Decode QR

Decodes a QR code string and returns a decode response with the fields needed for **getQuotation** and **executePayout**. **Flow:** 1. Authenticates the request and verifies `customer_id` exists under your account (registered via `registerCustomer`). 2. Derives routing hints from the QR, then **parses and enriches the QR string through country-appropriate local payment providers.** 3. Validates supported country/currency for the QR against your account configuration (`INVALID_COUNTRY_CODE`, `INVALID_CURRENCY` when not allowed). 4. Computes `is_dynamic` and `is_business` from provider QR metadata when available, otherwise from fallback rules on the decoded data. 5. Creates a **PENDING** transaction and returns `tx_id`. **Authentication:** - **REQUIRED**: Basic Auth: `Authorization: Basic base64(client_id:client_secret)`. - Body-based `client_id` / `client_secret` is deprecated and **not supported**. **Request body** - `qr_string` (string, **required**) - `customer_id` (string, **required**) - be provided in request body, - not contain `/`, - exist under your account's `registered_customers`, and - match the `customer_id` bound to the transaction. - `partner_transaction_id` (string, optional) - `payment_currency` (string, optional): ISO 4217. For **Indonesia**, required when currency cannot be resolved from the QR; otherwise **400** with `payment_currency is required for Indonesia QR decode (or provide a QR that includes currency)`. - `wallet_identifier` (string, optional): stored on the transaction when provided. **Response (200 JSON)** — curated public fields only (no internal `_`\-prefixed blobs). - `is_dynamic`, `is_business`, `amount`, `merchant`, `country`, `tx_id`, `currency`, `partner_transaction_id` (empty string if not sent) - `missing_fields` (optional): machine-readable schemas for required data not yet satisfied - `suggested_values` (optional): hints keyed by field paths for UI prefill - `sender` / `recipient` (optional): grouped echoes when meaningful after decode - When `amount` > **0** and pricing succeeds: `amount_usd`, `fee`, `percentage_fee`, `fixed_fee` (USD values rounded to **2** decimal places in JSON). `exchange_rate` is **not** returned here (use **getQuotation** / **executePayout** for rate details). **Bank terminology:** Prefer grouped `recipient.bank_no`; legacy flat keys are mapped internally. **Currency precision:** Decimal amounts follow the currency table in this collection overview. **Payout flow:** **decodeQr** → **getQuotation** (recommended when locking fees/amount) → **executePayout**. **Note:** Stored `qr_data` may include provider-internal fields; they are not returned on this endpoint.
