After the external Vault owner executes the returned transaction for an execute_safe_transaction action, submit its transactionHash. Submitting the hash does not by itself activate the policy. Stableyard verifies the transaction receipt and the policy on chain before activation. Idempotency-Key is required.

Authorizations

Authorization

string

header

required

HTTP Basic auth. Username is the Stableyard app ID. Password is the app secret. The optional Stableyard-Version request header must match the environment pin.

Headers

Idempotency-Key

string

required

Retry key. Reuse a key only with the identical request; different input returns a conflict.

Example:

"request-key-001"

Stableyard-Version

enum<string>

Optional contract-version assertion. Omit it to use the app environment's pinned version. A different supported version is accepted only after that environment is explicitly migrated.

Available options:

2026-09-09

Path Parameters

accountId

string

required

Canonical account id returned by the Accounts API.

Example:

"acct_123"

actionId

string

required

Body

application/json

transactionHash

string

required

Pattern: ^0x[a-fA-F0-9]{64}$

Example:

"0xaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"

Response

Vault action

string

required

Example:

"vault_action_123"

vaultId

string

required

Example:

"vault_123"

type

enum<string>

required

Available options:

sign_policy,

approve_managed_policy,

install_policy,

auto_supply_yield,

execute_payment

status

enum<string>

required

Available options:

pending,

required

updatedAt

string<date-time>

required

policyId

string | null

Example:

"vault_policy_123"

nextAction

object | null

Public wallet, signature, email approval, or wait instruction. Treat the action type as the discriminator and never modify transaction calldata. execute_safe_transaction is an on-chain transaction the Vault owner must execute; it includes a completion request descriptor for submitting the mined transaction hash.

failureCode

string | null

expiresAt

string<date-time> | null
