Ipasa ang imong sariling ID sa gumagamit, ID sa pitaka, ID sa transaksyon, o referensya sa pag-klik ngadto sa among tracking URL aron ang parehas nga balor mobalik kanimo sa ulahing panahon sa postback..

Alang sa mga daloy sa mobile app, pwede mo usab ipasa ang IDFA (Apple) o GAID (Google) kauban ang imong subids:

Sulod sa Configuration sa Postback, i-save ang URL nga kinahanglang dawat sa imong mga pahibalo sa konbersyon. Sugdi sa pinakagamay nga mga macro nga imong kinahanglan gayod, unya dugangi lang og daghang uma kung gigamit na sa imong sistema.:

Kung gusto nimo ang tanan nga kasamtangang suportado nga kanonikal nga uma, ang imong Postback URL mahimong ingani:

Makapadala ang CPAlead og mga postback sa publisher padulong sa parehas nga mga endpoint nga HTTP ug HTTPS.

Start with {subid}, {lead_id}, {campaign_id}, {campaign_name}, and {payout}. In the current publisher postback flow, {virtual_currency} is typically 0.

Kini ang pangunang mga macro sa CPAlead nga imong maibutang sa imong URL. Ilisan kinig tinuud nga mga balor sa konbersyon kung ipadala na ang imong postback:

Kung ang imong endpoint naglimitar sa mosulod nga trapiko, i-whitelist ang relay IP sa CPAlead nga ipakita sa ubos aron dawaton sa imong servidor ang paghatod sa postback.

Kini nga sample nagpakita og mas ligtas nga sinugdanan alang sa custom integrasyon: beripikaha ang password, gamita ang lead_id alang sa idempotency, i-imbak ang hilaw nga payload, ug rewardi lang ang gamiton usa ra ka higayon.

 * CPAlead publisher postback example.

 * Recommended CPAlead URL:
 * https://example.com/postback/cpalead.php?subid={subid}&lead_id={lead_id}&campaign_id={campaign_id}&campaign_name={campaign_name}&payout={payout}&password={password}
 *
 * Notes:
 * - {subid} should usually be your internal user ID or click/reference ID.
 * - {lead_id} should be stored uniquely so retries do not double-credit a user.
 * - {payout} is the most reliable reward input in the current publisher flow.
 * - {virtual_currency} is currently sent as 0 in the standard publisher postback flow.
