Link Two MCCs to an AdWords Account

[AdWordsAPIAdvisor]

Over the last several months we've received feedback from API
developers who are unable to link their My Client Centers (MCC) to
their clients' accounts. In every case, these developers were unable
to link to their clients because another MCC (typically an agency's
MCC) was already linked to the accounts. This creates obvious
challenges for the developers as they try to secure API quota credit
for the spend they manage.

Therefore, we would like to announce that we've enhanced the MCC
linking function in order to allow two different MCCs to link to the
same AdWords account.

How does it work?

In order to properly define roles and access privileges under this new
dual-MCC structure, MCC owners will now have to choose one of two
access levels when linking to an AdWords account: "User Interface &
API" or "API Only" access.

While all MCCs will be able to access AdWords accounts via the API,
only the MCC designated for "User Interface & API" access can manage
AdWords accounts via the AdWords interface.

All current MCC links have been automatically granted "User Interface
& API" access (the traditional level of access you are used to).
Therefore, there is no action required of you at this point, and you
may continue to use your MCC as you have in the past.

So what does this mean for AdWords API developers?

API developers who co-manage accounts with partner agencies can now
receive credit for 100% of an account's spend toward their API quota.

How will this affect quota calculations?

How you link to a client account will impact your monthly API quota
allocation.
-- If you are the only MCC linked to a given account, then we will
apply 100% of that account's spend towards your API quota.
-- However, in a situation where there are two MCCs linked to the
same account, the "API Only" MCC be credited 100% of that
account's spend towards their API quota, and the
"User Interface and API" MCC be credited 10% of that
account's spend towards their API quota.

Therefore, if you are the sole manager of an account, then you are free
to choose either access level (since, as the sole MCC manager, you can
claim 100% of the account's spend toward your API quota no matter which
access level you have).

However, if you are a bid manager or API developer who co-manages an
account with a "traditional" agency, then you should link to your
clients' account using the "API Only" access level (so you can
ensure that 100% of the account's spend is credited toward your API
quota).

How do we get started?

This functionality is available today under the "Link Existing
Account" link on your My Client Center dashboard. Next time you
attempt to link to an account, you will have to specify whether you
want full user interface and API access, or simply API-only access.

Some Final Notes

-- Account managers can run MCC Report Center reports on
all of their linked accounts (regardless of whether those
accounts are linked via "User Interface & API" or
"API Only" access)
-- Two MCCs cannot both establish an "API Only" link to the
same AdWords account.
-- For account security reasons, you cannot create an
"API Only" link between two MCCs.

Thank you again for your support of the AdWords API, and we hope you
find this new feature useful.

Rohit,

We need the ability to add an existing client account to our MCC via an
API. This request first appeared on this board in July, and the
response was the API was not available. Are you planning to add this
API?

Thank you,
Dmitry

After linking an account to an MCC as API only, a call to
getClientAccounts() does not return this account in the list. Is this
expected behavior?

If an account is linked as API only, will that account have data in an
all account MCC level custom report through the API?
