Serverless project to send and receive media files for image recognition by AWS Rekognition

Objective

Set up a Serverless project that can be connected to a Twilio Whatsapp account/sandbox to send and receive media files for image recognition by AWS Rekognition via AWS Lambda

Pre-requisites

To have serverless setup , refer to 'Pre-requisites after cloning project' listed in this link

Note: You can choose to skip steps which ask to set up Twilio Account SID , Auth Token, 'from' and 'to' numbers since these are only needed to send outbound messages from Twilio to recipients. In our project, we are initiating a message from our WhatsApp account to Twilio whatsapp sandbox/business account and expecting a response back on the same number.

How to link your phone to the Twilio

However, you still need to have a way for Twilio to be able to accept messages from your phone. To do this, follow instructions from official Twilio website to create an account and link your phone to the Twilio sandbox number they assign to your account using the join <secret-phrase> first message to the sandbox.

Once done, to have Twilio interact with your AWS serverless stack, you need to have a webhook linked to your Twilio account . Refer to 'Configure your Webhook URL' part of this link The webhook link to use is the one that shows under 'endpoints' once you have deployed your serverless stack using command serverless deploy from your project root folder after you have completed pre-requisites.

Workflow overview:

1. User sends an image in form of screenshot or jpeg/png file to the Twilio sandbox number.
2. The Twilio account receives the media file and makes a call to the webhook.
3. The webhook is an HTTP end point for AWS lambda , which sends the image to AWS Rekognition.
4. Rekognition responds back with the celebrities identified.
