Why teams connect Couchbase and Easypost

Give your engineers Easypost's products, orders, and customers in Couchbase: read them with normal queries, write inventory and prices back through the sync, and skip the storefront API.

E-commerce data sits behind an API built for the storefront, not for your internal systems. Teams that need those records, for order routing, inventory logic, reporting, or back-office tools, end up writing integration code against a rate-limited API and maintaining it through every catalog change and platform upgrade.

Stacksync mirrors CarrierAccount, Webhook, Shipment, Address from Easypost into Couchbase and keeps both sides consistent in real time. Whatever Easypost holds, whether products, orders, customers, or inventory, those records become rows your code can query, and changes written in Couchbase, such as new prices, stock levels, or fulfillment status, sync back into Easypost with its validations respected.

Merchandising and operations keep working in the storefront, engineers keep working in the database, and neither side has to reconcile against a nightly export.

Common use cases

  • 01 Stream document mutations via DCP into downstream systems so caches, search indexes, or warehouses stay current.
  • 02 Two-way sync between Couchbase (serving application data) and a CRM so support and sales teams see live application state.
  • 03 Batch-create and buy labels for a day's orders, generate a ScanForm, and write each label and tracking code back into the fulfillment system.
  • 04 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.

Common sync patterns

Internal tools and automations without API code

Scripts and services read and write the synced tables; Stacksync handles the Easypost API, rate limits, and retries.

React to store changes

Updates in Easypost arrive as row changes in Couchbase, so jobs and triggers can respond the moment an order, price, or stock level changes.

Keep catalog and inventory current

Prices, stock levels, or product details maintained in Couchbase sync back onto Easypost, so the storefront shows what your systems treat as true.

What you can sync between Couchbase 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.

Couchbase objects Easypost objects How this pairing syncs
XDCR replications Cluster-to-cluster replication streams, useful context when choosing a sync source cluster. 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. XDCR replications is specific to Couchbase and Tracker to Easypost — each maps to any object or custom field on the other side.
Full-text search indexes Search indexes over documents, relevant when syncing searchable content. 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. Full-text search indexes is specific to Couchbase and Batch to Easypost — each maps to any object or custom field on the other side.
Buckets Top-level data containers, roughly analogous to a database, that scope replication and memory quotas. CarrierAccount Carrier credentials and settings that control which carriers and negotiated rates are available; create, update, and delete to manage enabled carriers across accounts. Buckets is specific to Couchbase and CarrierAccount to Easypost — each maps to any object or custom field on the other side.
Scopes Namespaces inside a bucket used to group collections, similar to schemas. 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. Scopes is specific to Couchbase and Webhook to Easypost — each maps to any object or custom field on the other side.
Collections Table-like groupings of documents that syncs typically map one-to-one to destination tables. 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. Collections is specific to Couchbase and Shipment to Easypost — each maps to any object or custom field on the other side.
JSON Documents The core records; schemaless JSON keyed by document id, flattened or mapped to relational rows in syncs. 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. JSON Documents is specific to Couchbase and Address to Easypost — each maps to any object or custom field on the other side.

How changes propagate between Couchbase 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.

Couchbase Easypost Sub-second propagation

DetectionChanges in Couchbase are captured at the source via change data capture — no polling loop against its API. Database Change Protocol (DCP) streams document mutations.

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

Easypost Couchbase 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 applied to Couchbase as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • Couchbase: Throughput is bounded by cluster sizing rather than 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.
