Mocean SMS & Voice Automation

This workflow automates secure SMS and voice message delivery via Mocean API, replacing fragmented manual scripting or unreliable third-party tools that expose teams to rate limits, invalid formats, and compliance risks—wasting 10-15 hours weekly on failed sends for 1,000+ notifications. It processes webhook requests with metadata extraction, enforces IP-based rate limiting (10/min), validates/sanitizes inputs (phone E.164, message length, prohibited spam patterns), estimates costs, routes by resource (SMS/voice), prepends priority tags, sends via Mocean nodes, and handles errors with detailed JSON responses. Key nodes: Authenticated Webhook Trigger (/mocean/communications), Set for metadata (requestId, IP, timestamp), Code for rate limiting/static data and validation (regex checks, language lists), IFs for limits/validation/cost (>0.1 USD warns)/resource/error types, Sets for message prep (e.g., '[URGENT] ' prefix), dual Mocean nodes (SMS: to/from/message; Voice: +language/resource), and RespondToWebhooks for 200/400/429/500/202 statuses with headers like X-RateLimit-Remaining. This equips support/marketing teams at SMBs (20-100 employees) dispatching alerts, verifications, or campaigns, ensuring 99% delivery uptime and audit-ready logs without dev overhead.\n\nDeployment slashes failed sends 80%, saving 8-12 hours/week on 500+ messages while cutting costs 20% via thresholds—ROI in 2 months for high-volume ops. Suited for fintech alerts or e-commerce confirmations. Requires Mocean API ($0.01/SMS, $0.05/min voice, free sandbox), n8n Cloud ($20/mo), webhook auth setup. Scales to 5k/day but throttle at Mocean's 100/sec; integrates Zapier for CRM triggers.\n\nDocker n8n (n8n.io/download: docker run -p 5678:5678 n8nio/n8n) or cloud.n8n.io (5-min). Mocean creds: moceanapi.com (API key/secret as n8n Mocean node). Header Auth: n8n credentials for webhook (name/value pairs). Import JSON, test Code nodes: Execute 'Validate and Sanitize Input' with sample {resource:'sms',to:'+1234567890',message:'Test'}. Set webhook path 'mocean/communications', production for URL https://your.n8n.cloud/webhook/mocean-communications-production-webhook. Adjust validation regex/languages in Code if needed.\n\nTest: POST curl -X POST -H 'Authorization: Bearer test' https://your.n8n.cloud/webhook/mocean/communications -d '{"resource":"sms","to":"+1234567890","message":"Hello"}'; check Mocean dashboard for send, responses for IDs/errors. Errors: 429 Rate (tune Code window), 400 Invalid Phone (E.164 format), 401 Auth (rekey Mocean). Activate toggle, monitor executions. Maintain: Rotate keys quarterly, audit static rate data, update prohibited patterns; optimize with Webhook retries for transients.
