## FAQs

<Accordion title="What currency should I use for budget amounts?">
  Use the same currency as your Google Ads account. The node will apply budgets in your account's default currency (USD, EUR, GBP, etc.). Check your Google Ads account settings to confirm your currency.
</Accordion>

<Accordion title="What's the minimum and maximum budget I can set?">
  Google Ads has minimum and maximum budget limits:

  * **Minimum**: Varies by currency (typically \$1-5 USD equivalent)
  * **Maximum**: Varies by account and campaign type

  The node will report an error if you try to set a budget outside these limits.
</Accordion>

<Accordion title="How do I bulk update budgets based on performance?">
  1. Use **Get Report** node to fetch campaign performance data
  2. Use **AI Analyze Data** to calculate new budget recommendations
  3. Connect the output to this node using structured data format
  4. Ensure your data includes `campaign_id` and `budget` columns
</Accordion>

<Accordion title="What's the difference between structured data and manual mapping?">
  * **Structured data**: Your data source contains both campaign IDs and budgets in a single dataset
  * **Manual mapping**: You have separate data sources for campaign IDs and budgets (matched by position)

  Use structured data when your analysis output includes both fields. Use manual mapping when you have separate lists.
</Accordion>

<Accordion title="Can I update budgets across multiple accounts?">
  No. Each node instance works with one Google Ads account. To update budgets across multiple accounts, use separate nodes for each account.
</Accordion>

<Accordion title="What happens if a campaign ID doesn't exist?">
  The node will report an error for invalid campaign IDs but continue processing valid ones. Check the output for any failed updates.
</Accordion>

<Accordion title="Do budget changes take effect immediately?">
  Yes. Budget changes take effect immediately in Google Ads. Your campaigns will start using the new daily budget right away.
</Accordion>

<Accordion title="Can I set decimal budget amounts?">
  Yes. You can set budgets with decimal places (e.g., 75.50, 100.25). This is useful for precise budget allocation based on performance calculations.
