Hello @Kotwic4 ,

Thank you very much for your submission. We definitely plan to implement this feature for the AWS CPP SDK.
I have marked this feature request as a p3 as this feature is pretty new (as you can see this has only been implemented in the CLI and python a couple of weeks ago) and is an enhancement with an available workaround.

I will keep you updated on the status of the implementation here!
If anyone would like to showcase their interest interest for this Feature you can do so by adding a thumbs up to the issue submission.

Best regards,

Yasmine

Hi @yasminetalby - it's now 2025, AWS_ENDPOINT_URL has been around for over 18 months, and the AWS SDK for C++ is the only current AWS SDK that does not support it (see Service-specific endpoints). Could we move this along? It's a nuisance to have to make code changes rather than set an environment variable when we need to use an alternate endpoint URL.

AWS, can we please make this happen? I'll also ask our AWS Contacts why this doesn't get prioritized after over 18 months.
