When integrating with Zinc, you have two options for paying for purchases:

​
1. Bring Your Own Account

You provide your own retailer account credentials (e.g., Amazon username and password) and Zinc will place orders on your behalf using your account. Benefits:
  • Full control over your orders and account.
  • Use your own payment methods (e.g., credit cards for cashback, points, etc.).
  • Access to your retailer’s loyalty programs and purchase history.
Considerations:
  • You are responsible for maintaining your retailer accounts.
  • Retailers may occasionally lock or restrict accounts due to high activity or policy changes.

​
2. Zinc Managed Accounts (ZMA)

Let Zinc handle everything. With ZMA, you fund a balance with Zinc (via PayPal or wire transfer), and Zinc places orders using its own managed retailer accounts. Benefits:
  • No need to create or manage your own retailer accounts.
  • Zinc handles account maintenance, order placement, and fulfillment.
  • Reduced risk of account shutdowns or interruptions.
How it works:
  1. Fund your account:
    Add funds to your Zinc balance via PayPal or wire transfer.
    • Check your balance: 
      curl "https://api.zinc.io/v1/addax/balance" -u <client_token>:
    • View transactions: 
      curl "https://api.zinc.io/v1/addax/transactions?count=100&offset=0" -u <client_token>:
    • Contact sales@zinc.io to set up funding options.
  2. Place an order:
    • Add "addax": true to your order request body.
    • Do not include retailer_credentials, payment_method, or billing_address.
    • All other order features work as usual.
  3. Order processing:
    • Orders are queued until a suitable fulfillment account is available.
    • If an order cannot be fulfilled in time, you’ll receive a zma_temporarily_overloaded error.
  4. Cases & support:
    • If an order is cancelled, returned, or needs follow-up, Zinc will open a “case” for you.
    • You can check or update case status via the API.
Considerations:
  • ZMA is currently available for Amazon.com only.
  • You’ll still be billed the normal ordering fee at the end of the month.
