I have a list I want to update by calling the list API. I am able to get the data of this list by calling the Rest API, however I am not able to update a column data with PUT method. The API keeps giving me this message: 403 Forbidden. Please help. I will really appreciate it. Thanks

This could be permission related or it due to the digest number in the API call. Note the double underscore mentioned in the last response to this post.
