Creating Orders as a Partner
Once a merchant has connected to your platform you hold theirmerchant_key, delivered in the store_onboarded webhook. That key is all you need: the request is byte-for-byte the same as a standard order creation.
The merchant key is what authorizes this call and what decides which store the order belongs to. You may add your
X-API-Key/X-API-Secret for attribution, but they never change the target store. See Partner Authentication.Example
Tracking the order back to your system
order_keyis echoed back to you asid_externalin webhooks. Use it to match the order to your own record.- Available payment gateways differ per merchant. Call gateway discovery with that merchant’s key rather than hardcoding
id_payment_gateway. - When the order is paid,
order_paymentis delivered to your partner webhook URL, not the merchant’s. See Partner Webhooks.
