PUT and PATCH

The CAVATICA API has two method to modify file metadata. This method uses the HTTP verb PUT, and the other uses the HTTP verb PATCH.

The difference between the two concerns the way that they update the information stored about the user. PATCH allows you to update just one metadata field. On the other hand, a PUT request will fully overwrite the values for all metadata fields. This means that when issuing a PUT request you must enter values for every key required to specify the metadata, even if the values for some keys are unchanged. If you don't specify a value for a given metadata field when making the PUT request, then any existing value for that field will be reset.

Request

Example request

Since you need to specify values for all metadata fields, it can be easier to send the data as a file, using the option --data-binary in cURL.
