Getting Slack user email address for AWS Lex bot

Question

I am creating a bot in aws-lex and will integrate it with Slack, FB Workplace and Yammer to start with.

I need to read the Slack user email address, then validate that against our webservice to ensure the user is registered. This will return some data about the users organisation that I need for further execution in lex.

I have no idea how to pass/extract the Slack user email (the one that is engaging in conversation with my Bot).

Any ideas?? Examples please! New to bot dev.

One hint specific to your problem: You can get the email from a user with this API method: users.info — Erik Kalkoken

At least for slack you could do:

Under requestAttributes (from event) you can check the presence of x-amz-lex:channel-type. The value will be Slack if the user comes from slack.

You can then extract the user slack id from the event that is submitted to your lambda under the key userId

With that id, go to Slack API and call the method users.info. Now you can get the user email from the response.
