IBM Watson NLU

IBM Watson's Natural Language Understanding service.


The IBM's Natural Language Understanding service Analyzes text to extract metadata from content such as concepts, entities, keywords, categories, sentiment, emotion, relations, and semantic roles using natural language understanding.

API INFO: The Base URL used for the IBM Watson NLU connector is https://api.[location] More information can be found on their main API documentation (v1.0) site.


Within the workflow builder, highlight the IBM Watson NLU connector.

In the IBM Watson NLU connector properties panel to the right of the builder, click on the Authenticate tab and the 'Add new authentication' button.

This will result in a authentication pop-up modal. The first page will ask you to name your authentication and select the type of authentication you wish to create ('Personal' or 'Organisational').

The next page asks you for your 'API Key' and 'Service url'.

In order to get these fields, head to the IBM Cloud dashboard. Click the Navigation menu and then select the 'Resource List' option.

From the 'Resource list' page, make sure you have your required resource under the 'Services' tab. Select the appropriate resource. In our case, we need credentials for NLU, i.e., Natural Language Understanding.

If you do not have the appropriate resources added, you can always add the resource using the 'Create resource' button from the IBM Cloud dashboard.

Once you have selected the 'Natural Language Understanding' resource, you will be redirected to its page. From here, you can always use the auto-generated service credentials.

If you wish to create new credentials, select the 'Service credentials' tab from the left panel. Then click the 'New credential' button.

Give a suitable name to your credentials and click the 'Add' button.

A new set of credentials is auto-generated.

Once you have added these fields to your authentication pop-up window, click the 'Create authentication' button.

Go back to your settings authentication field (within the workflow builder properties panel), and select the recently added authentication from the drop-down options now available.

Your connector authentication setup should now be complete.
