By default, all IBM Watson™ services log requests and their results. Logging is done only to improve the services for future users. The logged data is not shared or made public.
If you are concerned with protecting the privacy of users' personal information or otherwise do not want your requests to be logged, you can opt out of logging.
To prevent logging for any HTTP REST call to a Watson service, set the header parameter
1 for the request. (Any value other than
0 disables request logging for that call.) You must include the header on each request that you do not want to be logged.
X-WDC-PL-OPT-OUT deprecated: The earlier name,
X-WDC-PL-OPT-OUT, is deprecated, although it continues to work for now. The header accepts a value of
1 to opt out of request logging; any other value enables logging.
