Why teams connect Easypost and Ramp

Turn every Easypost order into clean revenue: Ramp and Easypost keep customers, orders, and payment status aligned in real time, in both directions.

Easypost runs the storefront — the catalog, the orders, and the buyers placing them. Ramp records the money behind those orders — invoices, revenue, payments, and the ledger the business closes on. The overlap is every customer, order, and product both sides need to agree on, and when that overlap is bridged by CSV export or an overnight batch, finance reconciles against stale numbers while the store quotes prices or stock the books no longer recognize.

Stacksync syncs Departments, Reimbursements, Bills, Vendors in Ramp with Webhook, Shipment, Address, Parcel in Easypost field by field, in real time, and in both directions. You decide which system owns which fields — an order's totals from Easypost, its paid-or-overdue state from Ramp — and Stacksync keeps every copy consistent and resolves conflicts by the rules you set.

The result is one shared record of who bought what and whether it has been paid, so the storefront, support, and the finance team all read from the same current data instead of re-keying it between systems.

Common use cases

  • 01 Two-way sync Transactions and their accounting codings with a Postgres warehouse so finance analyzes spend in SQL and pushes GL categories and memos back to Ramp.
  • 02 Mirror Bills and their approval and payment state into an AP or ERP system, marking each one ready-to-sync then synced to keep both ledgers reconciled.
  • 03 Pull Shipment, Rate, and Refund records into a warehouse to report shipping cost per carrier and service and reclaim postage on labels that were never scanned.
  • 04 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.

Common sync patterns

Where Easypost originates orders: sales flow into the books

A new or updated order in Easypost creates or updates the matching invoice or revenue record in Ramp, so billing and reporting start without re-entry.

Where Ramp is the money system of record: payment status on the order

Paid, overdue, and refunded state from Ramp lands on the order or account in Easypost, so the store and support see what has actually been collected.

One customer master

Where both systems keep customer or buyer records, an edit in either propagates to the other, ending duplicate accounts and mismatched contact details.

What you can sync between Easypost and Ramp

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 Ramp objects How this pairing syncs
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. General Ledger Accounts Chart-of-accounts entries uploaded from the ERP; accounting codings are posted back against transactions and bills. Webhook is specific to Easypost and General Ledger Accounts to Ramp — 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. Transactions Card purchase records with merchant, amount, and state; read for spend/GL sync and written back via accounting codings and sync status. Shipment is specific to Easypost and Transactions to Ramp — 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. Cards Physical and virtual card records; created and managed through the API to provision or suspend cardholder spend. Address is specific to Easypost and Cards to Ramp — 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. Users Employee and cardholder records; invited, updated, and deactivated, commonly synced from an HRIS or identity provider. Parcel is specific to Easypost and Users to Ramp — 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. Departments Org groupings for cost-center and GL allocation; pushed from an ERP/HRIS and referenced by cards and transactions. Rate is specific to Easypost and Departments to Ramp — 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. Reimbursements Out-of-pocket expense claims; read for reporting and marked ready-to-sync then synced to the ERP. Tracker is specific to Easypost and Reimbursements to Ramp — each maps to any object or custom field on the other side.

How changes propagate between Easypost and Ramp

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

Ramp Easypost Sub-second propagation

DetectionRamp notifies Stacksync of record changes through webhook events. Signed webhooks (HMAC-SHA256 X-Ramp-Signature) for bill, transaction, reimbursement, vendor, and user events.

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.
  • Ramp: 200 requests per 10-second rolling window per source IP; exceeding it returns 429 Too Many Requests, and requests running over 60 seconds return 504. Results use keyset pagination (follow the page.next URL / start cursor); higher limits can be requested from support.

Ramp

Integration surface
REST API (Developer API v1)
Authentication
OAuth 2.0: exchange client_id/client_secret (HTTP Basic) at api.ramp.com/developer/v1/token for scoped bearer tokens; client_credentials grant for server-to-server and authorization_code for user-delegated access; scopes follow resource:permission (e.g. transactions:read, bills:write, accounting:write).
Change detection
Signed webhooks (HMAC-SHA256 X-Ramp-Signature) for bill, transaction, reimbursement, vendor, and user events; otherwise poll incrementally (synced_after on transactions, from_created_at on bills) with keyset pagination, or read the audit-logs/events feed.
