Error message

Cannot update a transaction while a payment attempt is in progress.

Common causes

• An asynchronous payment, like UPI or Pix, is pending for this transaction. Paddle locks the transaction until the payment succeeds or fails.

Troubleshooting

• Wait for the payment attempt to finish, then retry the update. Subscribe to the transaction.updated webhook, or poll the transaction, and retry once the in-progress payment has resolved.
