Why teams connect Asana and Lemlist
Stop re-entering the same information in Asana and Lemlist: Stacksync keeps the records they share consistent in real time, in both directions.
Two tools in the daily stack often hold overlapping information: the same people, the same companies, or the same pieces of work, described twice. The tools do different jobs, so consolidating is not the answer; the overlap just needs to stop drifting.
Stacksync syncs Projects, Sections, Custom fields, Stories in Asana with Activities, Unsubscribes, Webhooks, Team Members in Lemlist in real time. You choose which records overlap, map the fields that should match, and pick a direction or let changes flow both ways. From then on, an update made in either tool is reflected in the other within seconds, without exports or copy-paste.
Because the sync is field-level, each tool keeps its own extras; only the shared data is held in agreement.
Common use cases
- 01 Write closed deals or new orders from a CRM or ERP into Asana Tasks to launch delivery, onboarding, or fulfillment projects automatically.
- 02 Mirror Projects, Sections, and Portfolios into a warehouse for cross-team reporting on status, timelines, and workload without CSV exports.
- 03 Stop or pause sequences automatically when a reply converts to a deal in the CRM
- 04 Mirror campaign performance data into BI tools for outbound reporting across senders
Common sync patterns
Where one tool produces events: mirror them in the other
Payments, replies, messages, or tickets created in one tool can create or update matching records in the other, keeping context in one place.
Where Lemlist is where the team documents or plans: keep its data fed
Information that originates in Asana stays current in Lemlist instead of going stale after a one-time paste.
Handoffs between teams
When work started in one tool continues in the other, the shared fields travel with it automatically.
What you can sync between Asana and Lemlist
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.
| Asana objects | Lemlist objects | How this pairing syncs | |
|---|---|---|---|
| Portfolios Collections of Projects for program-level rollup; read for cross-project status and progress reporting (Business and Enterprise). | Unsubscribes Opt-out records propagate to other outreach tools and the CRM for compliance. | Portfolios is specific to Asana and Unsubscribes to Lemlist — each maps to any object or custom field on the other side. | |
| Tags Labels applied across Tasks; synced as a many-to-many attribute for filtering and categorization. | Webhooks Hook subscriptions define which activity events are pushed to external endpoints. | Tags is specific to Asana and Webhooks to Lemlist — each maps to any object or custom field on the other side. | |
| Teams / Workspaces Organizational containers that hold projects and members; used to scope which projects a given sync covers. | Team Members Sender and seat records map outreach activity to reps in other systems. | Teams / Workspaces is specific to Asana and Team Members to Lemlist — each maps to any object or custom field on the other side. | |
| Tasks The primary unit of work and main record; created, updated, completed, and deleted via REST and synced two-way. Subtasks are Tasks with a parent reference. | Campaigns Outreach campaigns are the container leads are pushed into from CRMs and list-building workflows. | Tasks is specific to Asana and Campaigns to Lemlist — each maps to any object or custom field on the other side. | |
| Projects Collections of Tasks with a layout (list, board, timeline, calendar); each project maps to a synced table scope and its custom fields define the mapping. | Leads Per-campaign prospect records sync in from enrichment sources and back out with status. | Projects is specific to Asana and Leads to Lemlist — each maps to any object or custom field on the other side. | |
| Sections Ordered groupings of Tasks within a project; synced as a grouping attribute or category field on the row. | Activities Engagement records such as opens, clicks, replies, and bounces sync to CRM timelines. | Sections is specific to Asana and Activities to Lemlist — each maps to any object or custom field on the other side. |
How changes propagate between Asana and Lemlist
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.
Asana Lemlist Sub-second propagation
DetectionAsana notifies Stacksync of record changes through webhook events. Resource-scoped webhooks (established with an X-Hook-Secret handshake) POST events on create, change, and delete.
DeliveryEach detected change is written to Lemlist through its API, with automatic retries and rate-limit backoff.
Lemlist Asana Sub-second propagation
DetectionLemlist notifies Stacksync of record changes through webhook events. Webhooks on outreach activity events, plus polling.
DeliveryEach detected change is written to Asana through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Asana: Per token: 1,500 requests/minute on paid plans, 150/minute on free; the Search API is capped at 60/minute; concurrency caps at 50 GET and 15 write requests. Exceeding a limit returns HTTP 429 with a Retry-After header, and a separate cost-based limiter applies to complex graph traversals.
- Lemlist: Subject to the platform's API rate limits.

FAQ
Asana and Lemlist integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Asana and Lemlist: authenticate both systems, choose the objects to sync (such as Asana's Portfolios and Tags), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
-
Common patterns for Asana and Lemlist: Where one tool produces events: mirror them in the other; Where Lemlist is where the team documents or plans: keep its data fed; Handoffs between teams. Payments, replies, messages, or tickets created in one tool can create or update matching records in the other, keeping context in one place.
-
Asana: REST API (app.asana.com/api/1.0, JSON responses), plus resource-scoped Webhooks and a sync-token Events API. Authentication: OAuth 2.0 for multi-user apps, Personal Access Tokens (PATs) for single-account use and testing, and organization-scoped Service Accounts (Enterprise) for admin-level access. Lemlist: REST API. Authentication: API key. Stacksync manages authentication, retries, and rate limits on both sides.
-
Asana: Rate limits are per token: 1,500 requests/minute on paid plans and 150 on free, with the Search API capped at 60/minute; hitting a limit returns HTTP 429 with a Retry-After header. Lemlist: Activity events such as replies, opens, bounces, and unsubscribes can be delivered via webhooks, enabling near real-time updates to CRM records without polling every campaign. Stacksync's field mapping accounts for these differences between Asana and Lemlist without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Asana and Lemlist records are not retained after a sync operation.
