¶ Request parameters
| Name | Type | Required | Default value | Description | Sample value |
|---|---|---|---|---|---|
| type | string | Yes | - | QR code type. Currently supports three types: - MOBILE_APP: Scan the QR code with a self-built mobile APP- WECHAT_MINIPROGRAM: Scan the QR code with a WeChat applet- WECHAT_OFFICIAL_ACCOUNT Scan the QR code with a WeChat public account | MOBILE_APP |
| extIdpConnId | string | No | - | When type is WECHAT_MINIPROGRAM or WECHAT_OFFICIAL_ACCOUNT, you can specify the identity source connection, otherwise the first corresponding identity source connection opened by the application is used by default to generate the QR code. | 62eb7ed1f04xxxxc6955b329 |
| customData | object | No | - | When type is MOBILE_APP, you can pass the user's custom data. When the user successfully scans the QR code for authorization, this data will be stored in the user's custom data. | {"school":"hust"} |
| context | object | No | - | When type is WECHAT_OFFICIAL_ACCOUNT or WECHAT_MINIPROGRAM, specify a custom pipeline context, which will be passed in the pipeline context | {"source":"utm"} |
| autoMergeQrCode | boolean | No | - | When type is WECHAT_MINIPROGRAM, whether to automatically merge the custom logo into the generated image, the default value is false. The process of merging QR codes on the server will increase the interface response speed. It is recommended to use the default value and stitch the images on the client. If you use the GenAuth SDK, you can save the manual stitching process. |
