Result process logic

In the response, the result.resultStatus field indicates the result of processing a request. The following table describes each result status:

Result status	Description
S	The request to create a QR code is successful, which means the QR code value and image are generated and returned to the merchant. Note: For the QR code generated with the same appId, appQrCodePage, appQrCodePage, and appQrCodeParams and reach an `S` status, the same QR code value and image are returned. For more information, see Idempotency. The corresponding result.resultCode is `SUCCESS` and the result.resultMessage is `Success`.
U	The status of the request to create a QR code is unknown. The corresponding result.resultCode is `UNKNOWN_EXCEPTION` and result.resultMessage is "An API calling is failed, which is caused by unknown reasons.". For details, see the Common error codes section.
F	The request to create a QR code is failed. The corresponding result.resultCode and result.resultMessage are various based on different situations. For details, see the following Error codes section.

Error codes

Error codes are usually classified into the following categories:

Common error codes are common for all mini program OpenAPIs in V2.
API-specific error codes: The current OpenAPI does not have its dedicated error codes.

Samples

The data flow of creating a QR code is illustrated as below:

The merchant server or the ISV server calls this API to request Mini Program Platform to create a QR code.
Mini Program Platform processes the request and returns the generated QR code value and image to the merchant server or the ISV server.
