Incorrect Transaction Data in API and Payment Callbacks

Update timeline

1. identified Oct 07, 2026, 08:45 AM UTC

   We have identified an issue affecting our transaction endpoint and payment callbacks, which may cause incorrect transaction data to be returned and could impact reconciliation. We are treating this issue with high priority and are actively working on a fix. We will provide an update as soon as the issue has been resolved and the endpoint is returning the correct data. Once resolved, we will also re-send affected callbacks to ensure that the correct transaction data is received. We apologize for the inconvenience and will keep you informed of our progress.

   Update: We have identified the affected endpoints and callbacks and are deploying a fix as soon as possible. The following are currently impacted: * GET /api/transactions * May return duplicate transactions * GET /api/transactions/{transactionId} * POST /api/transactions/details * May return incorrect paymentReference and paymentDate * GET /api/payments/{paymentId} * May return incorrect relatedTransactions * PAYMENT_STATUS_CHANGED and PAYOUT_* callbacks * May contain incorrect relatedTransactions * Manual callback resends are affected as well We are treating this with high priority and will provide another update once the fix has been deployed and we have confirmed that the affected endpoints and callbacks are returning the correct data.

   A fix has been deployed and the affected API endpoints and callbacks are now returning the correct data. The issue affected the association between transactions and payments in organizations with multiple card accounts. This could result in duplicate transactions being returned, incorrect paymentReference or paymentDate values, or incorrect relatedTransactions in payment data and callbacks. The underlying transactions and payments themselves were not affected. We will share guidance on recommended actions and ways to mitigate the impact in an upcoming update within the next few minutes. We continue to monitor the fix and will provide a final update once the callback resends have been completed.

4. resolved Oct 07, 2026, 11:30 AM UTC

   The issue has been resolved. The fix is live in production, and the affected API endpoints are returning the correct data. We have also completed the resend of affected PAYMENT_READY and PAYMENT_STATUS_CHANGED callbacks with the corrected data. The underlying transactions and payments themselves were not affected. Recommended actions: * Real-time API usage without storing data: No action is required. New API requests return the correct data. * Stored, cached, or periodically imported transaction data: We recommend re-fetching the transaction data to replace any potentially affected data. * Payment callbacks: No action is required. The affected callbacks have been re-sent with the corrected data. * Data already processed downstream: We recommend re-fetching the data from Pliant and reconciling downstream records against the corrected data. Please contact us if you need assistance with re-syncing or reconciliation. We apologize for the inconvenience caused.
