Connect a user's Google Cloud account once, then configure and run Pub/Sub - Publish Message from your backend or agent.

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({

externalUserId: "{external_user_id}", // any stable ID for this user in your system
configuredProps: {
google_cloud: { authProvisionId: "apn_xxxxxxx" },
