Without this crucial information about delay on 22:08 I was unable to attach my authorizer to a method.

Great, to the point video, exactly what I wanted. Thank you. Does anyone know if a request header can be updated in the custom authorizer before the sending the request to the service fronted by the API gateway?

[Disproportionableness]

The is exactly the foundation I needed to get started with gateway auth. Thank you thank you thank you thank you thank you.

Very helpful video. I had it done through cloudformation template and it worked. Keep up the good work.

This was really easy to follow! Thank you!

2:37 I think they make you return a relatively complex policy document (as a opposed to a simple "Allow"/"Deny") so that you can Allow/Deny for an array of resource ARNs.

[christopher]

Excellent video! Keep up the good work.

[VishalRaoOnYouTube]

Oh YEAH! Gonna watch this tonight! Thanks man!

[vijayvavilapalli]

We expect more videos from you.. like this thankyou

[pradeepmca]

Were exactly is policy document configured? How is the policy response format is validated? Based on Policy response from authorize, how does API gateway interpret to have the intelligence to allow or deny a request? These clarity on these to get full understanding of nicely explained video.

[krishind]

This is fantastic. Would love to see, how and where authorization token is generated. Do you have a video on that?

[coderite]

Oh My this video is a life saver
Thanks so much for this

[MS-ewru]

thanks for the great tutorial, really helpful! one thing I still can't get, how can we pass actual tokens to this lambda authorizer (as in instead of"abc123" in this example)?
