card	See Card Schema. Note that this field will be removed and replaced with a `card_token` field in Sandbox on January 4 and in Production on February 8, 2023. Please refer to this page for more information.
amount	Authorization amount of the transaction (in cents), including any acquirer fees. This may change over time, and will represent the settled amount once the transaction is settled.
authorization_amount	Authorization amount (in cents) of the transaction, including any acquirer fees. This amount always represents the amount authorized for the transaction, unaffected by settlement.
merchant_amount	Analogous to the "amount" property, but will represent the amount in the transaction's local currency (smallest unit), including any acquirer fees.
merchant_authorization_amount	Analogous to the "authorization_amount" property, but will represent the amount in the transaction's local currency (smallest unit), including any acquirer fees.
merchant_currency	3-digit alphabetic ISO 4217 code for the local currency of the transaction.
acquirer_fee	Fee (in the currency's smallest unit) assessed by the merchant and paid for by the cardholder. Will be zero if no fee is assessed. Rebates may be transmitted as a negative value to indicate credited fees.
created	Date and time when the transaction first occurred.
events	A list of all events that have modified this transaction.
funding	A list of objects that describe how this transaction was funded, with the `amount` represented in the currency's smallest unit, including any acquirer fees. A reference to the funding source for the card that made this transaction may appear here and the `token` will match the `token` for the funding source in the `card` field. Note that this field will be removed in Sandbox on January 4 and in Production on February 8, 2023. Please refer to this page for more information.
merchant	See Merchant Schema definition below.
network	Card network of the authorization. Can be `INTERLINK`, `MAESTRO`, `MASTERCARD`, `VISA`, or `UNKNOWN`.
result	`APPROVED` or decline reason. See below for full enumeration.
settled_amount	Amount (in cents) of the transaction that has been settled, including any acquirer fees. This may change over time.
status	`PENDING`, `VOIDED`, `SETTLING`, `SETTLED`, `BOUNCED`, `DECLINED`. Note that `BOUNCED` and `SETTLING` will be removed, and `EXPIRED` will be added, in Sandbox on January 4 and in Production on February 8, 2023. Please refer to this page for more information.
token	Globally unique identifier for the transaction.
authorization_code	A fixed-width 6-digit numeric identifier that can be used to identify a transaction with networks.
cardholder_authentication	See Cardholder Authentication Schema definition below.
acquirer_reference_number	Unique identifier assigned to a transaction by the acquirer that can be used in dispute and chargeback filing. This is only populated once a transaction has been cleared, and is not available for all transactions. A single transaction can have multiple ARNs if the merchant sends multiple clearings. These are most commonly seen in the case of e-commerce (e.g., where a merchant clears purchases each time goods within a larger order are shipped) and travel (e.g., where an airline sends a unique clearing record per passenger per flight segment). Known cases where ARN will not be present are: automated fuel dispenser (AFD) transactions, single message transactions, and authorizations that are never cleared.

Event Schema

{
  "amount": Integer,
  "created": String,
  "result": Enum,
  "type": Enum,
  "token": String
}

A single card transaction may include multiple events that affect the transaction state and lifecycle.


amount	Amount of the transaction event, including any acquirer fees. Debits (event types `AUTHORIZATION_ADVICE` and `CLEARING` will appear as positive amounts and credits (event types `VOID` and `RETURN`) will appear as negative amounts. Event type `AUTHORIZATION` can be either a debit or a credit depending on the authorization type (e.g., purchase authorization vs. refund authorization).
created	Date and time this event entered the system.
result	`APPROVED` or decline reason. See below for full enumeration.
type	`AUTHORIZATION`, `AUTHORIZATION_ADVICE`, `CLEARING`, `VOID`, `RETURN`. Note that a few changes will be applied to the event type enums in Sandbox on January 4 and in Production on February 8, 2023. The following types will be added: `FINANCIAL_AUTHORIZATION`, `CREDIT_AUTHORIZATION`, `FINANCIAL_CREDIT_AUTHORIZATION`, `AUTHORIZATION_REVERSAL`, `AUTHORIZATION_EXPIRY`, `RETURN_REVERSAL`, `BALANCE_INQUIRY`, and `CREDIT_AUTHORIZATION_ADVICE`. The following type will be removed: `VOID`. Please refer to this page for more information.
token	Globally unique identifier for the event.

Merchant Schema

{
  "acceptor_id": String,
  "city": String,
  "country": String,
  "descriptor": String,
  "mcc": String,
  "state": String
}


acceptor_id	Identifier for the payment card acceptor.
city	City of card acceptor.
country	Country of card acceptor.
descriptor	Short description of card acceptor.
mcc	Merchant category code.
state	Geographic state of card acceptor.

Cardholder Authentication Schema

Lithic provides metadata on authentication attempts. These fields can be used to determine if cardholder authentication was performed prior to the authorization being submitted by the merchant. Cardholder authentication could happen via:

3-D Secure programs, such as Mastercard Secure Code or Identity Check
Digital Secure Remote Payments (DSRP) tokenized payments via Apple Pay wallets

If the cardholder is authenticated or the merchant attempts authentication and the issuer declines to verify, liability shift may apply. If it does, the merchant no longer has liability for the transaction and it cannot be charged back for fraud.

{
  "verification_attempted": Enum,
  "verification_result": Enum,
  "liability_shift": Enum,
  "3ds_version": Enum,
  "acquirer_exemption": Enum
}


`verification_attempted`	- `NONE`: Cardholder verification was not attempted. Authentication was performed via a frictionless flow, not attempted, or via standin risk-based authentication (RBA) - `OTHER`: An undefined method, such as a previously challenged recurring transaction, was used to verify the cardholder
`verification_result`	- `SUCCESS`: Authentication Verification Successful - `FRICTIONLESS`: Attempts Processing Performed; Not Authenticated/Verified, but merchant attempted authentication/verification is provided - `NOT_ATTEMPTED`: A 3DS attempt was not made for this transaction.
`liability_shift`	- `NONE`: Liability has not shifted to the issuer (i.e. the merchant is liable) - `3DS_AUTHENTICATED`: Fully authenticated (possibly recurring) transaction. Liability shift applies - `TOKEN_AUTHENTICATED`: Tokenized Payment with validated cryptography, possibly recurring, liability shift applies
`3ds_version`	3DS Protocol Version. Note that this field may appear as `three_ds_version` in some of Lithic's client libraries. - `1`: 3DS V1 was used. - `2`: 3DS V2 (EMV) was used. - `null`: No 3DS was used.
`acquirer_exemption`	Will always be `NONE`, reserved for future use. - `NONE`: No exemption applied
