```

- Mailer

```
const mailer = new IKAPI.IKMailer(LMCoreGlobals.SESSender, LMCoreGlobals.SESRegion);
```

- Process

```
export const main = async () => {
  const interval = (Docket.Globals.ExtractorPollerInterval * 1000);
  console.debug('Using interval of', interval);
  //init authorization
  await (new Docket.Core({},  Docket.Globals.AccessLevel.ANY)).authenticate(async (core) => {
    await (new IKAPI.IKProcess(Docket.Globals.API_Config, interval)).execute( async (process) => {
      await pull(core);
    });
  });
};
```

- Event Process (Queue/SQS)

```
//Main handler
export const handler = async (event, context) => {
  //Start event processor, if any event failed, execution will stop!
  await (new IKAPI.IKEventProcessor(event, context, Docket.Globals.API_Config)).processEvent( async (transaction, recordContent) => {
    //init authorization
    return await (new Docket.Core(transaction,  Docket.Globals.AccessLevel.ANY)).authenticate(async (core) => {
      core.queue.publishOnTopic(event, Docket.Globals.SNSTopic_ExtractorNotification);
      return IKAPI.IKSuccessResponse();
    });
  });
};
```

- Transaction

```
//Main handler
export const handler = async (event, context) => {
  //Start event processor, if any event failed, execution will stop!
  await (new IKAPI.IKTransaction(event, context, Docket.Globals.API_Config)).execute( async (transaction) => {
    //init authorization
    return await (new Docket.Core(transaction,  Docket.Globals.AccessLevel.ANY)).authenticate(async (core) => {
      const queue = event.queue;
      //Get from specified queue
      if (!queue) throw new Error(`Empty queue URL! - ${queue}`);
      //Success :)
      return IKAPI.IKSuccessResponse();
    });
  });
};
```

- Dynamo Streams

```
//Main handler
export const handler = async (event, context) => {
  //Start event processor, if any event failed, execution will stop!
  await (new IKAPI.IKDynamoStream(event, context, Docket.Globals.API_Config)).processEvent( async (transaction, recordContent) => {
    //Check if is deletion
    if (!_isDynamoDeletion(recordContent)) return (new IKAPI.IKSuccessNoContentResponse());
    //init authorization
    return await (new Docket.Core(transaction,  Docket.Globals.AccessLevel.ANY)).authenticate(async (core) => {
      return IKAPI.IKSuccessResponse();
    });
  });
