Payout Webhooks

Endpoint contract

We POST to your registered callback_url:

POST <your callback_url>
Content-Type: application/json

We send JSON only.
We never include a query string.
We do not follow redirects.
Respond with any 2xx status code to acknowledge receipt. Any other response (including 3xx) is treated as a failure and retried.

Headers

Header	Value
`Content-Type`	`application/json`
`User-Agent`	`GifQ-Webhooks/1.0`
`X-Gifq-Event`	The event name. Also present as `event` in the body.
`X-Gifq-Delivery`	UUID unique to this delivery attempt. Use this to deduplicate retries.
`X-Gifq-Timestamp`	Unix epoch seconds at dispatch time.

Delivery guarantees

🚧
At-least-once delivery
A single event may be delivered more than once if your acknowledgement is delayed or fails. Always deduplicate on X-Gifq-Delivery.

Up to 8 attempts. Failed deliveries are retried with exponential backoff. After the final attempt, the event is marked permanently failed and can be re-sent from the GifQ dashboard.
Ordering is not guaranteed. Use occurred_at on the body to resolve out-of-order arrivals.
Terminal events supersede intermediate ones. Once payout.terminal_state is sent for a external_send_id, any pending payout.status_changed for the same send is dropped — you will not see stale intermediate states after the terminal event.

Common body fields

Every event body carries these fields. Event-specific additions are listed under each event below.

Name	Type	Value
`event`	String	The event name. One of `payout.quote_created`, `payout.quote_confirmed`, `payout.quote_canceled`, `payout.status_changed`, `payout.terminal_state`.
`payout_order_uuid`	String	UUID of the payout order this event belongs to. Stable across retries.
`recipient_email`	String	Email of the recipient whose payout this event describes.
`status`	String	Current status of the underlying send. See Status values.
`occurred_at`	String	ISO-8601 timestamp at which the event was generated.
`external_send_id`	String	Identifier for the underlying crypto send. A single recipient can produce multiple `external_send_id`s if a quote expires and is reopened — treat each one as a separate lifecycle.
`tx_hash`	String (optional)	Present on `payout.terminal_state` once a `completed` send is confirmed on chain. Omitted otherwise.
`failure_reason`	String (optional)	Present on `payout.terminal_state` when `status == "failed"`. Omitted otherwise.
`data`	Hash (optional)	Full send-request snapshot — FX rate, fees, ledger account, beneficiary wallet, blockchain transactions. Present on `payout.quote_*` and `payout.terminal_state` events; omitted on `payout.status_changed`. See `data` shape.

Events

`payout.quote_created`

The recipient has selected a currency and network and an FX quote has been issued. This is the earliest event you receive for a given external_send_id.

Name	Type	Value
common fields		See Common body fields.
`data`	Hash	Quote details. See `data` shape.

📘
No duplicates on retry
Idempotent retries of the underlying quote action do not produce duplicate payout.quote_created events for the same external_send_id.

`payout.quote_confirmed`

The recipient confirmed the FX exchange on a cross-currency quote. Fires only when an FX exchange actually occurred — same-currency quotes do not produce this event.

Name	Type	Value
common fields		See Common body fields.
`data`	Hash	`{ "remote": <confirm response> }`.

`payout.quote_canceled`

The recipient canceled an open quote. The same external_send_id cannot be re-confirmed; a subsequent quote produces a new external_send_id and a fresh payout.quote_created.

Name	Type	Value
common fields		See Common body fields.
`data`	Hash	`{ "remote": <cancel response> }`.

`payout.status_changed`

A non-terminal status change on the underlying send. You may see one or more of these between payout.quote_created and payout.terminal_state. Treat occurred_at as authoritative for ordering.

Name	Type	Value
common fields		See Common body fields.

{
  "event": "payout.status_changed",
  "status": "processing",
  "occurred_at": "2026-05-25T10:01:32Z",
  "recipient_email": "[email protected]",
  "external_send_id": "123456",
  "payout_order_uuid": "11111111-2222-3333-4444-555555555555"
}

`payout.terminal_state`

The underlying send has reached a terminal status (completed, failed, expired, or canceled). You receive at most one payout.terminal_state per external_send_id.

🚧
tx_hash may arrive on a follow-up event
If a send is completed but the on-chain transaction has not yet confirmed at dispatch time, tx_hash is omitted. A second payout.terminal_state for the same external_send_id may follow once the hash lands — treat the later event as authoritative for tx_hash.

Name	Type	Value
common fields		See Common body fields.
`tx_hash`	String (optional)	Present when `status == "completed"` and the on-chain confirmation has landed.
`failure_reason`	String (optional)	Present when `status == "failed"`.

  "failure_reason": "insufficient_funds"
}

Status values

`status`	Meaning
`in_progress`	The send request has been accepted. No funds have moved yet.
`processing`	The send is being processed. An FX exchange may be in flight or the chain broadcast is pending.
`completed`	The send is finalized. If `tx_hash` is present, funds are confirmed on chain.
`failed`	The send did not go through. `failure_reason` carries the cause.
`expired`	The send was not actioned within its lifetime window.
`canceled`	The send was canceled. No funds moved.

completed, failed, expired, and canceled are terminal — no further events fire for that external_send_id once a terminal event has been sent.

`data` shape

data is present on payout.quote_* events and on payout.terminal_state events. It carries the full send-request snapshot at the moment the event was generated.

Field	Type	Notes
`id`	Integer	Send-request ID. Equals `external_send_id` parsed as integer.
`status`	String	Current status of the underlying send. Mirrors the top-level `status`.
`purpose`	String	Human-readable description of the payout.
`created_at`	String	ISO-8601 timestamp when the send request was created.
`input_amount`	String	Amount the recipient is sending, in `input_currency`.
`input_currency`	Hash	See Currency object.
`sending_amount`	String	Amount the recipient will receive, in `sending_currency`.
`sending_currency`	Hash	See Currency object.
`input_to_sending_rate`	String	FX rate used to convert `input_amount` to `sending_amount`. `"1.0"` for same-currency sends.
`balance_debit_amount`	String	Amount debited from the merchant's ledger, in `balance_debit_currency`.
`balance_debit_currency`	Hash	See Currency object.
`sending_to_balance_debit_rate`	String	FX rate used to convert from `sending_currency` to `balance_debit_currency`.
`fees.service_fee`	Hash	`{ amount, currency }`. `amount` is a decimal string; `currency` follows the Currency object shape.
`fees.conversion_fee`	Hash	`{ amount, currency }`. Only present on cross-currency sends.
`ledger_account`	Hash	`{ id, title, status, balance, account_type, currency }`. The merchant ledger account funds were debited from.
`beneficiary_payout_setting`	Hash	`{ id, beneficiary_id, created_at, currency, platform, crypto_address, crypto_address_metadata }`. The destination wallet for this send.
`blockchain_transactions`	Array	Empty `[]` until the chain broadcast lands. Once populated, each entry is `{ id, txid, amount, status, network_confirmations, currency }`. The `txid` of the first entry is surfaced at the top level as `tx_hash` on `payout.terminal_state`.
`requires_2fa_confirmation`	Boolean	Whether the recipient must complete 2FA before the send proceeds.

Currency object

input_currency, sending_currency, balance_debit_currency, and the currency nested under fees.* / ledger_account / beneficiary_payout_setting all share the same shape:

Field	Type	Notes
`id`	Integer	Internal currency ID.
`kind`	String	`"fiat"` or `"crypto"`.
`title`	String	Full currency name (e.g. `"Ethereum"`, `"USDC"`).
`symbol`	String	Ticker symbol (e.g. `"ETH"`, `"USDC"`).
`enabled`	Boolean	Whether the currency is currently enabled for new sends.
`disabled_message`	String (optional)	Reason a disabled currency is unavailable. `null` when `enabled: true`.

BlockchainTransaction object

Entries in data.blockchain_transactions[] describe individual on-chain transactions backing the send. The array is empty until the chain broadcast lands; once populated, the txid of the first entry is surfaced at the top level as tx_hash on payout.terminal_state.

Field	Type	Notes
`id`	Integer	Internal transaction ID.
`txid`	String	On-chain transaction hash.
`amount`	String	Decimal amount transferred in this transaction.
`status`	String	Transaction status (e.g. `"confirmed"`).
`network_confirmations`	Integer	Number of confirmations the transaction has received.
`currency`	Hash	A thinner variant of the Currency object: `{ id, title, symbol, platform: { id, title } }`. The nested `platform` identifies the chain the transaction was broadcast on (e.g. `"Base"`, `"Solana"`, `"Ethereum"`).

Example:

{
  "id": 7000001,
  "txid": "0x1111111111111111111111111111111111111111111111111111111111111111",
  "amount": "12.0",
  "status": "confirmed",
  "network_confirmations": 1,
  "currency": {
    "id": 113,
    "title": "USDC",
    "symbol": "USDC",
    "platform": {
      "id": 42,
      "title": "Base"
    }
  }
}

📘
Decimal amounts are strings
All amounts are decimal strings — parse with your language's arbitrary-precision decimal type, not floats. Additional fields may appear in data; treat unknown fields as informational.

Receiving in your handler

Recommended order:

Deduplicate on X-Gifq-Delivery.
Handle the event.
Acknowledge with 2xx only after durable persistence.

post '/gifq/webhooks' do
  body = JSON.parse(request.body.read)
  delivery_id = request.env['HTTP_X_GIFQ_DELIVERY']
  return status 204 if already_handled?(delivery_id)

  case body['event']
