I'm building my own WebhookClient for dialog flow. My code is the following (using Azure Functions, similar to Firebase Functions): module.exports = async function(context, req) { const agent = new WebhookClient({ request: context.req, response: context.res }); function welcome(agent) { agent.add(`Welcome to my agent!!`); } let intentMap = new Map(); intentMap.set("Look up person", welcome); agent.handleRequest(intentMap); } I tested the query and the response payload looks like this: { "fulfillmentText": "Welcome to my agent!!", "outputContexts": [] } And the headers in the response look like
