I thought the alerts table was already using this API? How were they using it if we weren't exposing it? Or was it through the backend?

[jonathan-buttner]

Do we want to convert to camel case and decode it to ensure it's in the correct format?

[cnasikas]

I thought it would be a good time to break this pattern. Do you think I should camelcase the response? I forgot about the decoding. Thanks!

[jonathan-buttner]

I love the idea of not doing the camel case conversion anymore haha. Yeah let's not do it anymore. I think I saw you already had an issue to remove the others right?

[cnasikas]

Nice! Yes this one here #152706.

This is for o11y. The alerts table cannot use the cases client as cases depend on the alerts table and it will create a circular dependency. Ideally, we should export our APIs to a package so both of them can access them.
