Instantly Integration Reference Architecture

Overview

Produce a repo-grounded architecture that separates control-plane approvals from outreach mutations. 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.

Current Contract

• Use official API v2, the beta TypeScript SDK when appropriate, or the official CLI/MCP deliberately.
• Model workspace-wide throttling, cursor pagination, background jobs, and webhook delivery as first-class components.
• Keep campaign activation, account connection, key changes, and data deletion behind separate approvals.

Authentication

Use an API v2 key as Authorization: Bearer <key> against https://api.instantly.ai/api/v2. Grant only the endpoint-specific scopes needed, inject the key from an approved server-side secret manager, and never print, persist, commit, or place it in a URL. Treat key creation, rotation, revocation, member changes, workspace delegation, and production access as owner-approved actions.

Instructions

1. Map callers, workspaces, data stores, queues, secret managers, webhook receivers, and owners.
2. Define a typed client boundary with scoped authentication, redaction, timeouts, and rate control.
3. Separate read models, command handlers, background-job polling, and webhook idempotency.
4. Define tenant/workspace identity checks and x-as-workspace safeguards.
5. Trace lead and email data through retention, suppression, audit, and deletion controls.
6. Deliver topology, failure paths, capacity assumptions, approval boundaries, and rollback.

Approval Boundaries

Do not create, rotate, reveal, or revoke keys; invite or remove members; delegate across workspaces; connect sending accounts; create or activate campaigns; import or delete leads; change suppression or retention; register, patch, resume, or delete webhooks; alter plans or paid capacity; transmit diagnostics; or perform another production mutation without explicit approval from the accountable owner. Keep diagnosis read-only unless implementation was requested.

Output

Return the workspace-safe scope, files and contracts inspected, exact API v2 routes and required scopes, evidence collected, validation result, sensitive fields redacted, remaining risk, accountable owner, approval state, and rollback or next action.

Error Handling

Examples

Use a compact handoff that makes scope, mutation authority, and evidence reviewable.

Input:

system=outreach-orchestrator; workspaces=3; mutations=approval-gated

Expected handoff:

artifacts=context-map,sequence,failure-table,rollback
