INVOICE_ALREADY

This invoice is already voided; voiding cannot be repeated

Category: Invoices


HTTP status	`409` Conflict
Retry	No

When it happens

The invoice was already voided, by an earlier call (a retry after a timeout, or two clients voiding at once) or from the dashboard.

How to fix it

Treat it as done: the invoice is voided, which is what you asked for. Send an Idempotency-Key on the void call if you want a retry to replay the original success instead.

Retry

Do not retry. The outcome is final: sending the same request again gets the same answer.
