Why teams connect Ramp and Seismic

Sync customers, invoices, and payment status between Ramp and Seismic in real time, so sales sees the money and finance sees the relationship.

Finance and sales describe the same customers in different systems. Seismic knows the relationship: who the contacts are and what is in motion with the account. Ramp knows the money: what was invoiced, what was paid, what is overdue. When the two are connected only by exports, each side works partly blind.

Stacksync links Cards, Users, Departments, Reimbursements in Ramp to LiveSend Links, Digital Sales Rooms, Reporting Activities, Library Content in Seismic with bi-directional, real-time sync. New customers, updated billing details, invoice status, and payment activity move in whichever direction you configure, field by field, with conflicts resolved by rules you set. The result is one version of each customer, visible from both sides.

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 React to ContentManager and DSR webhook events to update a database when documents are published, versioned, or expired.
  • 04 Provision and deactivate Seismic Users and User Groups from an HRIS or IdP so content access mirrors joiner, mover, and leaver changes.

Common sync patterns

Billing detail changes flow back

When a contact or address is corrected in Seismic, Ramp gets the update before the next invoice goes out.

Collections with context

Finance sees the account owner and relationship history from Seismic when chasing a balance, and sales sees that the chase is happening.

Where Seismic tracks deals: closed-won creates the finance record

A won opportunity creates or updates the customer in Ramp with the right billing details, so invoicing starts without re-keying.

What you can sync between Ramp and Seismic

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.

Ramp objects Seismic objects How this pairing syncs
Users Employee and cardholder records; invited, updated, and deactivated, commonly synced from an HRIS or identity provider. Users User records managed through SCIM 2.0 and legacy user endpoints; created, updated, and deactivated for provisioning sync. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Reimbursements Out-of-pocket expense claims; read for reporting and marked ready-to-sync then synced to the ERP. LiveSend Links Trackable content-share links created via the engagement API; their open and view engagement is read back through Reporting. Reimbursements is specific to Ramp and LiveSend Links to Seismic — each maps to any object or custom field on the other side.
Bills Accounts-payable bills; created, updated, approved, and paid, then posted ready-to-sync and synced to accounting. Digital Sales Rooms Buyer-facing microsites (DSRs); lifecycle and content-change events surface via webhooks, currently marked Early Access. Bills is specific to Ramp and Digital Sales Rooms to Seismic — each maps to any object or custom field on the other side.
Vendors Supplier records under the accounting namespace; uploaded and updated for AP matching and payments. Reporting Activities Content-interaction, engagement, and usage analytics extracted read-only through the ETL-oriented Reporting API v2 for a warehouse. Vendors is specific to Ramp and Reporting Activities to Seismic — each maps to any object or custom field on the other side.
Funds (Spend Controls) Spend controls governing card usage; read and created via the funds API to enforce budgets per user, department, or program. Library Content Documents, decks, and assets stored in teamsites; created, moved, and retrieved via the Content Management API, each with a contentId. Funds (Spend Controls) is specific to Ramp and Library Content to Seismic — each maps to any object or custom field on the other side.
General Ledger Accounts Chart-of-accounts entries uploaded from the ERP; accounting codings are posted back against transactions and bills. Content Versions Version history for a library item; new versions upload via API and old ones expire, with events firing on ContentManager webhooks. General Ledger Accounts is specific to Ramp and Content Versions to Seismic — each maps to any object or custom field on the other side.

How changes propagate between Ramp and Seismic

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.

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

Seismic Ramp Sub-second propagation

DetectionSeismic notifies Stacksync of record changes through webhook events. Webhooks for content, version, user, group, workflow, DSR, and LiveSend events.

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

Rate-limit considerations

  • 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.
  • Seismic: Tiered per-endpoint limits over a rolling 60-second window; exceeding returns HTTP 429, with X-Seismic-Remaining-Calls and X-Seismic-Total-Calls headers.

How the Ramp and Seismic connectors work

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.

Rate limits
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.
