Why teams connect Gmail and Ironclad

Sync the people, users, and work records in Ironclad with the calls, messages, and events in Gmail, in real time and in both directions.

Ironclad holds the records a team works from: the contacts, the tickets or tasks, the users, and the history attached to each. Gmail moves the actual communication, whether that is a call, a text, an email, or a meeting, and every one of those is tied to a person and often to a user on your side. When the two are connected only by manual entry or a nightly export, the communication happens in one system while the record it belongs to sits in another, so people rebuild context by hand and reach out from contact lists that are already out of date.

Stacksync syncs Workflows, Records, Entities, Obligations in Ironclad with Drafts, Attachments, History, Messages in Gmail bi-directionally and in real time. Contacts and users maintained in Ironclad feed Gmail so outbound dialing, messaging, and invites reach current numbers and addresses, and the calls, messages, and meeting events Gmail produces attach to the matching record in Ironclad within seconds. Everything is mapped field by field, with conflict resolution in place of copy-paste, and there is no middleware to build, no rate limits to babysit, and no batch job that leaves the morning running on yesterday's data.

Because the sync is field-level, each system keeps its own extras; only the shared people, users, and activity are held in agreement.

Common use cases

  • 01 Two-way sync Ironclad Records with a warehouse or ERP so executed-contract value, counterparty, renewal dates, and status stay current without manual re-keying.
  • 02 Sync Entities (counterparties) two-way with a CRM or ERP so company and vendor master data matches across the CLM and the systems of record.
  • 03 Read Attachments and message metadata into a warehouse or document store for retention, discovery, and compliance reporting.
  • 04 Mirror Labels with pipeline or ticket states so triage done in an external tool is reflected inside the inbox.

Common sync patterns

Where Gmail places calls or sends messages: activity on the record

Calls, texts, emails, or meeting events from Gmail attach to the matching contact, ticket, or item in Ironclad, so the full history lives with the record instead of in a separate log.

One user and agent roster

Users kept in Ironclad map to accounts, seats, or extensions in Gmail, so the same people exist on both sides and ownership stays meaningful across the two systems.

Turn a communication into follow-up work

A completed call, an inbound message, or a delivery result in Gmail can create or update a ticket, task, or record in Ironclad, so nothing that happens on a call or in a thread gets dropped.

What you can sync between Gmail and Ironclad

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Gmail objects Ironclad objects How this pairing syncs
Labels User and system labels (INBOX, SENT, custom); applied and removed via sync to mirror pipeline stages or triage states from an external system. Webhooks Event subscriptions that push workflow, approval, signature, document, and comment changes to Stacksync in near real time; created, listed, and deleted through the API across 40+ event types. Labels is specific to Gmail and Webhooks to Ironclad — each maps to any object or custom field on the other side.
Drafts Unsent messages; created and updated from templates or sequence tools so reps review before sending from their own mailbox. Workflow Approvals Per-workflow approval requests and their state; read to report approval status and cycle time, and status changes arrive live through the workflow_approval_status_changed event. Drafts is specific to Gmail and Workflow Approvals to Ironclad — each maps to any object or custom field on the other side.
Attachments File payloads referenced by message part; read out to storage or a document system for archival and compliance workflows. Signature Packets The e-signature packets on a workflow (sent, signatures collected, fully signed); read to track signing progress, with packet events delivered by webhook for real-time status. Attachments is specific to Gmail and Signature Packets to Ironclad — each maps to any object or custom field on the other side.
History The incremental change log keyed by historyId; used for efficient delta sync so only mailbox changes since the last cursor are fetched. Workflow Documents Draft and executed documents attached to a workflow; retrieved to pull generated or signed files out into a document store or archive. History is specific to Gmail and Workflow Documents to Ironclad — each maps to any object or custom field on the other side.
Messages Individual emails with headers, body, and label state; read out to a CRM or warehouse for activity logging, and sent or modified two-way from sales tools. Workflows The core unit of Ironclad: a live contract process (NDA, MSA, order form) moving through creation, review, approval, and signature. Launched via POST, updated via PATCH, and read for status, so contract processes move two-way between Ironclad and a database, CRM, or ERP. Messages is specific to Gmail and Workflows to Ironclad — each maps to any object or custom field on the other side.
Threads Conversation groupings that keep replies together; synced so a CRM timeline or support desk shows the full exchange, not isolated messages. Records The Repository of executed and stored contracts with metadata (value, counterparty, key dates, type) and attachments; full create, read, update, and delete so signed-contract data and PDFs sync to a warehouse, ERP, or CRM. Threads is specific to Gmail and Records to Ironclad — each maps to any object or custom field on the other side.

How changes propagate between Gmail and Ironclad

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Gmail Ironclad Sub-second propagation

DetectionGmail notifies Stacksync of record changes through webhook events. Incremental sync via users.history.list from a stored historyId cursor, plus real-time push notifications through Google Cloud Pub/Sub watch on the.

DeliveryEach detected change is written to Ironclad through its API, with automatic retries and rate-limit backoff.

Ironclad Gmail Sub-second propagation

DetectionIronclad notifies Stacksync of record changes through webhook events. Native webhook subscriptions (POST /webhooks) fire on 40+ workflow, approval, signature, document, and comment events, and Ironclad retries a failing.

DeliveryEach detected change is written to Gmail through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Gmail: Quota is measured in units per user per second (e.g. messages.list = 5 units, messages.send = 100 units) against a 250 quota-unit/user/second limit and a daily project cap; exceeding limits returns 429 with exponential backoff expected.
  • Ironclad: Limits are enforced per account per minute by endpoint: GET Workflows 400 and POST/PATCH Workflows 40; GET Records 600 and POST/PATCH Records 200; GET Entities 600 and POST/PATCH Entities 200; Webhooks 600; all other endpoints 800. Exceeding a limit returns HTTP 429, and Ironclad recommends exponential backoff with jitter.

How the Gmail and Ironclad connectors work

Gmail

Integration surface
Gmail API (REST, v1)
Authentication
OAuth 2.0 via Google — user-authorized consent with granular scopes (gmail.readonly, gmail.modify, gmail.send, gmail.labels); restricted scopes require Google's app verification for production use
Change detection
Incremental sync via users.history.list from a stored historyId cursor, plus real-time push notifications through Google Cloud Pub/Sub watch on the mailbox (watch must be renewed at least every 7 days)

Ironclad

Integration surface
REST/JSON Public API (CLM API) at https://na1.ironcladapp.com/public/api/v1 (NA1 and EU1 regions plus a demo/sandbox), with a native Webhooks subscription API; described by an OpenAPI 3.1 spec.
Authentication
OAuth 2.0 - Authorization Code grant (PKCE for public clients) and Client Credentials grant for server-to-server; access tokens are Bearer, expire after 6 hours, and every endpoint is gated by a resource scope. The legacy static API bearer token was deprecated on 2024-11-22.
Change detection
Native webhook subscriptions (POST /webhooks) fire on 40+ workflow, approval, signature, document, and comment events, and Ironclad retries a failing endpoint up to 10 times over about 13.6 hours with exponential backoff. Otherwise poll the list endpoints by last-updated. There is no database change-data-capture log.
