Instantly API v1-to-v2 Cutover

Overview

Move a production integration from deprecated API v1 to incompatible API v2 without silent behavior drift. Record assumptions, evidence, approval state, and rollback ownership so another operator can reproduce the result.

Prerequisites

• The target repository, Instantly workspace, environment, and accountable owner
• Current security, privacy, compliance, capacity, and change-control requirements
• An approved API v2 key only when a bounded live verification is necessary

Tool Discipline

Use Read, Glob, and Grep to inspect code, configuration, and evidence. Use WebFetch only for current first-party Instantly documentation and package metadata. Use Write or Edit only when implementation was requested and exact target files are known; never write credentials, lead data, email content, or unrestricted environment output.
