I’ve dealt with this exact ambiguity in PayPal’s onboarding docs before—let’s walk through the practical steps to get your Return URL whitelisted, since the official guidance is pretty light on details.

First, let’s recap the documentation note you referenced:

将Return URL加入白名单 如需将商家引导回您的网站，请联系您的PayPal客户经理将该URL加入白名单。若未完成此操作，商家将被重定向至账户设置页面。

Here’s how to actually act on this:

• Check if you have an assigned PayPal account manager
  If you’re a larger merchant or part of PayPal’s premium programs, you likely have a dedicated point of contact. Reach out to them directly via the email or phone they provided, and include:

  • Your PayPal business account email/ID
  • The full, exact Return URL you need whitelisted (double-check for HTTPS and typos—small mistakes here will break the redirect)
  • A quick note explaining this is for post-onboarding merchant redirection to your platform

• If you don’t have an account manager (most small-to-medium merchants)
  You’ll need to use PayPal’s merchant support channels instead:

  1. Log into your PayPal Business account
  2. Head to the Help & Support section (look for it in the top navigation bar or bottom footer)
  3. Search for keywords like "whitelist return URL for merchant onboarding" or navigate to the "Integration & Onboarding" support category
  4. Choose your preferred contact method—chat support is usually the fastest for this type of request. When connecting with an agent, share the documentation quote you have, your account details, and the specific URL you need added.

• Pro tips to speed up the process

  • Always confirm your Return URL uses https:// (PayPal blocks unsecure HTTP URLs for whitelisting)
  • If you don’t get a response within 24-48 hours, follow up with a clear reference to the documentation line you quoted—this helps support agents prioritize your request since it’s tied to official guidance
