Attributes

config[RW]

The Configuration object holding settings to be used in the API client.

default_headers[RW]

Defines the headers to be used in HTTP requests of all API calls by default.

Save response body into a file in (the defined) temporary folder, using the filename from the “Content-Disposition” header if provided, otherwise a random filename. The response body is written to the file in chunks in order to handle files which size is larger than maximum Ruby String or even larger than the maximum memory a Ruby process can use.
