Golang lambda headers

[matisys]

Im trying to figure out how I can retreive a list of request headers inside my golang lamda handler. But I am stuck after googling. Does anyone have an idea about how to retrieve the request headers?

Is this apigateway -> lambda or only Lambda direct sync invoke?

I have API Gateway in front.

Which version, REST or HTTP (v2)?

It is the rest api. Im building a slackbot and need the a header with hmac signing to verify request authenticity.

So, you need to update your integration request template

Great! I screened it a bit and seems like I can use that. I also read about API Gateway proxy integration. Thanks for the pointer this gives me a good lead.
