Common Questions
Why isn't my API key working?
Double-check that you've copied both the Site ID and API Key correctly without any extra spaces. Ensure the key has the "Reporting" scope enabled. If issues persist, try generating a new API key in your Customer.io account settings.
Why don't I see any campaigns or data?
Make sure you have sent campaigns within your selected date range. Customer.io's API may take a few minutes to update metrics after sending. Also verify that your API key has the correct "Reporting" permissions to access campaign statistics.
What if I'm getting timeout or rate limit errors?
Customer.io has API rate limits to protect their servers. If you're experiencing timeouts, try selecting a shorter date range or wait a few minutes before generating another report. For large accounts with many campaigns, consider breaking your analysis into smaller time periods.
Is my data secure?
Yes. We only request read-only access to your campaign statistics through the Reporting API. We never have permission to send emails, modify campaigns, or access customer personal data. Your API key is encrypted and stored securely. You can revoke access at any time from your Customer.io account.
Can I disconnect my account later?
Absolutely. You can disconnect your Customer.io account anytime from your Email Calculator settings page. Simply remove the integration and your API credentials will be deleted from our system. You can also revoke the API key directly in your Customer.io account settings.
