Networks invent their own parameter names. Your field map tells 301.st how to translate them into our canonical schema. The Edit drawer shows one row per canonical field — type the network's parameter name in the input.
click_id
- The token we sent out in the redirect's
_cid. Often the network calls it clickid, cid, sub1, or subid.
event_type
- Which kind of conversion fired. Networks usually call it
event, action, or type — and they have their own vocabulary, so see Event mapping below.
transaction_id
- Unique conversion ID on the network's side. Used for deduplication — re-firing the same postback with the same
transaction_id doesn't double-count.
gross_amount / gross_currency
- What the user paid the operator (registration fee, deposit, purchase price). Currency is usually a separate field.
payout_amount / payout_currency
- What the operator pays you for the conversion — your revenue.
external_user_id
- Optional. The user's ID inside the network — useful for cross-referencing during disputes.
Leave a row blank to skip it — the field stays null on incoming conversions. Sources created via Capture currently start with an empty field map — fill it in the Edit drawer before the source is useful.
