WAL-1214
This idempotency key was already used for a different top-up
Why it happens
The idempotency key idempotencyKey already belongs to an earlier top-up with different details (amount or payment method). A key identifies one operation, so no payment was requested.
What to do
Use a new idempotency key for each new top-up. To repeat the earlier top-up safely, send the same details with the same key.
