Canonical Model
The single vocabulary of business nouns and verbs that every connected system is translated into, and back out of.
A canonical model is the agreement about what a customer, an order, or an invoice is. Each system keeps its own field names. The model is what those fields mean, so a cust_ref in one system and an account.external_id in another are the same customer.
Ngentix translates every system into this vocabulary and back out again. Pairs are not pre-built. Shopify to NetSuite and Shopify to HubSpot are the same work, because both are translations into the model, not a map someone wrote for that pair.
This is the layer an iPaaS leaves to the customer’s integration team. It is also what an agent needs: a noun it can act on, rather than a payload whose fields disagree across systems.
