const pd = new PipedreamClient({
projectId: process.env.PIPEDREAM_PROJECT_ID!,
clientId: process.env.PIPEDREAM_CLIENT_ID!,
clientSecret: process.env.PIPEDREAM_CLIENT_SECRET!,
projectEnvironment: "production",
})
const result = await pd.actions.run({
id: "vapi-create-call",
externalUserId: "{external_user_id}", // any stable ID for this user in your system
configuredProps: {
vapi: { authProvisionId: "apn_xxxxxxx" },
name: "Conversation Name",
assistantId: "Assistant ID",
},
})
console.log(result)curl -X POST https://api.pipedream.com/v1/connect/{project_id}/actions/run \
