See last bullet in "how to get help" section at http://camel.apache.org/support Apache is a 100% open community, and its important that all conversation happens in the open, and on Apache infrastructure (eg mailing list / JIRA / etc) - so everybody can follow. > It seems that the answer is "yes," and that the Camel documentation does > not reflect this.

For example using plain java code, with getter/setter etc. But most people favor using the uri syntax directly in their routes. And when you do that then care should be taken when using special characters like + and % signs etc. The RAW() syntax tells Camel to leave the uri normalized out of that part, and the user want the data as-is. So if your AWS keys are using such chars, then RAW is the correct way to do that, if you configure using uri style. And Apache loves contributions, so you are welcome to fix/help with the docs, in case you think the AWS page need some help http://camel.apache.org/contributing For example from the user guide there is the "how do i configure endpoints" http://camel.apache.org/user-guide.html which documents the RAW () in endpoint uri style http://camel.apache.org/how-do-i-configure-endpoints.html > > References: > > [1]: <https://issues.apache.org/jira/browse/CAMEL-4954> > "CAMEL-4954: Camel 2.9.0 incapable of working with % in endpoint URIs" > [2]: <https://tools.ietf.org/html/std66#section-2.1> > "IETF STD 66: URI Generic Syntax: 2.1.
