Why teams connect Coupa and Ramp

Keep the customer, invoice, and payment records that Coupa and Ramp share consistent in real time, whether the two systems split your finance stack or one is replacing the other.

Two finance systems in one company usually means one of two setups. Either the systems divide the work, with one issuing invoices or serving a business unit while the other holds the books, or one is on its way out and both must stay accurate during the transition. In both cases, the customer, invoice, and payment records the two systems share start to drift the moment updates are keyed twice or moved by hand.

Stacksync syncs Invoices, Suppliers, Users, Accounts in Coupa with Cards, Users, Departments, Reimbursements in Ramp bi-directionally and in real time. A record created or corrected in either system appears in the other within seconds, with field-level mapping and conflict resolution in place of CSV exports and nightly batch jobs.

That matters most at close. When both systems agree on who was billed, what was paid, and what is outstanding, reconciliation stops being a hunt for which copy of the truth is current.

Common use cases

  • 01 Push chart-of-accounts segments and cost centers from the ERP into Coupa Accounts so Requisitions and Invoices code to the right GL.
  • 02 Provision and update Users in Coupa from an HRIS or identity provider as employees join, change roles, or leave.
  • 03 Read Reimbursements into a finance database for cross-entity expense reporting and reconciliation without manual CSV exports.
  • 04 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.

Common sync patterns

Parallel run during a migration

When one system is replacing the other, keep both live and matching through the cutover, so no transaction falls between the last export and go-live.

One customer master

A customer's name, billing details, or payment terms corrected in either system update the other immediately, so the next invoice always uses current information.

Payment status everywhere

A payment applied in one system updates the matching invoice in the other, so no one chases a balance that was already settled.

What you can sync between Coupa 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.

Coupa objects Ramp objects How this pairing syncs
Users Employee and user accounts with roles and content groups; provisioned and updated from an HRIS or identity provider. Users Employee and cardholder records; invited, updated, and deactivated, commonly synced from an HRIS or identity provider. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Accounts Chart-of-accounts segments and GL codes; usually mastered in the ERP and written into Coupa so requisitions and invoices code correctly. Cards Physical and virtual card records; created and managed through the API to provision or suspend cardholder spend. Accounts is specific to Coupa and Cards to Ramp — each maps to any object or custom field on the other side.
Contracts Supplier contract records with terms and dates; read out for reporting or created from a CLM system. Departments Org groupings for cost-center and GL allocation; pushed from an ERP/HRIS and referenced by cards and transactions. Contracts is specific to Coupa and Departments to Ramp — each maps to any object or custom field on the other side.
Expense Reports Employee expense reports and their lines; exported to AP or ERP for reimbursement and GL posting. Reimbursements Out-of-pocket expense claims; read for reporting and marked ready-to-sync then synced to the ERP. Expense Reports is specific to Coupa and Reimbursements to Ramp — each maps to any object or custom field on the other side.
Requisitions Employee purchase requests with lines and approval chains; read out to warehouses, or created via the API from upstream intake tools. Bills Accounts-payable bills; created, updated, approved, and paid, then posted ready-to-sync and synced to accounting. Requisitions is specific to Coupa and Bills to Ramp — each maps to any object or custom field on the other side.
Purchase Orders PO headers and lines; synced two-way with ERPs so orders raised in Coupa flow to the ledger and status updates flow back on the /purchase_orders resource. Vendors Supplier records under the accounting namespace; uploaded and updated for AP matching and payments. Purchase Orders is specific to Coupa and Vendors to Ramp — each maps to any object or custom field on the other side.

How changes propagate between Coupa 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.

Coupa Ramp Interval-based propagation

DetectionStacksync polls Coupa for changes on an incremental schedule, reading only records changed since the previous pass. Polling on updated-at and created-at filters (e.g.

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

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

Rate-limit considerations

  • Coupa: Coupa does not publish explicit rate limits or expose X-RateLimit/Retry-After headers; integrations page 50 records at a time and back off on 429/503 responses.
  • 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.

How the Coupa and Ramp connectors work

Coupa

Integration surface
REST Core API (JSON or XML)
Authentication
OAuth 2.0 / OIDC via the client-credentials grant; scopes take the service.object.right form (e.g. core.accounting.read, core.accounting.write). Legacy API keys are being retired (no new keys since R34; API-key auth unsupported from R36). Access tokens last 24 hours.
Change detection
Polling on updated-at and created-at filters (e.g. updated-at[gt]=<timestamp>); Coupa has no native webhook subscriptions, though admins can configure outbound Call Out / external notifications.

Rate limits
Coupa does not publish explicit rate limits or expose X-RateLimit/Retry-After headers; integrations page 50 records at a time and back off on 429/503 responses.

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.
