How To: Implement Marketplace Credits (API)

This page is for advanced / cryptocurrency-native companies. If that’s not you, head back to the Quickstart for the standard flows.

Summary

Merchants can follow this guide to learn how to implement a Credits purchase flow on Coinflow’s Marketplace so that end-users can purchase credits, then spend those credits towards purchases with sellers. Upon spending credits, Sellers receive their earnings in their seller balance and can withdraw at any time.

Note: Coinflow’s marketplace credits run on regulated stablecoin rails under the hood, which is why some API responses return a wallet address. You don’t need any blockchain knowledge to integrate — treat the wallet field as an opaque account identifier for the payer’s credits balance.

Setup

Resources

Getting Started

  • This will generate a link which sellers can use to register themselves as a seller under the marketplace.
curl --request POST \
     --url https://api-sandbox.coinflow.cash/api/marketplace/link/seller/registration \
     --header 'Authorization: YOUR_API-KEY_HERE' \
     --header 'accept: application/json' \
     --header 'content-type: application/json' \
     --data '
{
  "email": "sellerEmailAddress@email.com", // the seller email address
  "sellerId": "seller1", // the seller id on your platform
  "country": "us", // the seller's location
  "redirectUrl": "https://www.mywebsite.com/" // url to redirect the seller to upon registration completion
}
'
  • This will generate a link which sellers can use to login to their seller dashboard to view purchases, customers, withdraw their funds, view withdraw history.
curl --request POST \
     --url https://api-sandbox.coinflow.cash/api/marketplace/link/seller/login \
     --header 'Authorization: YOUR_API-KEY_HERE' \
     --header 'accept: application/json' \
     --header 'content-type: application/json' \
     --data '
{
  "email": "sellerEmailAddress@gmail.com" //you can optionally pass the seller id instead of email eg: {"sellerId": "seller1"}
}
'

3.Create a credits account for the payer

In order to purchase credits, payers need a credits account, which holds their balance. Calling this endpoint provisions one for them based on their email. The endpoint returns a wallet address — treat this as the credits-account identifier, not as a user-visible crypto wallet.

Request
$curl --location 'https://api-sandbox.coinflow.cash/api/marketplace/wallet' \
>--header 'Authorization: YOUR_API_KEY' \
>--header 'accept: application/json' \

4. Allow the payer to purchase credits

This endpoint will generate a purchase link. Marketplaces can collect their own fees for each credit purchase if they’d like. The fixedFee or percentageFee will be taken from the subtotal and be immediately sent to your marketplace’s wallet balance when the payer purchases the credits. In the example below, the marketplace will receive 5andthepayerwillreceive5 and the payer will receive 50 in credits.
