1. Configuring the authorization callback page URL
For security reasons, the Alipay web-based authorization service verifies whether the redirect_uri specified in the web-based authorization page URL is consistent with that set on the Alipay platform. To configure the redirect_uri on the Alipay open platform, complete the following steps:
- Login to Developer center of Alipay Open Platform
- Create an application if you don’t have one yet.
- Open the app detail page. https://openhome.alipay.com/platform/detailApp.htm?appId=my_awesome_app_id
- Set the callback URL as showed in the figure below.
