IP Whitelisting (Optional but 推荐)
IP whitelisting adds an extra layer of security by only allowing API access from specific IP addresses. If your tax software provides their IP addresses, add them to your API key restrictions.
IP Restricted (More Secure)
Only specified IP addresses can 使用 the API key. Best for services with static IPs.
Unrestricted (Easier)
Any IP can 使用 the API key. Acceptable with read-only permissions, but less secure.
Finding Tax Software IPs
Check your tax software's documentation or support pages for their IP addresses. Most providers list them in their help center under "API setup" or "Integration" guides.
