In the case that there is a failed step in the sequence of a standing order (i.e. at the swap or withdrawal step), the following webhooks notify you of the failed step and a reason if available. In most cases you might simply have to call the "Resume Standing Order" API or the user may be ineligible for a withdrawal due to their KYC tier.

}- Blocked by Travel Rule
For FIAT_TO_CRYPTO standing orders, Travel Rule is checked after the swap and before the on-chain withdrawal.
If the whitelisted payout address is not Travel Rule–compliant (e.g. undeclared address, pending wallet verification, or missing VASP user info), the flow stops. You still get the pay-in and swap webhooks; payout webhooks are not sent.
Instead you receive:
{
"type": "STANDING_ORDER_FAILED",
"failureType": "BLOCKED_BY_TRAVEL_RULE",
"standingOrderId": "9f00b87f-5a4d-421e-a8eb-fbc7041ccc8e",
"standingOrderSpanId": "71b8e49d-af3e-47f8-9f73-748f49ffcefb",

"sourceSyncedOwnerId": "9957bc9f-a9e8-4edf-ad16-a9f241f961ce",
"ts": 1757681065000
}Funds: The swap completes; crypto stays in the user's wallet.
What to do: Notify the user, declare the counterparty (and complete verification if required)
Tip: Declare and verify the whitelisted address before creating the standing order to avoid this failure.
