i am getting "Internal server error"
I know the ui looks different, but my guess is that this is most likely configuration related
Exactly what i was looking for.. Thanks a lot
Glad it helped
one of the smoothest tutorials. i'm shaking your hand virtually!
Happy to hear that!
Does anyone know how to do the same with Terraform?
I sure there are some yaml samples out there. Unfortunately I don't have any.
Why do you use the path override {bucket}/{filename} for your child resource {filename} if you already gave your endpoint these same structure /{bucket}/{filename}. An action name in your method of your {filename} would have been good enough right?
I guess just for demo purposes...but good point.
I don't have the "Create policy" button from 2:37 .. any ideas why?
They changed the ui a while back...it might look different now.
Thanks a lot! That's exactly what we need. We want to use Amazon S3 with an existing Keycloak instance and use JWT Token authentification
Glad it was helpful
was there a change in AWS UI, I am having a problem creating api resource as path parameter using {}?
Yes they changed the ui a while back
This was incredible. It would have taken approximately 1 million years to figure this out by reading the docs alone. You're a hero.
Glad you found it helpful

Does anyone have this code for Java?
I dont, but you can easily copy it into chat gpt and ask it to convert it to java for you.
Hi all, I'm pretty new. I followed all these steps, made sure that my S3 and API endpoint are in the same region and yet, I still keep getting this error: The bucket you are attempting to access must be addressed using the specified endpoint. Please send all future requests to this endpoint I'm trying to upload a JSON file. Have any of you had this issue?
I have never encountered this issue. In readibg your error, this looks to be endpoint uri related or something wrong with the endpoint permissions.
@@letsfindsolutions Hi, it was something with the permissions :) Thanks for your reply, I was able to resolve it <3
genioooooo!!!, gracias loco
Gracias
It is uploading the file into but there are some issues m facing: 1) even if am specifying the content type in Binary-media-type (audio/mp3), still m able to upload any file 2) the file gets corrupted when it's uploaded I tried form postman and even tried using flutter
Possibly the encoding is messing up somehow...aside from that i. Not really sure what else it could be.
The AWS Cognito interface has changed, the setup is very different from what's shown in this video.
Agreed, the screens have changed...but the concept is essentially the same. When i have time i will do an updated video.
I have implemented Cognito authentication for my .net web api / react app. It's in .net 4.8 framework and hosted in iis localhost. Also using IIS Url rewrite to configure IIS that react router handlea the app navigations after authentication is completed. Issue is when we make Cognito logout api endpoint get request, it throws CORs error stating Allow Content Header Origin is not present. I have the proper app domain, client id and redirect uri. So what needs to be done in this situation for logout to work. Cognito login works perfectly
Did you try enabling cors on the api gateway?
Keep it up. Informative video👍
Thanks, will do!
why implicit grant rather than Authorization code grant? Aws doesn't recommend using Implicit Grant
We are using jwt tokens. In not sure on the question.
i want to do OTA update by giving this the url of the uploaded firmware file. is this method ok for that? what happened if I just upload the binary file?
This methid requires a valid jwt token...so as long as you can authenticate and pass along a token this will work.
How can i use this token further in aws lambda to get the email id or username to do some dynamic processing? Are there any cognito sdk or library available to scrap that Information in aws lambda ?
I believe you can get the user id or group id of the user from the token. From their you can have a dynamo db table to do mapping and dynamic logic based on your custom lookup.
Seems like you can get it from event.requestContext.authorizer
Thanks a lot for this video. I've a question about authentication. Here, the REST API call from postman worked as we have given the IAM role with putobj policy. How about if I have to restrict the upload to a specific user? Say, the upload happens from a custom web application, the user uploads the file, is there a way to include IAM user authentication here? Could you please give any pointers to this?
You could use a lambda authorizer (formerly known as custom authorizer). Here you have full control of the auth logic and can validate your keys against specific groups or users.
@@letsfindsolutionsThank you!
Absolutely the content am looking for.. I also would like to know how to write custom response body in postman when status code is "200 OK"
You would need to write a custom lambda for that.
Thank you man Actually i am trying this its works on postman ,but i want to use API gateway endpoint in my JS code can you please suggest me .
You could just use a library like axios or just use jquery ajax calls to the api. Keep in mind this expose your keys, so really its best to have it call your own back end layer which then calls your api to keep the keys hidden.
nice, no nonsense, no silly accent, 10/10 thank you sir
Thank you kindly
Just curious, what's a silly accent?

@@zishanchaudhary221 Ohhh, so you guys are neanderthals complaining about free instructional material. Got it
Thanks a lot! Very concise and to the point! 👌
Glad it was helpful!
thanks for the great video, I'm starting a project where I'll need to use S3, why use the API Gateway and not S3's own REST API?
I had a use case to use a custom authorizer, so api gateway allows for this type of configuration.
So insightful! Thank you.
Thanks
7:53 When you change the password the second time, it says 'localhost has refused to connect'. How can I solve this? 8:44 I tried it on Postman, but I couldn't get the token's value and it came out the same way
Not really sure of the issue...just make sure you are using the id token and not the access token. Postman finally updated the ability to use the id token...so maybe try again.
When I give a path resource, it does not get it
Maybe try recreating it. Sometimes that helps.
@@letsfindsolutions by the way thak its help
i am also facing same problem while creating resource in API gateway can't add brackets with bucket in resource path, same with filename , my resource path is not taking brackets or I can say anything . error invalid mapping expression parameter specified can you help me
@@gurpreetkaur-cw8woWhen creating a resource, simply write the name within {} brackets, and it will work.
Hi @letsfindsolutions Your video is like, follow me. Crisp and up to the point. It took hardly 20min to reproduce what you have explained. Wish to see more video from you.
Will eventually add more when I get time.
Nice and to the point
Thanks!
Top quality stuff!
Much appreciated!
Straightforward and awesome video
I am glad you found it helpful. I do plan on making more, just need to find the time.
Great video. Great content and well executed and straightforward. Well done.
Glad you found it helpful.
AWS UI changed now. Cognito UI looks entirely new and unable to get published the user login page.😥
See if you see the option for classic mode...if so you xan switch back to that view maybe
You saved the day! I had t use oauth 2.0 in postman and not the bearer token dropdown
Glad you found it helpful.
i am getting internal server error while calling the api. is it something to do with WAF or ListWebACLs?
Internal server error leads me to believe maybe code related...did you modify the sample code?
@@letsfindsolutions there's no code..i followed your steps.. m getting a WCL error on the screen tho,,,could it be the issue? or it seems like s3 access isue
Ya could be s3 permission issue
great video and thanks for sharing. I would like to upload via browser instead of postman, is there any way to api via browser ?
Yes, you would need to build a front end ui...like a react ui web page that can make calls to the api similar to postman.
@@letsfindsolutions can you tell how to do that in Vue.js , i tried a lot, didnt get any solution
In this method, can anybody in the world upload to my bucket? What if i wanted to restrict it to just myself? Using an access token or api key?
With api gateway you can enable an Authorizer and have it validate a token i the header. You can setup cognito to work with the authorizer to validate the tokens.
Look at my other video about jwt authorizer....you would use the same approach there.
How can I get the content of the file in the bucket using the api? I mean GET method
You would need to write a new get method to read and serve back the content.
Thanks it works for me, now problem i am facing is, once file upload to s3 bucket i can see file, but when i use to open that file with object url than my file is not opening, its giving me error like access denied so let me know how to give public writes to view that file simultaneously.
I believe you will need to update the permissions of the s3 bucket to allow for public read.
@@letsfindsolutions Thanks i done yesterday only by myself by creating policy
no it did not work time wasted
Sorry to hear it did not work for you.
Hi there, I just switched to the updated console for API Gateway and tried to get the same scenario, but over there, it is not allowing me to give the Path override field as {bucket}/{filename} rather just the {bucket}. Also after deploying the API Gateway, I am getting this error: <?xml version="1.0" encoding="UTF-8"?> <Error> <Code>MaxMessageLengthExceeded</Code> <Message>Your request was too big.</Message> <MaxMessageLengthBytes>10240</MaxMessageLengthBytes> <RequestId>5KN0W9VZX436B9S8</RequestId> <HostId>K1j8PseM9Rxky8woHv6VjSH2zAU1ta7Raqk9nOJF7untXTnoFN/0y7ngSAMp0jBX4BU7xZiuG6Y=</HostId> </Error>
sir , you are a life saver , thank you
Glad you found it helpful.
what are configuration for your stage of dev? And my problem is that file successfully upload but size is 0kb so any solution?
What are you using to test the upload? In the video I use postman and i believe all its doing is converting the data to base64 encoded binary data. Similar to what a web browser would do.
Thanks @@letsfindsolutions
While Edit integration request to add URL path parameters when click save it showing Network Failure( Anyone help Currently I am Using ap-south-1 Region ) i don't know what is the problem ??
Not sure im understanding the iasue...but maybe try switching regions. I usually use us east.
@@letsfindsolutions I tried us east also but it's not working in api gateway
i am also facing same problem while creating resource in API gateway can't add brackets with bucket in resource path, same with filename , my resource path is not taking brackets or I can say anything . error invalid mapping expression parameter specified
I resolve my problem put path in single inverted comma '' that will work as i am not getting option to put curly brackets
It should return the link for access the file
That can be customized if needed
This is really great video. I have few questions 1. Did you pass any token in header for validation. 2. I can give this url to upload file to anyone, whether he is a AWS user or not
1. There is no security around it so no token is needed. You can add cognito security with an authorizer to validate a token if needed. 2. Yes the url is public and open. It can be called like any other api publicly. They do not need to be anaws user.
@@letsfindsolutions many thanks.
I am glad you found the video helpful...I really do plan to make more...just haven't found the time to lately.
Thanks for this solution. I have implemented this for MS excel file upload but the size got change every time. Can you please help me out with the solution for that. Facing the issue with format change and file size got increased during upload.
Did you follow the video...what media types have you defined?
@letsfindsolutions I have allowed all media types. But only for Excel, it got format change happens
Maybe the encoding ia somehow getting changed on upload...excel would be similar to other binary files.
good one, thank you
Glad you liked it!
How would it be via POST, to send file via base64 string?
I think you can change the method to a POST and just add in additional media types to handle the base64 encoded data being passed.
