Web SDK Chrome Extension API

Initialize the SDK

Interface Description

To prevent a large number of invalid users, it is recommended to use a unique and consistent user_str during initialization. You can generate user_str based on the browser fingerprint.

Example Call

if (window.MTpushInterfaceExtension) { window.MTpushInterfaceExtension.initSdk({ appkey: '', user_str: '', }); }

              
              if (window.MTpushInterfaceExtension) {
  window.MTpushInterfaceExtension.initSdk({
    appkey: '',
    user_str: '',
  });
}

Parameter Description

interface InitType { appkey: string; // The appkey of the application registered by the developer on the EngageLab platform. Required. user_str: string; // Unique user identifier. Required. }

              
              interface InitType {

Get Results

chrome.runtime.onMessage.addListener((message) => { switch (message.type) { // SDK initialization succeeded case 'MTPUSH_INIT_SDK_SUCCESS': console.log(message.data); break; // SDK initialization failed case 'MTPUSH_INIT_SDK_FAIL': console.log(message.data); break; } });

              
              chrome.runtime.onMessage.addListener((message) => {
  switch (message.type) {
    // SDK initialization succeeded
    case 'MTPUSH_INIT_SDK_SUCCESS':
      console.log(message.data);
      break;

    // SDK initialization failed
    case 'MTPUSH_INIT_SDK_FAIL':
      console.log(message.data);
      break;
  }
});

The structure of message.data is as follows:

interface MessageData { code: number; // Status code. 0 indicates success, others indicate failure. Refer to error codes. message: string; // Result description. content: string; // Returns failure information when registration fails with error code 1003. }

              
              interface MessageData {
  code: number; // Status code. 0 indicates success, others indicate failure. Refer to error codes.
  message: string; // Result description.
  content: string; // Returns failure information when registration fails with error code 1003.
}

If the integration of the extension fails due to an expired free trial or paid plan for the application, the initialization process will be retried when a new page is opened or an existing page is refreshed after 4 hours.

Get RegistrationID

Interface Description

There's no need to manually call an API to get the regid. After the SDK initializes successfully, you can obtain the regid from the information returned by the MTPUSH_GET_MT_INIT_INFO event.

Example Call

chrome.runtime.onMessage.addListener((message) => { switch (message.type) { case 'MTPUSH_GET_MT_INIT_INFO': console.log(message.data.regid); break; } });

              
              chrome.runtime.onMessage.addListener((message) => {
  switch (message.type) {
    case 'MTPUSH_GET_MT_INIT_INFO':
      console.log(message.data.regid);
      break;
  }
});

              // Call after the SDK initializes successfully
window.MTpushInterfaceExtension.getPushAuthority();

window.MTpushInterfaceExtension.setTagsAlias({ tags: ["test1", "test2"], alias: "aliass" });

              
              window.MTpushInterfaceExtension.setTagsAlias({ tags: ["test1", "test2"], alias: "aliass" });
