AUTHENTICATION_FAILURE。贝宝付款错误 api。 Python

Question

我想为客户提供付款方式。您需要收款并检查客户是否已付款。我成功创建了付款表单，但出现错误。

import requests

resp = requests.post(
    url="https://api-m.sandbox.paypal.com/v1/oauth2/token",
    auth=("XXXX", "XXXXX"),
    data=b"grant_type=client_credentials",
    headers={
        "Accept": "application/json",
        "Accept-Language": "en_US",
    },
)
resp.raise_for_status()

access_token = resp.json()['access_token']
print(access_token)

print(r.status_code, r.json())

作为响应，我得到了代码 201。创建的付款和链接的详细信息。如果我没理解错，授权错误。

当我点击链接时，我看到了这个：

{"name":"AUTHENTICATION_FAILURE","message":"Authentication failed due to invalid authentication credentials or a missing Authorization header.","links":[{"href":"https://developer.paypal.com/docs/api/overview/#error","rel":"information_link"}]}

我设法得到 access_token。而且我确信其他标记是正确的。告诉我如何解决这个问题。我一定是在某个地方犯了错误。预先感谢您的帮助。

Answer 1

您似乎“点击”了错误的 link，rel:execute 的 href，而不是 rel:approve 的 href。

rel:execute link 用于在付款人批准付款并重定向回 return_url 您的网站应该显示其最后的确认步骤。在您执行最终执行 API 确认调用之前，不会创建任何交易（销售）。

以上所有术语均适用于已弃用的 v1/payments API，无论如何您都不应该将其用于任何用途。对于这样的结帐，请改用当前的 v2/checkout/orders API。
