Free CAPI Tools

Pick a canonical conversion event, fill the fields, and see the exact JSON payload adscapi builds — before you write a line of code.

Type a raw email or phone number and see the normalized value plus its SHA-256 hash — the exact rules adscapi applies per platform. Nothing leaves the browser.

Search all 26 ad platforms adscapi dispatches to — support level, required secrets, and setup docs, always in sync with the library registry.

Paste a URL or click ID — fbclid, gclid, msclkid, ttclid — and see which platform it belongs to and what adscapi captures server-side.

The exact Conversions API request adscapi sends per platform — endpoint, headers, and JSON body for a real purchase event, straight from the library dispatchers.

Build tagged campaign URLs with utm_source, medium, and campaign — plus the click IDs (fbclid, gclid) adscapi captures server-side. Copy and share.

Generate a stable event_id to send from both the browser pixel and the server Conversions API, so every platform deduplicates the two into one conversion.

Check which identity fields you send — email, phone, external ID, click ID, IP — and estimate your Event Match Quality, with the fields to add to raise it.

Enter ad spend, conversions, and average order value to compute ROAS, cost per acquisition, revenue, and your break-even CPA. Runs in your browser.
