Create a developer app in Ramp via Settings > Developer to obtain API credentials; admin access is required to create the app
Authenticate using OAuth 2.0 and request the scopes needed to read transactions and accounting data
GET transactions from the transactions endpoint, filtering by date range and optionally by sync_status to retrieve only records that are ready to sync to accounting
Extract fields including amount, currency, merchant_name, merchant category, and any accounting fields such as GL account and cost center coded by the cardholder
Write the records to your ERP or accounting system, then mark them as synced via the accounting sync endpoint to prevent duplicate processing in subsequent pulls
Use the Ramp webhook system to subscribe to transaction events and trigger incremental syncs rather than relying solely on scheduled batch pulls
Known gotchas
Transactions in a pending state do not yet have a final settled amount; always filter on settled or sync-ready status before posting to a ledger to avoid reversals
Ramp merchant category data may not always map cleanly to travel MCCs; implement a fallback classification layer for edge cases where merchant_name is more reliable than the category code
The sync_status field is designed to prevent double-posting; resetting it incorrectly or bypassing it with raw date-range queries can result in duplicate journal entries
