PayPal

  1. 开发者账号
    https://developer.paypal.com/developer/accounts?event=createSuccess
  2. 查找商户账户密码
  3. 再登陆https://www.sandbox.paypal.com/mep/dashboard
  4. 在浏览器输入：https://www.sandbox.paypal.com/，点击登录，输入创建好的 ”商家账号“ 的邮箱和密码

API流程

Integration steps 集成步骤

  1. Required 必填 Set up your development environment
    .
    设置开发环境。
  2. Required 必填 Create PayPal payment
    . 创建PayPal付款。
  3. Required 必填 Get payment approval
    . 获得付款批准。
  4. Required 必填 Execute payment
    . 执行付款。
  5. Optional 自选 Search payment details
    . 搜索付款详细信息。

Create PayPal payment 创建PayPal付款
After you collect the payment details from the customer, specify the payment details in a /payment call.
从客户收集付款详细信息后，在 /payment 呼叫中指定付款详细信息。
In the request URI, set the .
在请求 URI 中，设置 .
In the JSON request body, set the intent to sale, the redirect URLs, the payment_method to paypal, and the transaction information in the transactions array, which contains one or more transaction objects:

在 JSON 请求正文中，在 transactions 包含一个或多个 transaction 对象的数组中设置 to、重定向 URL、 intent payment_method to paypal sale 和事务信息：

curl -v -X POST https://api-m.sandbox.paypal.com/v1/payments/payment \-H "Content-Type: application/json" \-H "Authorization: Bearer <Access-Token>" \-d '{"intent": "sale","payer": {"payment_method": "paypal"},"transactions": [{"amount": {"total": "30.11","currency": "USD","details": {"subtotal": "30.00","tax": "0.07","shipping": "0.03","handling_fee": "1.00","shipping_discount": "-1.00","insurance": "0.01"}},"description": "This is the payment transaction description.","custom": "EBAY_EMS_90048630024435","invoice_number": "48787589673","payment_options": {"allowed_payment_method": "INSTANT_FUNDING_SOURCE"},"soft_descriptor": "ECHI5786786","item_list": {"items": [{"name": "hat","description": "Brown color hat","quantity": "5","price": "3","tax": "0.01","sku": "1","currency": "USD"}, {"name": "handbag","description": "Black color hand bag","quantity": "1","price": "15","tax": "0.02","sku": "product34","currency": "USD"}],"shipping_address": {"recipient_name": "Hello World","line1": "4thFloor","line2": "unit#34","city": "SAn Jose","country_code": "US","postal_code": "95131","phone": "011862212345678","state": "CA"}}}],"note_to_payer": "Contact us for any questions on your order.","redirect_urls": {"return_url": "https://example.com","cancel_url": "https://example.com"}
}'

A successful call returns confirmation of the transaction, with the created state and a payment ID that you can use in subsequent calls:

Execute payment 支付执行完
To execute the payment after the customer’s approval, make a /payment/execute/ call. In the JSON request body, use the payerID value that was passed to your site. In the header, use the access token that you used when you created the payment.

curl -v -X POST https://api-m.sandbox.paypal.com/v1/payments/payment/PAY-34629814WL663112AKEE3AWQ/execute \-H "Content-Type: application/json" \-H "Authorization: Bearer <Access-Token>" \-d '{"payer_id": "RRCYJUTFJGZTA"
}'
The execute payment call returns a paymentobject with transaction details:{"id": "PAY-4N746561P0587231SKQQK6MY","create_time": "2014-09-22T23:22:27Z","update_time": "2014-09-22T23:31:13Z","state": "approved","intent": "sale","payer": {"payment_method": "paypal","payer_info": {"email": "npurayil-uspr-60@paypal.com","first_name": "Brian","last_name": "Robinson","payer_id": "JMKDKJ4D7DG7G","shipping_address": {"line1": "4thFloor","line2": "unit#34","city": "SAn Jose","state": "CA","postal_code": "95131","country_code": "US","phone": "011862212345678","recipient_name": "HelloWorld"}}},"transactions": [{"amount": {"total": "30.11","currency": "USD","details": {"subtotal": "30.00","tax": "0.07","shipping": "0.03","handling_fee": "1.00","insurance": "0.01","shipping_discount": "-1.00"}},"description": "This is the payment transaction description.","item_list": {"items": [{"name": "hat","sku": "1","price": "3.00","currency": "USD","quantity": "5","description": "Brown color hat","tax": "0.01"},{"name": "handbag","sku": "product34","price": "15.00","currency": "USD","quantity": "1","description": "Black color handbag","tax": "0.02"}],"shipping_address": {"recipient_name": "HelloWorld","line1": "4thFloor","line2": "unit#34","city": "SAn Jose","state": "CA","phone": "011862212345678","postal_code": "95131","country_code": "US"}},"related_resources": [{"sale": {"id": "4XP56210M0797192Y","create_time": "2014-09-22T23:22:27Z","update_time": "2014-09-22T23:31:13Z","amount": {"total": "30.11","currency": "USD"},"payment_mode": "INSTANT_TRANSFER","state": "completed","protection_eligibility": "ELIGIBLE","protection_eligibility_type": "ITEM_NOT_RECEIVED_ELIGIBLE","transaction_fee": {"value": "1.75","currency": "USD"},"parent_payment": "PAY-4N746561P0587231SKQQK6MY","links": [{"href": "https://api-m.paypal.com/v1/payments/sale/4XP56210M0797192Y","rel": "self","method": "GET"},{"href": "https://api-m.paypal.com/v1/payments/sale/4XP56210M0797192Y/refund","rel": "refund","method": "POST"},{"href": "https://api-m.paypal.com/v1/payments/payment/PAY-4N746561P0587231SKQQK6MY","rel": "parent_payment","method": "GET"}]}}]}],"links": [{"href": "https://api-m.paypal.com/v1/payments/payment/PAY-4N746561P0587231SKQQK6MY","rel": "self","method": "GET"}]
}

refund 退款

curl -v https://api-m.sandbox.paypal.com/v1/payments/sale/67D22837NN7279935/refund \-H "Content-Type: application/json" \-H "Authorization: Bearer <Access-Token>" \-d '{}'
