Where to update the Access Key

We are having an S3 account and would like to do integrate within our OS.
Can someone tell me where must we update the ACCESS KEY - We would like to have location with screenshots possible.

Is it thru Integration Studio or Service Studio
The AWS Access Key Id you provided does not exist in our records.
Hi Kayala,

Not sure how you're doing the integration, but if you check the AdvancedAmazonS3 component in Forge, you'll see that the extension actions are built to receive the required access key and secret key to connect to S3. You should have something similar (if you're using other extension) and consider passing those values from site properties in your eSpace.

Also, be aware that there seems to be some delay when trying to connect right after creating the access keys - reported here.
