How to query the Criteo REST API v2 in Ruby?

Question

I want to query the Criteo REST API v2.

The answer below indicates that the REST API v2 has not yet been implement by Criteo so i have used v1 instead. Their website says that v1 will be deprecated soon.

The API v1 is described here

The Swagger for API v1 is here

The REST API v2 which I'd really like to use is here

Here is my code at this point:

#! /usr/bin/ruby

require 'net/http'
require 'net/https'
require 'uri'
require 'jwt'
require 'date'
require 'json'

CLIENT_ID = 'mapi-XXX'

CLIENT_SECRET = 'YYY'

end_date = Date.today

start_date = Date.today - Date.today.mday + 1


# first get a valid token

uri = URI('https://api.criteo.com/marketing/oauth2/token')

headers = { 'Content-Type': 'application/x-www-form-urlencoded', 'Accept': 'application/json' }      

https = Net::HTTP.new(uri.host, uri.port)

https.use_ssl = true

https.verify_mode = OpenSSL::SSL::VERIFY_NONE

request = Net::HTTP::Post.new(uri.path, headers)

request.set_form_data( 'client_id' => CLIENT_ID, 'client_secret' => CLIENT_SECRET, 'grant_type' => 'client_credentials' )

response = https.request(request)

access_token = JSON.parse(response.body)['access_token']

 puts access_token



uri = URI('https://api.criteo.com/marketing/v1/portfolio')

headers = { 'Accept': 'application/json', 'Authorization': "Bearer #{access_token}" }

https = Net::HTTP.new(uri.host, uri.port)

https.use_ssl = true

https.verify_mode = OpenSSL::SSL::VERIFY_NONE

request = Net::HTTP::Get.new(uri.path, headers)

response = https.request(request)

puts response.body


uri = URI('https://api.criteo.com/marketing/v1/campaigns?campaignStatus=Running')

headers = { 'Accept': 'application/json', 'Authorization': "Bearer #{access_token}" }

https = Net::HTTP.new(uri.host, uri.port)

https.use_ssl = true

https.verify_mode = OpenSSL::SSL::VERIFY_NONE

request = Net::HTTP::Get.new(uri.path, headers)

response = https.request(request)

puts response.body

json = JSON.parse(response.body)

campaigns = json.map { |campaign| campaign['campaignId'] }


# get statistics

puts start_date # => "2018-12-01" 

puts end_date # => "2018-12-17"

uri = URI.parse('https://api.criteo.com/marketing/v1/statistics')

headers = { 'Content-Type': 'application/x-www-form-urlencoded', 'Accept': 'application/json', 'Authorization': "Bearer #{access_token}" }

https = Net::HTTP.new(uri.host, uri.port)

https.use_ssl = true

https.verify_mode = OpenSSL::SSL::VERIFY_NONE

request = Net::HTTP::Post.new(uri.path, headers)

request.set_form_data( 'reportType' => 'CampiagnPerformance', 'ignoreXDevice' => true, 'startDate' => "#{start_date}", 'endDate' => "#{end_date}", 'dimensions' => ['CampaignId'], 'metrics' => ['Clicks'], 'format' => 'Json', 'currency' => 'USD', 'timezone' => 'GMT') 

#request.body = payload.to_json

puts request.body

response = https.request(request)

puts response.body

Looks like you need to add the following to your headers:

'Authorization': 'Bearer VALID_JWT_TOKEN_BASE64'

Also, they don't appear to have migrated their portfolio API endpoint to v2 yet. I was able to resolve their old v1 endpoint (based on their documentation):

curl -X GET --header 'Accept: application/json' --header 'Authorization: Bearer [token]' https://api.criteo.com/marketing/v1/portfolio

That at least gave me an unauthorized response. Try updating your uri to:

uri = URI('https://api.criteo.com/marketing/v1/portfolio')
