:ManagedCustomerService gives [AuthenticationError.CLIENT_CUSTOMER_ID_IS_REQUIRED] about google-api-ads-ruby HOT 5 CLOSED

You already set it here:

credentials.set_credential(:client_customer_id, load_master_mcc_account)

what you need is to skip use_mcc call, change

result = adwords.use_mcc {service.get(selector)}

to

result = service.get(selector)

We need to update examples for this and restrict calls w/o CID in the adwords gem.

Thank you for quick response, unfortunately nothing changed.
I still having the same error even without 'adwords.use_mcc'

from google-api-ads-ruby.

Just to add, using for example :CampaignService with appropriate selector works ok on master account (it does not have any campaigns tho) and i tried couple of more services.
Only service that gives this error is :ManagedCustomerService.
With and without adwords.use_mcc

from google-api-ads-ruby.

Strange, as there is no special handling for MCS in the library (except to use_mcc())

Can you point us to the exact code you are using?

from google-api-ads-ruby.

Actualy your suggestion worked. Last night, i was to tired and made some mistakes.
Thank you Danial

p.s. Rails example, adwords_on_rails might need some work, seems outdated, no Gemfile etc. Just saying :)
