​
Summary

Successfully tested production webhook endpoint after merging PR #136 (nanoid dependency fix).

​
Test Execution

Date: October 4, 2025 Endpoint: POST https://activation-api-66ca3rk35a-uc.a.run.app/webhooks/creative-status/:customerId/:creativeId Build: Cloud Build 8db7a473 (commit 2101c12) - Deployed at 20:37 UTC

​
Results

​
✅ Issues Fixed

  1. Missing nanoid dependency - RESOLVED
    • Previously: Cannot find package 'nanoid' (500 error)
    • Now: Package installed and loaded successfully
  2. Endpoint routing - RESOLVED
    • Previously: 404 Not Found (wrong URL or not deployed)
    • Now: Endpoint responds correctly
  3. CI test failures - RESOLVED
    • Previously: nanoid ID length pattern mismatch
    • Now: All tests passing

​
⚠️ New Issue Found

PostgreSQL Connection Required 
{
  "error": "connect ECONNREFUSED 127.0.0.1:5432",
  "received": false
}
Root Cause: Operations framework was converted from BigQuery to PostgreSQL in PR #128 (commit 621fe38), but production environment doesn’t have PostgreSQL configured. Required Configuration:
  • Either DATABASE_URL environment variable (connection string)
  • Or individual variables: POSTGRES_HOST, POSTGRES_PORT, POSTGRES_USER, POSTGRES_PASSWORD, POSTGRES_DATABASE
Default Values (from src/utils/postgres-factory.ts): 
host: process.env.POSTGRES_HOST || "localhost";
port: parseInt(process.env.POSTGRES_PORT || "5432", 10);
user: process.env.POSTGRES_USER || "postgres";
password: process.env.POSTGRES_PASSWORD || "postgres";
database: process.env.POSTGRES_DATABASE || "activation_api";

​
Next Steps

  1. Create Cloud SQL PostgreSQL instance
  2. Configure Cloud Run service to connect via:
    • Unix socket (recommended): /cloudsql/PROJECT:REGION:INSTANCE
    • Or TCP with Cloud SQL Proxy
  3. Add environment variables to Cloud Run deployment: 
    gcloud run services update activation-api \
  --add-cloudsql-instances=PROJECT:REGION:INSTANCE \
  --set-env-vars="DATABASE_URL=postgresql://user:password@/activation_api?host=/cloudsql/PROJECT:REGION:INSTANCE"

​
Option 2: Use Neon/Supabase Serverless PostgreSQL

  1. Create Neon/Supabase project
  2. Get connection string
  3. Add to Cloud Run: 
    gcloud run services update activation-api \
  --set-env-vars="DATABASE_URL=postgresql://..."

​
Option 3: Revert to BigQuery (Temporary)

If PostgreSQL is not ready for production, consider temporarily reverting the operations framework to use BigQuery until PostgreSQL infrastructure is set up.

​
Conclusion

The webhook code is fully functional and deployed correctly. The only remaining blocker is infrastructure setup - production needs a PostgreSQL database configured for the operations framework to store webhook operations and actions. Once PostgreSQL is configured, webhooks will work end-to-end:
  1. Sales agent sends status update → Webhook endpoint
  2. Webhook receiver validates and stores in PostgreSQL operations table
  3. Customer webhook notifications can be triggered (if configured)
