        Middleware (Python) to automatically log API calls from AWS Lambda functions
        and sends to [Moesif](https://www.moesif.com) for API analytics and log analysis. 
        
        Designed for APIs that are hosted on AWS Lambda using Amazon API Gateway as a trigger.
        
        This middleware expects the
        [Lambda proxy integration type.](https://docs.aws.amazon.com/apigateway/latest/developerguide/api-gateway-set-up-simple-proxy.html#api-gateway-set-up-lambda-proxy-integration-on-proxy-resource)
        If you're using AWS Lambda with API Gateway, you are most likely using the proxy integration type.
        
        ## How to install
        
        ```shell
        pip install moesif_aws_lambda
        ```
        
        ## How to use
        
        The following shows how import the module and use:
        
        ### 1. Import the module:
        
        ```python
        from moesif_aws_lambda.middleware import MoesifLogger
        import os
        
        # Moesif Application Id
        os.environ["MOESIF_APPLICATION_ID"] = "Your Moesif Application Id"
        
        def identify_user(event, context):
            return 'my_user_id'
        
        def identify_company(event, context):
            return 'my_company_id'
        
        def get_api_version(event, context):
            return '1.0.0'
        
        def get_session_token(event, context):
            return '23jdf0owekfmcn4u3qypxg09w4d8ayrcdx8nu2ng]s98y18cx98q3yhwmnhcfx43f'
        
        def get_metadata(event, context):
            return { 'foo' : 'aws lambda', 'bar' : 'aws lambda metadata', }
        
        def mask_event(eventmodel):
            return eventmodel
        
        def should_skip(event, context):
            return "/" in event['path']
        
        moesif_options = {
            'GET_METADATA': get_metadata,
            'IDENTIFY_USER': identify_user,
            'IDENTIFY_COMPANY': identify_company,
            'GET_SESSION_TOKEN': get_session_token,
            'GET_API_VERSION': get_api_version,
            'MASK_EVENT_MODEL': mask_event,
            'SKIP': should_skip,
            'LOG_BODY': True,
            'DEBUG': True
        }
        
        @MoesifLogger(moesif_options)
        def lambda_handler(event, context):
            return {
                'statusCode': 200,
                'isBase64Encoded': False,
                'body': {
                    'msg': 'Hello from Lambda!'
                },
                'headers': {
                    'Content-Type': 'application/json'
                }
            }
        ```
        
        ### 2. Enter Moesif Application Id
        Your Moesif Application Id can be found in the [_Moesif Portal_](https://www.moesif.com/).
        After signing up for a Moesif account, your Moesif Application Id will be displayed during the onboarding steps. 
        
        You can always find your Moesif Application Id at any time by logging 
        into the [_Moesif Portal_](https://www.moesif.com/), click on the top right menu,
         and then clicking _Installation_.

        - `lambda_function.py` sample AWS Lambda function using the middleware
        
        ## Configuration options
        
        #### __`IDENTIFY_USER`__
        
        Type: `(event, context) => String`
        
        `IDENTIFY_USER` is a function that takes AWS lambda `event` and `context` objects as arguments
        and returns a user_id. This enables Moesif to attribute API requests to individual unique users
        so you can understand who calling your API. This can be used simultaneously with `IDENTIFY_COMPANY`
        to track both individual customers and the companies their a part of.
        
        
        ```python
        def identify_user(event, context):
          # your code here, must return a string
          return event["requestContext"]["identity"]["cognitoIdentityId"]
        ```
        
        #### __`IDENTIFY_COMPANY`__
        
        Type: `(event, context) => String`
        
        `IDENTIFY_COMPANY` is a function that takes AWS lambda `event` and `context` objects as arguments
        and returns a company_id. If your business is B2B, this enables Moesif to attribute 
        API requests to specific companies or organizations so you can understand which accounts are 
        calling your API. This can be used simultaneously with `IDENTIFY_USER` to track both 
        individual customers and the companies their a part of. 
        
        
        ```python
        def identify_company(event, context):
          # your code here, must return a string
          return 'my_company_id'
        }
        ```
        
        #### __`GET_SESSION_TOKEN`__
        
        Type: `(event, context) => String`
        
        `GET_SESSION_TOKEN` a function that takes AWS lambda `event` and `context` objects as arguments and returns a
        session token (i.e. such as an API key).
        
        
        ```python
        def get_session_token(event, context):
            # your code here, must return a string.
            return '23jdf0owekfmcn4u3qypxg09w4d8ayrcdx8nu2ng]s98y18cx98q3yhwmnhcfx43f'
        ```
        
        #### __`GET_API_VERSION`__
        
        Type: `(event, context) => String`
        
        `GET_API_VERSION` is a function that takes AWS lambda `event` and `context` objects as arguments and
        returns a string to tag requests with a specific version of your API.
        
        
        ```python
        def get_api_version(event, context):
          # your code here. must return a string.
          return '1.0.0'
        ```
        
        #### __`GET_METADATA`__
        
        Type: `(event, context) => String`
        
        `GET_METADATA` is a function that AWS lambda `event` and `context` objects as arguments and returns an object that allows you to add custom metadata that will be associated with the request. The metadata must be a simple python object that can be converted to JSON. For example, you may want to save a function_name, a trace_id, or request_context with the request.
        
        
        ```python
        def get_metadata(event, context):
          # your code here:
          return {
                'trace_id': context.aws_request_id,
                'function_name': context.function_name,
                'request_context': event['requestContext']
            }
        ```
        
        #### __`SKIP`__
        
        Type: `(event, context) => Boolean`
        
        `SKIP` is a function that takes AWS lambda `event` and `context` objects as arguments and returns true
        if the event should be skipped (i.e. not logged)
        <br/>_The default is shown below and skips requests to the root path "/"._
        
        
        ```python
        def should_skip(event, context):
            # your code here. must return a boolean.
            return "/" in event['path']
        ```
        
        #### __`MASK_EVENT_MODEL`__
        
        Type: `MoesifEventModel => MoesifEventModel`
        
        `MASK_EVENT_MODEL` is a function that takes the final Moesif event model (rather than the AWS lambda event/context objects) as an argument before being sent to Moesif. With maskContent, you can make modifications to headers or body such as removing certain header or body fields.
        
        ```python
        def mask_event(eventmodel):
          # remove any field that you don't want to be sent to Moesif.
          return eventmodel
         ```
        
        #### __`DEBUG`__
        
        Type: `Boolean`
        
        Set to true to print debug logs if you're having integegration issues. 
        
        #### __`LOG_BODY`__
        
        Type: `Boolean`
        
        `LOG_BODY` is default to true, set to false to remove logging request and response body to Moesif.
