Load an Endpoint

Click any quick-access button in the bar above (Lists, Reports, Meta), or type an endpoint name manually and press Enter.

Use ▶ Load for a quick first-page preview, or ⬇ Load All to fetch every record. Use Load All before building a prompt.

⚠ Manager.io returns max 50 records per API call. Load All follows every page automatically so you never miss fields.

💡 Click any field name to copy its dot-notation path to clipboard.

⚠ Important Disclaimer

🛠 Developer-focused tool. Designed for users who understand APIs, JSON, and basic web concepts.

🤖 AI can and does make mistakes. The generated prompt is a best-effort starting point. Always review and test generated code before using it with real business data.

📉 Output quality varies by model. Paid plans (Claude Pro, ChatGPT Plus) consistently produce better, more complete code than free tiers.

🔁 Iteration is normal. Complex extensions often need 2–3 rounds of refinement. Paste the output back with follow-up instructions.

Provided as-is. Use generated code at your own discretion. Keep a backup of your Manager.io data before installing custom extensions.
