Secure your API Gateway with Amazon Cognito User Pools | Step by Step AWS Tutorial

Amazon Cognito is a powerful AWS service that enables user logins and federated identities. Cognito can be leveraged as an authentication and authorization mechanism for your APIs built through AWS API Gateway. In this video, I show you how to create an Amazon Cognito User Pool and attach it as an authentication handler to your API Gateway REST api.

love that you don’t scrub the mistakes out of your videos. thats how real life goes, and i feel it’s important for those new to the industry to see their seniors working through mistakes. great video.

[@BeABetterDev]

Mistakes happen in real life! Its important to see the whole process :D

[@mogomotsiseiphemo1681]

Great video! At this point 23:45, to avoid having to manually change from "code" to "token" in the redirect, you just have to select "Implicit grant" only when setting the OAuth 2.0 Auth Flow at 7:20!

[@shishamo-san]

Thank you:)

[@manavkhandurie3591]

Thank you so much

[@TheTruthNotControl]

This was a brilliant tutorial. I have watched many videos from various people on youtube, udemy and you name it, I have been on the sites. Yet you talked in such a, lets get this done and ill show you manner instead of lots of talking but spoke about a process when needed was just great. I learned alot from this, thank you. I subbed and liked this video.

[@BeABetterDev]

Thank you so much for your kind words Daryl. I always try to present my content in a relatable way that synthesizes the complexity of a topic into an easy to understand presentation. I'm glad you found this useful - and thank you for the kind words! Daniel

[@Ryuugaminechan]

Was stuck with this for a couple of hours now. Didn't realize that you need to deploy the API after making changes. This video really helped me. Thanks!

[@BeABetterDev]

You're very welcome!

[@fatihersoy7559]

This video made me subscribe to your channel immediately. It's impressing how easy to understand from you, especially after spending hours on understanding nothing about the topic.

[@jeromeeusebius]

BeABetterDev: Thanks for putting this video together. I followed the API Gateway Lambda one and this version with Cognito. The option is Cognito is much richer and I will be exploring it with my app. It is good that the video is also an actual workthrough with details and it was easy and nice to follow and I was able to replicate the results.

[@BeABetterDev]

Glad this was helpful!

[@eugenevedensky6071]

This video along with your RDS lambda integration video is pretty much all you need to get a robust web app going super quickly. Great content. EDIT: In case you ever read this, do you have any insight how you might apply RBAC with this strategy?

[@kreeve6144]

Love this video! The only thing I've found different in my scenario is that passing the Authorization header won't work with the access token. It only works with the id token for some reason

Thanks for the great video! I'd gotten past the initial login step just fine but had no idea what to do with the tokens passed back. Got a bit of template work to do linking the Lambdas/Gateway/Cognito but it should be easy peasy thanks to your demo.

[@ppgg997]

Great explanations!! One question, on authorizer test , you used Token id but calling the api path from Postman you put in header the access token instead. Whats the difference and why each one needed in the corresponding scenario?

[@kishanlal676]

23:49 I guess you don't have to do that manually if you allow only the 'Implicit grant' when you check the 'Allowed OAuth Flows' section at 7:25 which would set the response_type to token automatically. But, this is not suggested unless you're using a Single Page App without any backend

Currently running into issues trying to adapt this to the "HTTP API" on API Gateway to use Cognito User Pools as an authorizer but stumbling on the step about JWT as a source. I'll fumble my way through it and I wanted to say that I am grateful your content getting me this far. Authorizing the new HTTP API Gateway could be another idea for content if that's something to add to your list of content ideas. Thanks for the high quality content though ^_^

[@BeABetterDev]

Hey josh, Have you tried taking a look at my video on HTTP APIs in API Gateway? I think you can possibly combine the content from this video and the one below. kzbin.info/www/bejne/g2qUp4uan9uYbaM Hope this helps. Daniel

[@JoshPeak]

@@BeABetterDev thanks for the reply. I managed to fumble my way through it with this video kzbin.info/www/bejne/pWiyeaKdisiFo6s The one you just linked me, filled in some gaps for me about logging and cloud watch. 👏 Thanks again for all of your content. I’ve smashed the like 👍 button on all the videos that I have watched (to feed the algorithm).

[@BeABetterDev]

Thanks so much Josh! I'm glad you were able to work through it and appreciate the support! Thanks again and stay safe :)

[@hbladeh]

If I understand correctly what you did is basically by writing token into the URL you switched from "Authorization code" grant to "Implicit" grant type. If you're using a URL that's outside of AWS and travels through the web use code instead and use the Token endpoint of the identity provider (in this case Cognito), to get a token in the Body, and post it as a header in the HTTP Request, not as the part of the URL itself.

Great video! Just a question - how come when you point to the URL for the API it does not redirect to the login page? or would you need to create that in your client side code in something like an "IF" statement?

You are the best bro, thanks.

[@BeABetterDev]

[@NurseDaveBSMSON]

[@FundaDuval-eb8qj]

Hi I love the pace & no fluff! I have 2 questions: 1) Can you use user pool authorizers with federated ID integration (like with AzureAD)? User will be using SSO. and 2) does this remove the need/use-case for Lambda@Edge?

[@oy_oy]

genius, brilliant

[@AhumadaMauricio]

Great video. I think there's a little change in the way the authorization token is validated in the api gateway, in order to send a request using postman make sure you send the token using the Authorization tab and selecting "Bearer " on the dropdownlist. Do not include the token on the URL as this will not be correctly authorized by api gateway.

[@markfiala3652]

Fantastic video, I really appreciate it. In my case though, I’d like to use Cognito in kind of a stateless situation, I would prefer to enter the login and password in the header ( or base64 version of it with basic authentication) instead of logging in to get it token first. Reason being I’m connecting it from the output of other web services that do something and there isn’t really the mechanism to get a temporary token. Any ideas how to do that?

Is there a way to make the cognito-authorizer only allow certain usergroups from Cognito to invoke the lambda or do I need to make own lambda authorizer?

Any chance of a refresher video using the latest version of cognito and API gateway?

[@jonathanfalcone3437]

This video is amazing! Very generous of you to take time and publish this for public viewing. Just out of curiosity is it possible for a user to login via the HostedUI and then have access to api gateway via the browser? If you don't have tech savy customers they likely don't want to access the API via Postman but would prefer to just login and have access, any chance if you know this is possible ? Thanks so much again :)

[@BeABetterDev]

Hi Jonathan, Hm, I don't think this is possible using any out of the box tools unfortunately. Sorry to share the bad news. I think it wouldn't be too much work to create a simple React app with a couple input boxes / text areas to call the corresponding UI once logged in. Thanks so much for the kind words! Daniel
