IdempotencyInProgress 409
When you get it
A request with the same Idempotency-Key is still running. This stops two concurrent retries from paying twice.
Example
{
"_tag": "IdempotencyInProgress",
"type": "IdempotencyInProgress",
"message": "A request with this Idempotency-Key is still being processed.",
"docs_url": "https://apidocs.borderli.io/docs/errors/IdempotencyInProgress"
}
What to do
Wait a moment and send the same request again, same key and same body. Once the first one finishes you get its response. See Idempotency.
