Looking pretty good so far! How do you want to handle sending SMS?

[oleksiireshetnik]

Created a separate PR for sending sms (for easier review): #1941

[aeneasr]

This looks good on a high level (will need to dig into the tests still)! Could you also please add some docs for this feature, probably around here https://www.ory.sh/kratos/docs/concepts/email-sms#sending-sms?

[nicolasburtey]

this PR/features is awesome. we (https://github.com/GaloyMoney/galoy) will likely switch to Ory once this is done.

Look forward to this update. Come on.

Removed PR from draft status, added validation and test.

Have one problem with failing docker image scanner, but it is related to protobuf package which was not changed in this PR (also you can check out anchore/grype#558, seems like this failing check is false-positive).

@aeneasr please, review once again

Yes, that is indeed a false positive. No problem. The e2e test is also flaky 😅

How would you like to continue with the other SMS PR that is going on? Do we merge this one, then rebase the other? I have time to review tomorrow :)

[aeneasr]

Scanning over the code quickly, this looks good to merge 🎉

I will do another pass tomorrow but I think this is a no-brainer in terms of merging, great job :)

[oleksiireshetnik]

Yep, I am finishing the pull request with the courier now - encountered a few errors
