Why teams connect Easypost and Nutshell

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

Nutshell 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 Leads, People, Companies, Activities in Nutshell to Rate, Tracker, Batch, CarrierAccount 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 Sync Nutshell leads into a warehouse or Postgres so small B2B teams can report on pipeline without exports.
  • 02 Push closed-won leads to accounting software to trigger invoicing automatically.
  • 03 Verify and normalize customer Addresses through EasyPost before they are saved to the CRM or OMS to cut failed deliveries and carrier address-correction surcharges.
  • 04 Sync CarrierAccount configuration and negotiated rates so shipping options stay consistent across the storefront, ERP, and 3PL systems.

Common sync patterns

Contact and address details stay consistent

An email, phone, or shipping and billing address corrected in either system updates the other, so the next order and the next outreach both use current information.

Where Nutshell segments customers: status travels to the store record

Lifecycle stage, tier, or account owner set in Nutshell 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 Nutshell 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.

What you can sync between Easypost and Nutshell

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.

Easypost objects Nutshell objects How this pairing syncs
CarrierAccount Carrier credentials and settings that control which carriers and negotiated rates are available; create, update, and delete to manage enabled carriers across accounts. Companies Account records that group people and leads for account-level syncs CarrierAccount is specific to Easypost and Companies to Nutshell — each maps to any object or custom field on the other side.
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. Activities Logged calls, meetings, and emails used for engagement reporting Webhook is specific to Easypost and Activities to Nutshell — each maps to any object or custom field on the other side.
Shipment The central writable object: create with a to/from Address and Parcel, receive Rate options, then buy a label to get postage_label and tracking_code; retrieve and list with cursor pagination. Tasks Rep to-dos mirrored into external work-management or reporting systems Shipment is specific to Easypost and Tasks to Nutshell — each maps to any object or custom field on the other side.
Address Origin and destination locations; create, retrieve, and list, plus address verification (delivery and residential) to normalize and validate addresses before they are saved downstream. Notes Free-text history attached to leads and contacts, replicated for a full timeline Address is specific to Easypost and Notes to Nutshell — each maps to any object or custom field on the other side.

Products Line items attached to leads, used to sync sold products into billing Parcel is specific to Easypost and Products to Nutshell — each maps to any object or custom field on the other side.
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. Tags Segmentation labels mapped to lists or filters in downstream tools Rate is specific to Easypost and Tags to Nutshell — each maps to any object or custom field on the other side.

How changes propagate between Easypost and Nutshell

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.

Easypost Nutshell Sub-second propagation

DetectionEasypost notifies Stacksync of record changes through webhook events. Webhooks deliver an Event via HTTP POST on object changes (e.g.

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

Nutshell Easypost Sub-second propagation

Rate-limit considerations

  • 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.
  • Nutshell: Subject to the platform's API rate limits.
