The standard REST API doesn't support the PUT method.

Each resource in the Force.com REST API is identified by a named URI, and is accessed using standard HTTP methods (HEAD, GET, POST, PATCH, DELETE).

(Source: Understanding Force.com REST Resources)

Depending on what you are trying to achieve you can use POST or PATCH.

To create a new record then you can use POST. For example to create a new Account you can POST to /services/data/v36.0/sobjects/Account

To update an existing record you can use PATCH. For example to update an existing Account you can PATCH to /services/data/v36.0/sobjects/Account/YOUR_ACCOUNT_ID
