API Doc - Checkout Intent Routes - Get Status

AllScale Open API Version: v3 Last updated: 2026-05-14 Base Path: /v1/checkout_intents

Overview

The Checkout Intent Status API allows merchants to query the current status of a checkout intent.

This API is used to:

• Retrieve the checkout intent status by checkout_intent_id

• Poll status after creating a checkout intent and redirecting users to hosted checkout

---

Important Design Notes

• All enum values are represented as integers in API requests and responses

• API consumers must always send and receive integer values

• This endpoint returns only the status integer (in payload)

---

Authentication

All requests must include the following headers:

Header	Description
X-API-Key	API key
X-Timestamp	Unix timestamp (seconds)
X-Nonce	Unique request identifier
X-Signature	HMAC signature

Notes

• X-Nonce must be unique per request

• X-Timestamp must be within allowed time window

• Signature must be generated using raw request body bytes

• Requests are protected against replay attacks

---

40001	Rate limit exceeded

---

Notes

• This endpoint enforces permission checks: the checkout intent must belong to the authenticated store/business context.

• Always log request_id for debugging.

• Since payload is an int, do not expect payload.status or other nested fields.
