Clarify Per Request Configuration for Custom Requests

[sandstrom]

Great if you could add examples for #create, #new and custom actions (#attach for example) in the readme under the per request configuration section, along with the existing ones.

I tried to get them running with a custom API version and had to read through source-code to figure it out.

For example, the this stuff wouldn't work (I know why now, but it took a while):

Stripe::PaymentMethod.attach({
  :id => stripe_payment_method.id,
  :customer => billing_entity.provider_identifier,
}, { :api_key => 'sk_test_' })

Hi sandstrom, thanks for the report!

We do have an example of how to e.g. use Stripe::PaymentMethod.attach here in our api reference. If we mentioned the example requests and linked to the API reference in the "Usage" section of the README.md, would this have helped you figure out how to use the method more easily? Eg #875?

@richardm-stripe sorry, I was unclear, I ment this stuff: https://github.com/stripe/stripe-ruby#per-request-configuration

Looks like @joeltaylor is working on this in #876!

Looks like this was fixed in #876.
