What custom integration development actually requires in 2026
2026 stack: MuleSoft Anypoint (enterprise), Workato (mid-market with strong AI), Boomi, Tray.io. For developer-led: custom Node/Python with OpenAPI specs, Composio for AI-driven integrations, Apache Camel for self-hosted ESB. EDI: AS2 + X12 via Cleo or 1EDI Source. Integration engineers must reason about idempotency, exactly-once vs at-least-once delivery, schema evolution (additive vs breaking), and compensation transactions. SaaS-to-SaaS-only generalists fail when the work touches EDI or banking ISO 20022.
