Voluum

Voluum is a click-id-based ad attribution tracker popular for cross-network media buying. TagadaPay’s integration fires a single S2S postback to Voluum every time an order is paid.

​
Setup

1

Find your Voluum tracking domain

In Voluum: Settings → Domains. Copy your tracking domain (the custom domain you’ve CNAMEd to track.voluum.com).Do not use voluum.com — that won’t be associated with your workspace.
2

Enable Voluum in TagadaPay

Dashboard → Settings → Integrations → Voluum → Connect. Paste the tracking domain (no https://), save.No API key — the click_id provides the auth.
3

Make sure your offer URL forwards the Voluum click_id

Voluum’s Click ID token is {clickid}. In your campaign offer URL, append it as cid so it reaches the lander:
TagadaPay reads the cid URL parameter (also click_id as a fallback), captures it into the customer record at checkout creation, and uses that value when firing the postback.
4

Place a test order

Within ~60s of the order being paid, the conversion should appear in your Voluum Conversions report.

​
What TagadaPay Fires

Per Voluum’s official postback URL spec:
Parameter mapping: The et parameter (custom conversion types) is intentionally not fired because it requires per-account Custom Conversions setup in Voluum and would silently no-op for most merchants.

​
How TagadaPay Identifies the Click

In priority order:
  1. URL parameter cid (Voluum’s canonical name)
  2. URL parameter click_id (defensive fallback)
  3. Cookie _voluum
  4. Cookie voluum

​
Optional Settings

  • Fixed payout — if set, this number is sent as payout instead of the order’s paid amount. Useful for fixed-CPA campaigns. Leave blank to forward the actual amount paid.
There’s no conversion-type field for Voluum because the S2S endpoint distinguishes events by Voluum-side Custom Conversions, not by a postback parameter.

​
Troubleshooting

The order’s paid_amount was 0, OR a Fixed payout override is set to 0 in the TagadaPay integration form. Clear the override or check the order amount.
Voluum’s offer-level currency setting takes precedence unless currency= is in the postback. TagadaPay always sends currency now, so this should self-resolve. If not, check the Voluum offer is set to “Auto-detect from postback” rather than a fixed currency.
Most likely cause: the lander URL was missing the {clickid} token, so TagadaPay captured a stale or empty click_id. Inspect the order’s customer.metadata.queryParams in the TagadaPay CRM — cid should be a non-empty string starting with the Voluum click prefix.
