Learn to set up an API communication channel for your application in your NLX workspace

Create API channel

• Navigate to Channels tab of your application

• Expand API option

• Select + Create channel

Optional:

• API key: Matched against the HTTP headers from the conversational AI application

• Whitelisted domains: Domains authorized to make CORS calls to the API channel (you may need to add variations of your domain with a trailing slash / and without)

• MCP interface: Exposes a Model Context Protocol (MCP) interface for your API channel for all flows attached to the application that also have MCP enabled

  • Once turned on, provide an AI description in the application's settings tab for the MCP Client to reference. Check out our complete MCP guide for more information

• Voice: Enables users to interact with your application using voice over your web-based channel. See Developer docs for supporting with NLX Touchpoint. See list of languages supported

• Click Create channel

Touchpoint SDK configurator

We recommend using our official Touchpoint SDK to set up communication with API channels from within a web frontend. This contains:

• A vanilla JavaScript function for connecting to your application, maintaining a conversation, and subscribing to new messages

• Our React hook to operate inside a React app without providing styling

• A fully-styled, chat widget that is customizable to fit your style guide

To access the configurator:

• Create an application build and deploy
• Select the Details link next to the build's Deployed status

• Expand the API section of the modal

• Click Open Touchpoint configurator

To use the chat widget configurator, be sure to add https://developers.nlx.ai to the Whitelisted domains section of your API channel setup.
