Why teams connect Navan and Seismic

Sync customers, invoices, and payment status between Navan 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. Navan 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 Bookings, Custom Fields, Receipts, Repayments, Fees, and Adjustments in Navan to Users, User Groups, Teamsites, LiveSend Links 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 Push coded expense transactions into an accounting system, then set their ERP sync status in Navan so the same records are not exported twice.
  • 02 Pull Bookings by date range into a database to reconcile travel reservations against Card Transactions and monitor travel-policy spend.
  • 03 Provision and deactivate Seismic Users and User Groups from an HRIS or IdP so content access mirrors joiner, mover, and leaver changes.
  • 04 Extract content-interaction and LiveSend engagement from the Reporting API v2 into a warehouse to tie asset views to CRM Opportunities.

Common sync patterns

Payment status on the account

Invoice and payment status from Navan appears on the account in Seismic, so reps see overdue balances before they promise the next order.

Billing detail changes flow back

When a contact or address is corrected in Seismic, Navan 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.

What you can sync between Navan 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.

Navan objects Seismic objects How this pairing syncs
Users Employee and cardholder records referenced by every transaction; usually provisioned from an HRIS and used to map spend to people and departments. 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.
Bookings Flight, hotel, rail, and car reservations from the Booking API; pulled read-only by createdFrom/createdTo date range for trip and travel-spend reporting. Digital Sales Rooms Buyer-facing microsites (DSRs); lifecycle and content-change events surface via webhooks, currently marked Early Access. Bookings is specific to Navan and Digital Sales Rooms to Seismic — each maps to any object or custom field on the other side.
Custom Fields Company metadata such as cost centers and project codes; discovered via GET and their option lists created or updated via async POST. Reporting Activities Content-interaction, engagement, and usage analytics extracted read-only through the ETL-oriented Reporting API v2 for a warehouse. Custom Fields is specific to Navan and Reporting Activities to Seismic — each maps to any object or custom field on the other side.
Receipts Receipt images tied to each transaction; fetched read-only through presigned URLs for archival in a warehouse or document store. Library Content Documents, decks, and assets stored in teamsites; created, moved, and retrieved via the Content Management API, each with a contentId. Receipts is specific to Navan and Library Content to Seismic — each maps to any object or custom field on the other side.
Repayments, Fees, and Adjustments Money-movement records including repayments, FX and platform fees, and credit or debit memos; read-only for reconciliation ledgers. Content Versions Version history for a library item; new versions upload via API and old ones expire, with events firing on ContentManager webhooks. Repayments, Fees, and Adjustments is specific to Navan and Content Versions to Seismic — each maps to any object or custom field on the other side.
Card Transactions Navan physical and virtual card spend; read via GET, then GL codes, cost centers, and ERP sync status are written back per transaction through the transaction update endpoint. User Groups Group definitions and membership that govern content access; synced from an IdP or HRIS to keep permissions current. Card Transactions is specific to Navan and User Groups to Seismic — each maps to any object or custom field on the other side.

How changes propagate between Navan 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.

Navan Seismic Sub-second propagation

DetectionNavan notifies Stacksync of record changes through webhook events. Navan's Expense API supports webhooks for transaction and expense events.

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

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

Rate-limit considerations

  • Navan: Requests are throttled with HTTP 429 and Navan recommends retrying with exponential backoff; the Expense/Public API must first be enabled per account by Navan.
  • 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 Navan and Seismic connectors work

Navan

Integration surface
REST (Expense API and Booking API)
Authentication
OAuth 2.0 client-credentials flow; an admin creates a client_id and client_secret under Settings > Integrations and exchanges them at Navan's OAuth token endpoint for a short-lived bearer token that is refreshed on expiry (separate US and EU regional hosts)
Change detection
Navan's Expense API supports webhooks for transaction and expense events; sync engines also poll GET endpoints with date-range and updatedAt filters (createdFrom/createdTo for bookings) to backfill history and reconcile. There is no database-level CDC.
