How to setup a developer account
As a developer you always want your environment to test and play with different features. This is normally quite a mission but with WeChat it is easy.
This can be created by going to English Sandbox. Please note the mobile number needs to be in the format +27723123456
If you are not getting an APP_ID or APP_SECRET please use Chinese Sandbox instead by clicking the green login button and then scanning the QR code with your wechat app.
