Specify HTTP/REST with JSON as the invocation protocol. Add API key and Basic Auth as outbound authentication modes. Add per-system call timeouts. Classify errors by HTTP status for store-and-forward decisions (5xx/transient → retry, 4xx → permanent error to script). Document ADO.NET connection pooling for database connections. Update Store-and-Forward to clarify transient-only buffering.
