RSpec test for webhook controllers with basic auth - ruby-on-rails

Question

In my Rails/Grape app I created a webhook controller which receive JSON from CMS webhook. I'm just wondering how to test it in RSpec if I don't have any params (I guess I don't need it because I only receive JSON from webhook).
My webhook controller (it works well):
module Cms
class Webhook < Base
desc 'Take the CMS webhook'
http_basic do |user, password|
user == ENV['USER'] && password == ENV['PASSWORD']
end
post :receive do
params
end
end
end
I was trying to like:
describe Cms::Webhooks, type: :request do
subject(:call) { post endpoint, params: params, as: :json }
let(:endpoint) { '/api/cms/webhooks/receive' }
let(:params) do
{
some: 'some pass'
}
end
it 'returns a successful response' do
call
expect(response).to be_successful
end
end
I'm getting an error:
Failure/Error: expect(response).to be_successful
expected `#<ActionDispatch::TestResponse:0x00007f9058e43e60 #mon_data=#<Monitor:0x00007f9058e43de8>, #mon_data_..., #method=nil, #request_method=nil, #remote_ip=nil, #original_fullpath=nil, #fullpath=nil, #ip=nil>>.successful?` to return true, got false

Can you try this code?
describe Cms::Webhooks, type: :request do
subject(:call) { post endpoint, params: params, as: :son, headers: headers }
let(:endpoint) { '/api/cms/webhooks/receive' }
let(:params) do
{
some: 'some pass'
}
end
let(:headers) do
{
'HTTP_AUTHORIZATION' => ActionController::HttpAuthentication::Basic.encode_credentials('your_username', 'your_password')
}
end
it 'returns a successful response' do
call
expect(response).to be_successful
end
end
