Sandbox

Simulate one signer's cosignature for a non-custodial conversion / OFFRAMP source leg

Sandbox-only endpoint that stamps a single signer’s vote against the source leg’s M-of-N signing quorum for a conversion (SWAP / BRIDGE) or OFFRAMP order funded from a non-custodial customer wallet, bypassing the real passkey-approval flow. Each call advances the quorum by one vote: pass signerId to target a specific ACTIVE wallet signer, or omit it to auto-advance to the next signer with no recorded vote (so repeated calls walk 1 of N → 2 of N → completed). The transfer waits for the M-th approval; intermediate approvals leave the request awaiting signatures. A single declined stamp declines the whole quorum. Read incremental progress via GET /v2/verifications/{token} (the quorum block). Once the quorum approves, the transfer confirms automatically in sandbox shortly after — poll GET /v2/orders/{id} until it reaches succeeded. 404 ORDER_NOT_FOUND if the order does not belong to the org or has no source-leg conversion transaction. 404 NOT_IN_AWAITING_SIGNATURE if the source leg is not yet awaiting signatures (poll until it clears) or the order never required signatures — distinct from stamping after the quorum has already approved, which returns 200 with the order at its current state. 404 SIGNER_NOT_FOUND if an explicit signerId is not on the wallet’s active roster. Returns the order at its current state.

lockExpiresAt

string<date-time>

required

Deadline for execution to begin, not merely for the source to be funded. If execution hasn't been claimed by this time, the order transitions to status: cancelled with cancellationReason: 'expired' and can no longer execute — funding the source after this timestamp does not revive it. Create a new order to get a fresh rate lock.

Example:

"2026-01-15T09:30:00.000Z"

createdAt

string<date-time>

required

ISO 8601 timestamp

Example:

"2026-01-15T09:30:00.000Z"

autoExecute

boolean

required

Echoes the create-time value. When true, Conduit automatically claims execution once the available source balance covers totalDebit (principal plus fees), with no client action required — orders sharing the same source resource execute oldest-first, so a still-underfunded older order can delay a newer, already-funded one; when false, the client must call POST /v2/orders/{id}/execute (repeatable after funding if a prior attempt returned 422 INSUFFICIENT_FUNDS). Order creation never checks or reserves the source's available balance regardless of this value.

linkedTransactionIds

string[]

required

Pattern: ^txn_[0-9A-Za-z]{22}$

clientReferenceId

string

Client-supplied reference, unique per resource within your organization. 1-255 characters from A-Za-z, 0-9, underscore, hyphen, colon, and period — no spaces.

Pattern: ^[A-Za-z0-9_\-:.]{1,255}$

source

object

The funding resource, when the order named one. Omitted entirely on a deposit-funded order (created without a source): the funding wallet is Conduit-managed infrastructure with no client-resolvable id, and depositInstructions carries the address to fund at instead. The presence of depositInstructions is the discriminator.

Option 1
Option 2

Show child attributes

autoPayout

object

AutoPayout payload. Crypto recipients omit rail/ach/swift/instant/remittance; fiat (us|swift) recipients require rail and may carry the matching per-rail context block.

Show child attributes

markup

object

Present on an order that declared a margin which comes to at least one minor unit of the source asset. assetAmount is the total accrued to you, fixed at quote time. The two shapes reach the customer differently: the markupBps part is folded into the quoted rate, so it never appears in fees[] and does not move totalDebit, while the markupAmount part is a line item in fees[] owned by you and it does move totalDebit.

Show child attributes

executedAt

string<date-time>

ISO 8601 timestamp

Example:

"2026-01-15T09:30:00.000Z"

executionTrigger

enum<string>

Which path claimed execution: 'client' for a POST /v2/orders/{id}/execute call, 'auto' for automatic execution by Conduit. Set as soon as execution is claimed — well before the order reaches a terminal status — so it can appear on an order that is still status: pending while its conversion is in flight. Absent on an order that hasn't started executing yet (including one cancelled before execution began).

Available options:

client,

auto

cancelledAt

string<date-time>

ISO 8601 timestamp

Example:

"2026-01-15T09:30:00.000Z"

cancellationReason

enum<string>

Available options:

expired,

client_cancelled

failureCode

enum<string>

Available options:

insufficient_funds,

provider_unavailable,

provider_rejected,

internal_error,

cancelled

failureMessage

string

quoteOptionId

string

Present when this order redeemed a POST /v2/quotes option — the id of the option it consumed.

Pattern: ^qop_[0-9A-Za-z]{22}$

depositInstructions

object[]

Where to send funds to fund this order. Exactly one crypto_address block.

Required array length: 1 element

Show child attributes

fundedBy

object[]

Transfers that funded this order, with how much of each it draws. Present on the order detail read for an order funded at a Conduit funding address; omitted on the list read and on an order that names its own source.
