Observe WhatsApp

When to use

Use this skill for operational diagnostics: Logs search, message delivery investigation, webhook delivery debugging, error triage, workflow event correlation, and WhatsApp health checks.

Setup

Preferred path:

• Kapso CLI installed and authenticated (kapso login)
• Start with kapso status to confirm project access and available WhatsApp numbers

Fallback path: Env vars:

• KAPSO_API_BASE_URL (host only, no /platform/v1)
• KAPSO_API_KEY

How to

Search logs

Use Logs search first when the user gives an identifier, endpoint, message ID, workflow execution ID, webhook delivery ID, request ID, or a vague "what happened?" debugging prompt.

Preferred path:

1. Search the current project: kapso logs search --query "<id-or-text>" --period 24h --source all --limit 20 --output json
2. If the exact search is empty, retry with --period 7d before concluding there are no logs.
3. Add --problems-only for broad error scans; leave it off when reconstructing an exact timeline.
4. Add explicit filters only when they intentionally narrow the search:
   • Workflow execution: kapso logs search --query "<execution-id>" --source flow_event --filter flow_execution_id=<execution-id> --period 7d --output json
   • API endpoint/status: kapso logs search --source external_api_log --filter endpoint_contains=/messages --filter response_status=500 --period 24h --output json
   • WhatsApp message ID: kapso logs search --query "wamid..." --source whatsapp_webhook_event --filter whatsapp_message_id=wamid... --period 7d --output json
   • Webhook delivery: kapso logs search --source webhook_delivery --filter webhook_id=<webhook-id> --period 24h --output json

Fallback path:

1. Search via Platform API: node scripts/log-search.js --query "<id-or-text>" --period 24h --source all --limit 20
2. Use filters with repeated flags: node scripts/log-search.js --source flow_event --filter flow_execution_id=<execution-id> --period 7d
3. Discover source and filter options: node scripts/log-search.js --catalog true

Logs sources are external_api_log, whatsapp_webhook_event, flow_event, and webhook_delivery. The Platform API fallback returns indexed Logs payloads for the API-key project and requires Logs and Elasticsearch to be enabled.

Investigate message delivery

Preferred path:

1. Search the WAMID or customer phone first: kapso logs search --query "<wamid-or-phone>" --period 7d --source all --limit 20 --output json
2. Resolve the number: kapso whatsapp numbers resolve --phone-number "<display-number>" --output json
3. List recent messages: kapso whatsapp messages list --phone-number "<display-number>" --limit 50 --output json
4. Inspect a specific message: kapso whatsapp messages get <message-id> --phone-number-id <id> --output json
5. Inspect the conversation: kapso whatsapp conversations list --phone-number "<display-number>" --output json

Fallback path:

1. List messages: node scripts/messages.js --phone-number-id <id>
2. Inspect message: node scripts/message-details.js --message-id <id>
3. Find conversation: node scripts/lookup-conversation.js --phone-number <e164>

Triage errors

Preferred path:

1. Confirm project and number state: kapso status
2. Run number health: kapso whatsapp numbers health --phone-number "<display-number>" --output human
3. Search recent problem logs: kapso logs search --problems-only --period 24h --source all --limit 20 --output json
4. Inspect related templates when relevant: kapso whatsapp templates list --phone-number "<display-number>" --output json

Fallback path:

1. Logs search: node scripts/log-search.js --problems-only true --period 24h --limit 20
2. Message errors: node scripts/errors.js
3. API logs: node scripts/api-logs.js
4. Webhook deliveries: node scripts/webhook-deliveries.js

Run health checks

Preferred path:

1. Project overview: kapso status
2. Phone number health: kapso whatsapp numbers health --phone-number "<display-number>" --output human

Fallback path:

1. Project overview: node scripts/overview.js
2. Phone number health: node scripts/whatsapp-health.js --phone-number-id <id>

OpenAPI

Install deps (once):

npm i

Examples:

node scripts/openapi-explore.mjs --spec platform search "webhook deliveries"
node scripts/openapi-explore.mjs --spec platform op listWebhookDeliveries
node scripts/openapi-explore.mjs --spec platform schema WebhookDelivery

Notes

• For webhook setup (create/update/delete, signature verification, event types), use integrate-whatsapp.
• For Project Event definitions, event-triggered workflow setup, or emit_event graph changes, use automate-whatsapp.
• Prefer resolving a display phone number to the canonical phone_number_id before deep debugging.
• Prefer Logs search before older single-resource log endpoints when correlating across messages, workflows, API calls, and webhook deliveries.
• Keep the scripts as the fallback path when the CLI is unavailable or when you need API-log or webhook-delivery inspection.
