We toggle between multiple keys but it appears the library is working against us in many cases.

1. Omise.api_key must be set (I found issue #19 with an identical problem but it was cryptically closed without documenting the solution)
2. Omise::Charge.retrieve('chrg_xxxxxx', key: 'xxxxxxxx') works, but calling charge.transaction on the result results in a transaction not found error, unless I repeat the key with charge.transaction(key: 'xxxxxxxx')
3. Omise::List object doesn't retain the key when I paginate with next_page, and this one doesn't even accept the key parameter

There is a small typo in the link to Omise.js there. It's written gitub instead of github.

It would be good to have some default timeout for RestClient::Resource.new

Relatively sensible values could be:

 :open_timeout => 15 # Connection time
 :read_timeout => 60 # Response time

Since a transaction will never be higher than 60 seconds, and connecting to the API should not be longer than 15 seconds.

there was error on rest-client 1.8
I'm on ruby-2.4.1 so OpenSSL::SSL::SSLContext::DEFAULT_PARAMS not include :ciphers key

https://github.com/rest-client/rest-client/blob/v1.8.0/lib/restclient/request.rb#L159-L166

When querying the list resources, the pagination attributes are not taken into account.

for example, when issuing this list api call:

Omise::Charge.list(from: "2015-04-01", to: "2015-05-01", limit: 2, offset: 1)

Response gives out 20 results, ignore the attributes and date filtering.

I need to use multi key. So I decided to send key with method option.

When I skip to set Omise.api_key I got error like picture below.

It seem like Omise.api_key need to be empty string at least.

Does it Have the other way to skip to set Omise.api_key?

Running this sample code from https://www.omise.co/charge-schedules-api

require "omise"

Omise.secret_api_key = ENV['OMISE_SECRET_KEY']

scheduler = Omise::Charge.schedule({
  customer:    cust_test.id,
  card:        card_test.id,
  amount:      100000,
  description: "Membership fee"
})

schedule = scheduler.every(1).month(on: "2nd_monday")
  .start_date("2022-11-01")
  .end_date("2022-12-31")
  .start

Raises this error:

Traceback (most recent call last):

Hi

when Omise::Token.create method is succeed, it returns json
but when failed, it returns text format

so it causes JSON::Parser error on my rspec

JSON::ParserError: 822: unexpected token at '
from /Users/xxxx/.rbenv/versions/2.4.7/lib/ruby/gems/2.4.0/gems/json-1.8.6/lib/json/common.rb:155:in `parse'
```

I found in wiki to set
Omise.api_key = "skey_test_4xa89ox4z4bcfrikkh2"

but after try out a little bit i found that should use "Omise.vault_key" instead

;D
