Use Custom JSAPI in mini program

For customizing JSAPI, there are two situations: customizing the existing JSAPI and adding a new JSAPI. Their usages may be a little different.

For customizing the existing JSAPI, the name of the JSAPI is already known in the Mini Program Framework, so mini program developers can call my.apiName directly to use the existing API.

But for adding a new JSAPI, the name of the JSAPI is only known on the native side (Android or iOS), and the Mini Program Framework can not recognize the call if developers call my.apiName because the apiName is unknown. So for these APIs, developers should use the following method to call the JSAPI.

my.call(apiName, params, callback);

For the detailed input parameters, refer to the following table.

Although you can use my.call to call JSAPI, try to avoid using this method because the mini program may be abnormal in other apps if they do not implement these APIs.
