Overview
Custom integrations are purpose-built connections—APIs, webhooks, queues, and small services in Node.js or Python—when off-the-shelf iPaaS hits a wall. PMD designs and builds these for reliability, observability, and ownership. Choose this when uniqueness, volume, or compliance demands it.
