Implementation considerations
  • Protocol connectors are intentionally broad; start with simple get/create/update/delete or send/receive operations and add schema-specific behavior per customer.
  • Confirm authentication, TLS, VPN/private networking, payload schema, idempotency keys, rate limits, and retry expectations.
  • Keep secrets out of payloads, prompts, and logs; store credentials centrally and redact sensitive fields.
