POST
POST /payment/purchase authorizes and captures funds in a single round-trip. Use it when you can fulfill the order immediately — digital goods, SaaS subscriptions, or in-stock retail. For physical goods that ship later, consider Authorize + Capture to hold funds until fulfillment without settling early. The full request and response schemas — every card/shopper/amount field, the status values, and refusalCode/actionRequired/token detail — are documented in the parameters and response panels above (generated from the API spec).
The response’s id is the Therius payment UUID — store it, it’s the handle for a later Refund or Cancel or Refund call. paymentCode (e.g. "PC-1234567890") is a separate reference for reconciliation, support and Inquiry — it is not accepted for refund/cancel.

Examples

Charge a card

Declined response
amount.value is always in minor units. 1999 = $19.99 for USD (exponent 2). 5000 = ¥5000 for JPY (exponent 0). Always use the exponent field to determine the decimal position.
If status is "pending_3ds", redirect the cardholder to actionRequired.url to complete the 3D Secure challenge. Once they finish, call POST /payment/resume with the sessionId from the pending_3ds response to continue. If you use the Therius JS SDK, call sdk.handleAction(result.actionRequired) — it handles the redirect and resume automatically.

Authorizations

Authorization
string
header
required

Your secret API key: Bearer prv_production_xxx (production) or Bearer prv_sandbox_xxx (sandbox).

Headers

Idempotency-Key
string<uuid>

A UUID you generate per operation. Required in production. Retrying with the same key returns the original response.

Body

application/json
merchantCode
string
required

Your merchant account identifier. Validated against the Bearer key's merchant; required if the key maps to more than one merchant account.

orderCode
string
required

Your internal order reference. Must be unique per merchant — use it to correlate Therius payments with your own records.

amount
object
required
card
Raw card (PCI DSS) · object

Card input for one-off payments: exactly one instrument (cardData / nonceData / tokenData) plus optional stored-credential and installment modifiers.

apm
object

Alternative payment method data — use instead of card for APMs such as Pix, ACH or Boleto. Structure varies by method.

paymentMethod
string

Payment method code. Omit for card payments; for APMs pass the code, e.g. pix, ach, boleto.

shopper
object

Shopper information. Required when tokenizing a card (card.<instrument>.tokenize: true).

webhookUrl
string

Per-payment webhook URL override (HTTPS only). Therius posts the final payment status here when it changes asynchronously.

connectionCode
string

Pin this payment to a specific gateway connection. Omit to use your routing rules.

ipAddress
string

Cardholder's IP address, passed to fraud scoring when available.

metadata
object

Arbitrary string key/value pairs, echoed back in webhook payloads.

Response

200 - application/json

Payment processed

id
string<uuid>

The Therius payment id. Returned by POST /payment/authorization and POST /payment/purchase; use it as the {id} path segment for capture, refund, cancel and cancel_or_refund.

Example:

"9f8b2c1e-4d5a-6b7c-8d9e-0f1a2b3c4d5e"

status
enum<string>

captured - funds settled; authorized - funds reserved, call capture to settle; declined - issuer declined, see refusalCode; pending_3ds - a 3DS challenge is required, see actionRequired; pending_action - an external action (redirect, voucher) is required, see actionRequired; failed - processing error unrelated to the issuer; cancelled - authorization voided; refunded - captured funds returned.

Available options:
captured,
authorized,
declined,
pending_3ds,
pending_action,
failed,
cancelled,
refunded
paymentCode
string

Therius receipt ID, for reconciliation, support and Inquiry. NOT the handle for capture/refund/cancel — use id for that.

Example:

"PC-1234567890"

orderCode
string

Your orderCode, echoed back.

merchantCode
string

Your merchantCode, echoed back.

autorizationCode
string

Issuer authorization code on an approved payment. The field name is misspelled on the wire (no h) - this is intentional and stable.

connectionCode
string

Code of the gateway connection that processed the payment.

connectionName
string

Display name of the gateway connection that processed the payment.

Card details from the response: masked PAN, brand, type, and the network transaction/reference IDs to cite on future MIT charges.

apm

Alternative-payment-method details (redirect URL, QR code, barcode) when paymentMethod is an APM.

token
object

Present when the card was tokenized (tokenize: true).

actionRequired
object

Present when status is pending_3ds or pending_action. Describes what the cardholder must do next — with the Therius JS SDK, pass the whole object to sdk.handleAction().

refusalCode
object

Present when status is declined. See the Declined Payments concept page for the full code table and how to react to each recoveryAction.
