Instantly Local Contract Loop

Overview

Develop safely without relying on an undocumented vendor mock endpoint or sending real outreach. 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

• The documentation exposes interactive examples but does not establish a durable public mock API contract.
• Use local fakes and captured synthetic schemas for deterministic tests.
• Live probes require a staging workspace, read-only scopes, and bounded requests.

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. Inventory routes and generate or pin types from the official OpenAPI surface.
2. Create local fake responses for success, 401, 403, 429, pagination, and malformed data.
3. Use synthetic leads and messages; never copy production payloads into fixtures.
4. Run unit and contract tests without network access.
5. Optionally run one owner-approved read-only staging probe.
6. Update fixtures only after reviewed schema evidence and record the source date.

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

Condition	Response
401	Stop and verify that the bearer key exists, is current, and was not revoked.
403	Stop and compare the operation with its exact required scope; do not broaden to all:all by default.
429	Coordinate the workspace-wide budget, honor endpoint overrides, and bound retries.
Schema or tenant mismatch	Fail closed, preserve redacted evidence, and do not retry a mutation.

Examples

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

Input:

mode=offline; fixture=campaign-list; network=false

Expected handoff:

unit=pass; contract=pass; staging=skipped
