This gem provides some level of abstraction to Marketo REST APIs. Please note that this gem is alpha quality.


Add this line to your application's Gemfile:

gem 'mrkt'

And then execute:

$ bundle

Or install it yourself as:

$ gem install mrkt


Get the following from your Marketo admin:

  • hostname, i.e. ''
  • client id, e.g. '4567e1cdf-0fae-4685-a914-5be45043f2d8'
  • client secret, e.g. '7Gn0tuiHZiDHnzeu9P14uDQcSx9xIPPt'
  • partner id, e.g. '335b1c91511b8d8b49c7bbf66f53288f16f37b60_a0147938d3135f8ddb5a75850ea3c39313fd23c4' (optional)


Create a client and authenticate

client =
  host: '',
  client_id:  '4567e1cdf-0fae-4685-a914-5be45043f2d8',
  client_secret: '7Gn0tuiHZiDHnzeu9P14uDQcSx9xIPPt',
  partner_id: '335b1c91511b8d8b49c7bbf66f53288f16f37b60_a0147938d3135f8ddb5a75850ea3c39313fd23c4' # optional 

If you need verbosity during troubleshooting, enable debug mode:

client =
  host: '',
  client_id:  '4567e1cdf-0fae-4685-a914-5be45043f2d8',
  client_secret: '7Gn0tuiHZiDHnzeu9P14uDQcSx9xIPPt',
  debug: true,
  logger:"log/marketo.log"), # optional, defaults to Faraday default of logging to STDOUT
  log_options: {bodies: true}) # optional, defaults to Faraday default of only logging headers

Retry authentication

Since the Marketo API provides API access keys with a validity of 3600 seconds, if you are running an hourly cronjob it's possible that your subsequent call receives the same key from the previous hour, which is then immediately expired. If this is the case, you can configure the client to retry until receiving a valid key:

client =
  host: '',
  client_id:  '4567e1cdf-0fae-4685-a914-5be45043f2d8',
  client_secret: '7Gn0tuiHZiDHnzeu9P14uDQcSx9xIPPt',
  retry_authentication: true,
  retry_authentication_count: 3, # default: 3
  retry_authentication_wait_seconds: 1, # default: 0

This is turned off by default.

Get leads matching an email, print their id and email

response = client.get_leads(:email, ['[email protected]'])
response[:result].each do |result|
  p "id: #{result[:id]}, email: #{result[:email]}"

Create/Update leads

response = client.createupdate_leads([{ email: '[email protected]', firstName: 'John' }], lookup_field: :email)
response[:result].each do |result|
  p "id: #{result[:id]}, email: #{result[:email]}"

Run a smart campaign on existing leads

campaign_id = 42        # this is the ID of the campaign
lead_ids    = [1, 2, 4] # these are the leads who receive the campaign
tokens      = [{        # these tokens (optional) are then passed to the campaign
                 name:  '{{my.message}}',
                 value: 'Updated message'
               }, {
                 name:  '{{my.other token}}',
                 value: 'Value for other token'
client.request_campaign(campaign_id, lead_ids, tokens) # tokens can be omited
=> { requestId: 'e42b#14272d07d78', success: true }
