$contentConfig = [
    'text' => $text,          // The only required value
    'id' => $string,          // Is the md5 of the text if not set

];

$contentItem = new ContentItem($contentConfig);
$contentItem->getContentItemJson();

$instance->addNewContentItem($contentItem);

Notes

Privacy

IBM have a mode that keeps a copy of your data on their side for the apparent training of Watson. This is normally opt-out.

As this isn't explicitly made clear, we have decided to disable by default so if you do with to help Watson learn then you can do so by opting-in as outlined in the examples above.

By default this package will not allow any tracking of any kind.

"Version"

This is the source of some confusion. This is a date in the format of 'YYYY-MM-DD' and Watson will use whichever version was around at that time.

Full quote

The requested version of the response format as a date in the form YYYY-MM-DD; for example, specify 2016-10-20 for October 20, 2016. The date that you specify does not need to match a version of the service exactly; the service replies with the response format whose version is no later than the date you provide. If you specify a date that is earlier than the initial release of version 3, the service returns the response format for that first version. If you specify a date that is in the future or otherwise later than the most recent version, the service returns the response format for the latest version.

Credentials

You can download your credentials in a json file, or get them from the developer console.

Unit tests

Test coverage is 100%, but you can also include a live API test to see if everything is working on that end. You shouldn't have to though, but it can be useful.

To do live test export

export DO_LIVE_API_TESTS=true

You must also include your real credentials.json in the root of the project (it is already in the gitignore).

Which will then do the live test.

Not yet supported

• Delete from ContentItems collection
• Modify within ContentItems collection
• Full error and exception handling
• Manipulation of the results
• Minimum text length configuration
• CSV
