First-time setup

Ask your AI client: 
Connect my Google Ads account to HireOtto.
HireOtto will return an authorization URL.
  • Open it, sign in with the Google account that has access to your Google Ads, and complete the consent screen.
  • After consent, you’ll see a list of all accessible accounts — you can select all of them or pick specific ones, then SAVE.
    • This step is important: if you skip saving, HireOtto won’t have any accounts to work with even though the OAuth itself completed successfully.
  • Once saved, come back to your client — you’re connected.
If you have not added HireOtto to your AI client yet, start with Connect Google Ads MCP. If you are setting up Claude, ChatGPT, or Make specifically, use Connect HireOtto to Claude, ChatGPT, and Make.

How HireOtto resolves accounts

When you connect a Google login, HireOtto looks one level down from each account it can see:
  • Direct Google Ads accounts are included as-is
  • If any of those accounts is a Manager account (MCC), HireOtto also includes all the child accounts directly under it
So a single connected login can give you access to your own accounts plus all client accounts under a Manager — without any extra setup. Where this stops: if your MCC contains another MCC (a nested Manager hierarchy), HireOtto won’t automatically traverse further. To access accounts at that deeper level, you need to connect a separate Google login that has direct access to the inner MCC. See Connecting multiple Google logins below.

​
Connecting multiple Google logins

There are two common reasons to connect more than one Google login:
  1. Deep MCC hierarchies — you have an MCC inside an MCC, and the outer login can’t reach the inner accounts directly
  2. Access spread across multiple Gmails — you or your team have client account access granted to different Google logins, and you want all of them available through one HireOtto connector
In both cases, the setup is the same: connect each Google login as a separate profile with a nickname. 
Connect another Google account. Call it "client_mcc".
HireOtto will generate a second authorization URL. Complete the OAuth flow with that Google login, select the accounts you want to save, and you’re done. Repeat for as many logins as you need. Example: three-level MCC hierarchy Say you have this structure:
  • Level 0: Your agency MCC — accessible via your primary Gmail
  • Level 1: A client’s MCC — accessible via a separate Gmail
  • Level 2: The client’s individual accounts under their MCC
Your primary Gmail gets you to Level 0 and everything directly under it. But to reach Level 2, you need to connect the Gmail that has direct access to the Level 1 MCC: 
Connect another Google account. Call it "client_level1_mcc".
Sign in with that Gmail during OAuth, save the accounts — HireOtto will now see the Level 2 accounts under that MCC. One important note: connecting the same Gmail twice under different profile names won’t help — you’ll get the same account access either way. The key is using a different Google login that actually has direct access to the deeper MCC. Profile name tips
  • Keep it short and memorable: agency_mcc, client_ops, jane_gmail
  • Avoid colons (:) — they’re used internally
  • Multiple profiles require the Agency plan

​
Refreshing accounts after adding new ones

If you’ve been granted access to a new Google Ads account after your initial setup, HireOtto won’t see it automatically. Tell your client: 
Refresh my Google Ads accounts.
To refresh accounts for a specific connected login: 
Refresh accounts for [email protected].

​
When auth breaks

Common signs something’s off:
  • You see an error like Google Ads isn't connected
  • list_accessible_accounts returns an empty list
  • Requests fail with a permissions or authentication error
The most common cause: completing OAuth but not saving any accounts during the flow. Re-run auth and make sure you select and save accounts before finishing: 
Re-authenticate my Google Ads account.
If a specific connected login is failing: 
Re-authenticate [email protected].

Frequently asked questions

Does HireOtto store my Google credentials? No. HireOtto uses OAuth tokens — not your Google password. You can revoke access at any time from your Google account security settings. Can I connect a Google Ads Manager account (MCC)? Yes. Connect the Google login that has access to the MCC. HireOtto will include the MCC itself plus all accounts directly under it. For accounts nested under a second-level MCC, connect a separate Google login that has direct access to that inner MCC. I completed OAuth but my accounts still aren’t showing up. You likely didn’t select and save any accounts during the OAuth flow. Re-authenticate, and when you reach the account selection screen, make sure to select the accounts you want and confirm the save before returning to your client.
