Sandbox Usage Guide

When using the Sandbox environment, you will need an approved buyer. Use buyer ID 00000000-0000-0000-0000-000000000000 for all your requests. For example:

curl -X POST \
    -H "Authorization: Bearer {{token}}" \
    -H "Cache-Control: no-cache" \
    -H "Content-Type: application/x-www-form-urlencoded" \
    -d "{'buyerId': '00000000-0000-0000-0000-000000000000', 'transactionId': '1234', 'amount': 10000}" \
