Token IDs

How to Use the NLP API Product

Select the API SPECIFICATIONS tab. The NLP API product will be displayed.

Endpoints are listed in the left panel (click texts to expand the full list of endpoints). Click on an endpoint to view the description, available parameters, response codes, example requests and responses, and to generate a request.

Example Requests/Responses: Use the drop-down menu to view code examples in the selected programming language.

Generating an API Request

There are multiple ways to generate a request:

  • via the inline panel: Each endpoint page contains a panel on the right that provides sections for Authorization (Auth), Parameters (where applicable) and Body. Requests are generated by clicking the Send API Request button.
  • via a third-party API client: Any third-party API client that utilizes any of the supported programming languages can be used to send a request to any of the Cortical.io NLP API endpoint URLs.

*You must include the Token ID. Regardless of how you generate the request, whether you use the inline panel (Auth section) or send a request through a third-party API client, you must include the app-specific Token ID as part of the request.

How to locate the Token ID: Your Token ID can always be accessed by navigating back to Apps & Subscriptions via the username drop-down menu at the top of the Cortical.io Developer Portal (your_username / Apps & Subscriptions) and selecting the associated app from the My Apps page.
