Poll UserOperation status

Authorizations

x-juno-jwt
string
header
required

JWT issued by Dynamic Labs or Privy. Sent in the x-juno-jwt header on every authenticated request.

Headers

x-juno-orgid
string | null

Tenant org ID for multi-tenant auth

x-sumvin-token
string | null
x-sumvin-pat
string | null
x-juno-jwt
string | null
X-Timestamp-Format
string

Controls how timestamp fields are serialized in JSON response bodies.

Default (header omitted or any other value): epoch milliseconds as integers. iso8601: UTC ISO 8601 strings of the form YYYY-MM-DDTHH:MM:SSZ.

Example: with X-Timestamp-Format: iso8601, the field value 1704067200000 becomes "2024-01-01T00:00:00Z".

Affected fields (recursively, in dicts and arrays): any field whose name ends in _at, plus the literal field names timestamp, period_start, and period_end. All other fields are passed through unchanged.

Only iso8601 is recognized. Any other value (or omitting the header) yields the default epoch-ms representation; the server does not reject unknown values, so this is documented as an example rather than an enum to keep generated clients permissive.

Example:

"iso8601"

Path Parameters

user_op_hash
string
required

Response

UserOperation status retrieved.

HAL navigation links. Includes a receipt link to the underlying transaction receipt when txn_hash is populated.

user_op_hash
string
required

The UserOperation hash that was polled.

status
string
required

Current lifecycle status. One of: not_found, not_submitted, queued, submitted, included, rejected, failed. included and failed are on-chain terminal states; rejected is a pre-submission terminal state with no transaction hash.

txn_hash
string | null

On-chain transaction hash of the bundle that contained this UserOperation. Present once the operation reaches included or failed. Absent for rejected operations because they never reached the chain.

block_number
integer | null

Block number containing the bundle transaction, once on-chain.

gas_used
integer | null

Gas units consumed by this UserOperation, populated after inclusion.

actual_gas_cost_wei
integer | null

Total gas cost in wei attributed to this UserOperation, populated after inclusion. Sumvin's paymaster covers this — the user is not charged.

success
boolean | null

True when the UserOperation succeeded on-chain, false when it reverted, and null while the operation is still pending.
