How to verify the response from api while writing test with Cucumber - ruby-on-rails

Question

I am working on a Rails project where I have to test the API with Cucumber. I have to test a POST type API and I need to verify its response. I have tried something like:
When(/^I make abc API call$/) do
#url = 'http://example.com/api/abc'
#params = '{
data: {
type: "abc",
attributes: {
title: "example",
all_day: "0",
start_date: "1409175049",
end_date: "1409175049"
}
}
}'
#login_token = 'pHufpGplLTYJnmWh5cqKoA'
end
Then(/^It should return success for abc$/) do
post 'http://example.com/api/abc', body: #params,
headers: { 'Accept' => 'application/json',
'login_token' => #login_token,
'Content-Type' => 'application/json' }
end
But I am not sure how to verify the status code from the response and any attributes from the response. Something like:
Then(/^It should return success for abc$/) do
post 'http://example.com/api/abc', body: #params,
headers: { 'Accept' => 'application/json',
'login_token' => #login_token,
'Content-Type' => 'application/json' }
.to_return(status: 200, body: '{ title: "abc" }')
end
How can I achieve it?

If you are using Capybara this should work for you:
Then /^I should get a response with status (\d+)$/ do |status|
response = post 'http://example.com/api/abc', body: #params,
headers: { 'Accept' => 'application/json',
'login_token' => #login_token,
'Content-Type' => 'application/json' }
response.status_code.should include(status.to_i)
end
