FAQ

What authentication method does Campayn use?

Campayn uses API key authentication. You'll find your API key in your Campayn account settings. There is no OAuth flow — you paste the key directly into Coupler.io when setting up your data flow.

Can I pull data from multiple Campayn accounts into one destination?

Yes. Add multiple Campayn sources to the same data flow and use the Append transformation to combine the data. This is useful if your organization manages separate Campayn accounts for different brands or regions.

Does Coupler.io pull individual recipient-level engagement data?

No. Campayn's API provides campaign-level report data, not per-recipient data. You'll see total opens, unique opens, clicks, bounces, and unsubscribes per campaign — but not which specific contact opened or clicked.

Which entity should I start with for campaign performance reporting?

Start with Reports for the engagement metrics, then add Emails as a second source in the same data flow and join them on campaign ID. This gives you subject lines and send dates alongside your open and click rates in one clean table.

Can I send Campayn data to an AI tool for analysis?

Yes. Coupler.io supports AI destinations including ChatGPT, Claude, Gemini, Cursor, Perplexity, and OpenClaw. You can route your Reports or Contacts data directly to these tools to generate campaign summaries, spot trends, or draft insights.

Why does my Contacts entity have more rows than my Lists subscriber count?

The Contacts entity includes all contacts in your Campayn account regardless of their subscription status — active, unsubscribed, or bounced. The Lists entity shows only the count of active subscribers per list. Filter the Contacts entity by subscription status if you want to compare like-for-like.

How often should I refresh my Campayn data?

It depends on your send cadence. For weekly senders, a daily refresh is plenty. For daily senders, a refresh every few hours keeps your dashboards current. Keep in mind that engagement data (opens, clicks) continues to accumulate for 24–48 hours after a send, so don't judge a campaign too early.

What destinations can I send Campayn data to?

Coupler.io supports Google Sheets, Microsoft Excel, BigQuery, Looker Studio, and AI destinations including ChatGPT, Claude, Gemini, Cursor, Perplexity, and OpenClaw. Choose based on how you plan to use the data — dashboards, spreadsheets, data warehouses, or AI analysis.
