Apna user ID, wallet ID, transaction ID, ya click reference hamari tracking URL mein pass karo taaki wahi value baad mein postback mein tumhe wapas mil jaaye..

Mobile app flows ke liye, tum IDFA (Apple) ya GAID (Google) apne subids ke saath bhi pass kar sakte ho:

Postback Configuration ke andar, woh URL save karo jo tumhari conversion notifications receive karega. Pehle un minimum macros se shuru karo jinhe tum waaqai zaroorat ho, phir sirf tab aur fields add karo jab tumhara system unhe use karta ho.:

Agar tum har abhi supported canonical field chahte ho, to tumhari postback URL is tarah dikh sakti hai:

CPAlead publisher postbacks ko HTTP aur HTTPS dono endpoints par bhej sakta hai.

Start with {subid}, {lead_id}, {campaign_id}, {campaign_name}, and {payout}. For event-based offers, add {event_key}, {event_name}, and {event_payout} only if your system needs event details. In the current publisher postback flow, {virtual_currency} is typically 0.

Ye CPAlead ke pramukh macros hain jinhe tum apni URL mein lagaa sakte ho. Jab tumhara postback bheja jaayega to ye live conversion values se badal jaayenge:

Agar tumhara endpoint andar aane waale traffic par paabandi lagata hai, to neeche dikhaye gaye CPAlead relay IP ko whitelist karo taaki tumhara server postback delivery swikar kar le.

Ye namuna ek custom integration ke liye zyada mehfooz shuruati nuqta dikhata hai: password verify karo, idempotency ke liye lead_id ka upyog karo, raw payload store karo, aur user ko sirf ek baar reward karo.

/*
 * 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.
