For: Anyone needing to reference, investigate, or reconcile a payment processed through Prommt.
What is a Transaction ID?
A Transaction ID (sometimes called a Gateway Reference or PSP Reference) is the unique identifier assigned to a payment by your payment gateway — Adyen, FreedomPay, or similar. It's the reference your gateway uses to track the transaction on their side.
You'll need the Transaction ID when:
Raising a support query with your payment gateway about a specific transaction
Investigating a failed or disputed payment
Reconciling payments between Prommt and your gateway's reporting
Responding to a chargeback — the gateway will ask for this reference when you submit evidence
Contacting Prommt Support about a payment issue
Finding the Transaction ID in Prommt
Step 1 — Go to View Payments
From your Prommt dashboard, click View Payments in the left-hand navigation.
Step 2 — Find the payment
Use the search, date filter, or status filter to locate the payment. Click on it to open the full payment detail screen.
Step 3 — Find the Transaction ID
On the payment detail screen, look for the Payment Gateway Response section. The Transaction ID or Gateway Reference will be displayed here alongside the response code from your gateway.
The exact label varies slightly by gateway:
Gateway | Label shown in Prommt |
Adyen | PSP Reference |
FreedomPay | Transaction ID |
Other gateways | Gateway Reference or Transaction ID |
Copy this reference before contacting your gateway or Prommt Support — it's the fastest way to locate the transaction on either side.
Finding the Transaction ID in your gateway portal
Once you have the Transaction ID from Prommt, you can use it to locate the transaction directly in your payment gateway's portal.
Log into your gateway portal and use the transaction search or reporting area to look up the reference. The Transaction ID from Prommt will match exactly what your gateway has on record — use it to pull up the full transaction detail, including authorisation status, card details, and 3DS authentication outcome.
If you're unsure how to navigate your gateway portal, contact your gateway provider directly — they can guide you to the right area for transaction lookups.
Finding the Transaction ID on exported payment data
If you're working from a CSV export rather than the dashboard:
Go to View Payments
Apply your filters (date range, location, status)
Click Export
Open the CSV — the Transaction ID or Gateway Reference appears as a dedicated column in the export
This is useful for bulk reconciliation — the Transaction ID column lets you match Prommt payment records directly to your gateway's transaction report.
If the Transaction ID is missing or blank
A missing Transaction ID on a payment record means the transaction did not reach the gateway — the payment failed before a gateway reference was assigned. This typically indicates:
The customer abandoned the checkout before completing payment
A gateway connectivity issue prevented the transaction from being submitted
If a payment you expected to go through has no Transaction ID and shows as failed, see Troubleshooting: all payments failing on your account or Troubleshooting: individual card declines and payment failures.
