Upgrading to 3.0

[tdtadeu]

I opened this issue so we can debate it here. I accidentally started the discussion at #33, but I didn't want to go on there since that issue asks for something different, yet related.

V3 is RESTful, at last! https://developers.activecampaign.com/reference

@mhenrixon Should we maintain the same structure of method call using method_missing in the main module, or could I suggest we create resource classes to map their new API?

[mhenrixon]

@tdtadeu I'm fine with using something more real for v3. I wanted to do it for the longest time. That said I wouldn't go too crazy with it.

The simplest thing possible.

For instance, I rather focus on rescuing errors and mapping that to something useful than adding validations in the gem.

Are there any plans on updating this gem to use V3 of the API?

Thanks!

[mhenrixon]

@mikevalen Yeah but there is no time unfortunately. If I can manage to free up enough time I'll do it but right now I have to focus on paid work since I don't use Active Campaign at work anymore.

Possible to issue a gem release?

[mhenrixon]

@kjanoudi needs a few more endpoints first

@mhenrixon and @kjanoudi I can help you guys finishing this integration. Can you list me what is missing?
