins by passing the X-Bin-Versioning flag which is set to true. By default, the Version Control on Bin Updates is disabled. You can only save up to 1000 versions of a Bin, post that, it will not create any versions further.

Important You cannot disable version control on Public Bins as it's by design, to prevent the loss of data if someone updates your Public Bin. Though the Owner of the Bin can disable the Version Control if X-Master-Key is passed in the Headers with X-Bin-Versioning set to false.
