It seems like you're having trouble connecting to the Google Ads API with your provided configuration. Based on the information you provided, you have a manager account that manages different client accounts, and you've filled in the "Login Customer ID for Managed Accounts" field with a client account ID. To set up the Google Ads source in Airbyte, you need to provide the Customer ID(s) for your account and the Login Customer ID for Managed Accounts (if applicable). Here's a summary of the steps you need to follow: 1. Log into your Airbyte Cloud account. 2. Click Sources and then click + New source. 3. On the Set up the source page, select Google Ads from the Source type dropdown. 4. Enter a Name for your source. 5. Click Sign in with Google to authenticate your Google Ads account. 6. Enter a comma-separated list of the [Customer ID(s)](https://support.google.com/google-ads/answer/1704344) for your account. 7. Enter the Start Date in YYYY-MM-DD format. 8. (Optional) Enter a custom [GAQL](https://docs.airbyte.com/integrations/sources/google-ads#custom-query-understanding-google-ads-query-language) query. 9. (Optional) If the access to your account is through a [Google Ads Manager account](https://ads.google.com/home/tools/manager-accounts/), enter the [Login Customer ID for Managed Accounts](https://developers.google.com/google-ads/api/docs/concepts/call-structure#cid) of the Google Ads Manager account. 10. (Optional) Enter a [Conversion Window](https://support.google.com/google-ads/answer/3123169?hl=en). 11. (Optional) Enter the End Date in YYYY-MM-DD format. 12. Click Set up source. In your case, make sure you enter the Customer ID(s) for the client accounts you want to access in step 6, and the Login Customer ID for Managed Accounts (the manager account ID) in step 9. If you're still having issues, please double-check that you have the correct Customer IDs and Manager Account ID, and that your manager account has the necessary permissions to access the client accounts.
