One description. One production connector.
Four stages, each visible to you, each approved by you before the next begins.
01
Describe
Name the systems and the flow. Attach the policy or the rules document. NAP reads the business rules for you.

02
Build
NAP generates the connector from each system's own structure, on OAuth 2.0 and least-privilege roles. You approve the field map.

03
Prove
The connector runs against live transactions before go-live and passes a $0.00 variance gate. Evidence is kept, write-once.

04
Run
NAP generates the connector from each system's own structure, on OAuth 2.0 and least-privilege roles. You approve the field map.
Nothing goes live without your approval. Every action is written to a hash-chained audit record.
