Why teams connect Attio and Easypost

Keep the customers and orders that Attio and Easypost share aligned in real time, so sales works from live purchase history and the store works from current account details.

Attio holds the customer relationship: the contacts, accounts, and deals a go-to-market team works. Easypost runs the buying side: who placed which order, what they bought, and where it ships. The two describe the same people and companies, and when they are connected only by exports, sales answers questions without recent orders in front of them while the store works from account details that changed weeks ago.

Stacksync links Deals, Workspaces, Custom objects, People in Attio to Batch, CarrierAccount, Webhook, Shipment in Easypost with bi-directional, real-time sync. New customers, order activity, and corrected contact details move in whichever direction you configure, field by field, with conflicts resolved by rules you set. A record created or changed on either side shows up on the other within seconds, with no CSV exports and no nightly job.

The shared entity is the customer, matched on email or an external ID, so both systems agree on who the buyer is and the order history sits next to the relationship instead of in a separate tab.

Common use cases

  • 01 Run a two-way dual-run when migrating to Attio from another CRM.
  • 02 Sync companies, people, and deals with Postgres so ops teams enrich and update CRM records with SQL.
  • 03 When an order is ready to ship in an OMS, ERP, or database, create an EasyPost Shipment, buy the lowest qualifying Rate, and write the label URL and tracking code back onto the order.
  • 04 Create a Tracker for every outbound shipment and stream tracker.updated webhook events into Postgres or a warehouse so support and ops see live delivery status beside order records.

Common sync patterns

Where Attio segments customers: status travels to the store record

Lifecycle stage, tier, or account owner set in Attio syncs onto the customer record in Easypost, so the buying side can act on how the relationship is classified.

Where both keep product records: catalog and CRM products aligned

Where Attio tracks products or line items and Easypost holds the catalog, shared items are matched on SKU so quotes, deals, and orders reference the same products.

One customer identity across sales and store

A person who exists as a contact in Attio and a buyer in Easypost is kept as a single, deduplicated record, so both teams work from the same customer instead of two partial copies.

What you can sync between Attio and Easypost

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.

Attio objects Easypost objects How this pairing syncs
Custom objects Workspace-defined objects that behave like standard ones in the API. Parcel Package dimensions and weight (or a predefined_package); created standalone or inline on a Shipment and reused across shipments and batches. Custom objects is specific to Attio and Parcel to Easypost — each maps to any object or custom field on the other side.
People Standard person object; synced with marketing tools and warehouse person tables. Rate Carrier service and price options EasyPost generates on a Shipment; read-only - you select a rate id and buy it, you do not create or edit rates directly. People is specific to Attio and Rate to Easypost — each maps to any object or custom field on the other side.
Companies Standard company object; matched to billing and product accounts in two-way syncs. Tracker Tracking for a shipment by tracking_code and carrier; create a Tracker to begin tracking, read status and tracking_details, and receive tracker.updated events via webhook as the parcel moves. Companies is specific to Attio and Tracker to Easypost — each maps to any object or custom field on the other side.
Users Synced with incremental and full sync per the Stacksync docs. Batch Bulk shipment processing; create a batch, add or remove shipments, buy all labels at once, and generate a consolidated label or ScanForm for the day's orders. Users is specific to Attio and Batch to Easypost — each maps to any object or custom field on the other side.
Deals Pipeline records; read out for revenue reporting and written to from automation. CarrierAccount Carrier credentials and settings that control which carriers and negotiated rates are available; create, update, and delete to manage enabled carriers across accounts. Deals is specific to Attio and CarrierAccount to Easypost — each maps to any object or custom field on the other side.
Workspaces Synced with incremental and full sync per the Stacksync docs. Webhook Event subscriptions delivering an Event via HTTP POST on object changes; full CRUD (create, retrieve, list, update, delete) and the mechanism for near-real-time change delivery to Stacksync. Workspaces is specific to Attio and Webhook to Easypost — each maps to any object or custom field on the other side.

How changes propagate between Attio and Easypost

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.

Attio Easypost Sub-second propagation

DetectionAttio notifies Stacksync of record changes through webhook events. Webhooks on record and list-entry events, with polling as a fallback.

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

Rate-limit considerations

  • Attio: Subject to the platform's published API rate limits.
  • Easypost: Fixed 5 requests/second on index (list) endpoints plus a dynamic load-based limiter protecting buy and rate operations; exceeding either returns HTTP 429 Too Many Requests.
