# Generate Dynamic QR Code

> Create a dynamic PIX QR code.

Create a dynamic PIX QR code for the authenticated target account. Currency is fixed internally to BRL.

### Endpoint

`POST /v3/qr_code/generate/dynamic`

### Authentication and target

Use an account credential for its bound account, or a user credential with both `X-ISPB` and `X-Account-Number`. If an account credential sends those headers, both must be present and must match its bound account. Platform credentials are not accepted. All requests require the standard HMAC-SHA256 headers. This path also enforces the applicable active-user and PAYIN scene checks.

The curl example below uses an ACCOUNT credential bound to the operated account, so it omits X-ISPB and X-Account-Number. If X-Client-ID identifies a USER credential, add both target headers and include their exact trimmed values in the canonical header set before calculating X-Signature.

### Request body

| Field                             | Required    | Type    | Validation or default                                                                        |
| --------------------------------- | ----------- | ------- | -------------------------------------------------------------------------------------------- |
| `merchant_order_id`               | Yes         | string  | Non-empty; downstream accepts letters, digits, hyphen, and underscore.                       |
| `pix_key`                         | Yes         | string  | Required. The current handler surfaces an empty value as business code 500.                  |
| `pix_key_type`                    | No at edge  | number  | Numeric PIX-key enum; downstream validates key/type semantics.                               |
| `amount`                          | Yes         | string  | Positive decimal with at most two places.                                                    |
| `expires`                         | No          | number  | Seconds; 0 defaults to 7200. No verified public min/max is implemented here.                 |
| `memo`, `city`                    | No          | string  | Passed downstream.                                                                           |
| `payer_document_id`, `payer_name` | Conditional | string  | Supply both or neither. Document length must be 11 or 14.                                    |
| `payer_verify`                    | No          | boolean | Defaults false. Payer data is forwarded only when true and both payer fields are present.    |
| `reuseable`                       | No          | string  | Present in the contract but not propagated by the current service mapper; do not rely on it. |

### Success data

`payload_base64`, `qr_code_id`, and `merchant_order_id`.

### Behavior and validation

Payer data may be omitted, but a partial payer pair is rejected. Creation is synchronous from this API's perspective. The only implementation-backed expiry behavior is the submitted `expires` value or its 7200-second default.

### Errors

Every call can fail for missing or invalid signature headers, an expired timestamp, nonce replay, an invalid body hash or signature, insufficient permission, or a downstream service error. Endpoint-specific errors include:

* Business code `4000` for a missing merchant order or incomplete payer pair.
* `4002` for an invalid amount or payer-document length.
* Current business code `500` for a missing `pix_key`.
* `4003008` when account context is unavailable, plus mapped downstream validation/processing errors.
