ION - Send files to AWS S3 (Signature Version 4)

Hello,

I have a problem sending a file with ION to AWS S3 with the version 4 signature.

I configured my ION API with the correct connection information to connect to AWS as well as my swagger file.

When I try to retrieve a file with the GET method it works correctly, on the other hand when I try to send data to the S3 bucket (with the PUT or POST methods) I have a problem with authentication and signature.

Has anyone ever uploaded files to an S3 bucket with the version 4 signature?

Thanks a lot for your help !

Hello

I solved my problem.
The test via ION API does not work because it must not send the correct header to aws.

When I tested through my connection point with the right parameters I was able to send data to the S3 bucket.
It was ultimately not a security issue associated with signing up to AWS.

How are you connecting to S3 bucket ? Are you using AWS API Gateway ?

Ahh. Alright. I have done this before where I could push / pull files to / from s3 bucket from ION API. I have used AWS API Gateway to build a REST API endpoint which i used in the ION API Suite.

I discovered that if I include the full end point when the API is created, the signature works in Swagger except for PUT, which requires a file not a string. I downloaded the AWS S3 API JSON, then converted to YAML which is easier to work with, but am still unable avoid header errors if subsequent API method end points are different than the declared end point.

Has anyone succeeded in migrating Amazon's AWS JSON Swagger to YAML then appending the api key and secret key as upload parameters ? I think that would fix the header errors. Has anyone added a file upload parameter to a Swagger definition ?
