Why teams connect Easypost and Streak CRM

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

Streak CRM 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 Contacts, Organizations, Tasks, Email threads in Streak CRM to Shipment, Address, Parcel, Rate 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 Push deals and contacts into a warehouse to report on pipeline alongside product and billing data
  • 02 Hand off closed-won boxes to billing or fulfillment systems and sync status back into the pipeline
  • 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

New buyers become CRM records

A customer created in Easypost creates or updates the matching contact or account in Streak CRM, so first-time and repeat buyers land in the relationship system without a manual import.

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 Streak CRM segments customers: status travels to the store record

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

What you can sync between Easypost and Streak CRM

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 Streak CRM objects How this pairing syncs
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. Organizations Company records associated with contacts and boxes. Shipment is specific to Easypost and Organizations to Streak CRM — 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. Tasks To-dos attached to boxes for follow-up tracking. Address is specific to Easypost and Tasks to Streak CRM — each maps to any object or custom field on the other side.
Parcel Package dimensions and weight (or a predefined_package); created standalone or inline on a Shipment and reused across shipments and batches. Email threads Gmail threads linked to boxes, since the CRM lives inside the inbox. Parcel is specific to Easypost and Email threads to Streak CRM — 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. Custom fields Per-pipeline field definitions that determine what data a box can hold. Rate is specific to Easypost and Custom fields to Streak CRM — each maps to any object or custom field on the other side.
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. Pipelines Define the process and the custom field schema that boxes in them carry. Tracker is specific to Easypost and Pipelines to Streak CRM — each maps to any object or custom field on the other side.
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. Boxes The core record (a deal, hire, or project) tracked through pipeline stages. Batch is specific to Easypost and Boxes to Streak CRM — each maps to any object or custom field on the other side.

How changes propagate between Easypost and Streak CRM

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 Streak CRM 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 Streak CRM through its API, with automatic retries and rate-limit backoff.

Streak CRM Easypost Interval-based propagation

DetectionStacksync polls Streak CRM for changes on an incremental schedule, reading only records changed since the previous pass. Polling against pipeline, box, and contact endpoints.

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

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.
  • Streak CRM: Subject to the platform's API rate limits; quotas are not prominently published.
