B2Proxy offers a simple and user-friendly API extraction method (authenticated via IP whitelisting) to help users quickly obtain and use dynamic residential proxies. Even first-time users of proxy services can easily complete the configuration. This article will guide you step-by-step on how to add a whitelisted IP in the dashboard and successfully extract dynamic residential proxies via the API, helping you quickly master the entire workflow.

​
I. Basic Setup Steps

​
1. Add IP Whitelist

Resi Api Go to “IP Whitelist”, click “Add Whitelist”, and enter the IP address of the network environment where you need to use residential proxies.
Note: API calls will be blocked for non-whitelisted IPs.

​
2. Select Proxy Location

API提取2 2 Country/Region: Choose from dropdown (e.g., US). If you wish to filter by network operator (ASN), click the “Disable ASN” toggle in the upper-right corner and switch it to “Enable ASN ”. Once opened, an ASN input field will appear; simply enter the target ASN number.

​
3. Set the Number of Proxies

Enter required number of IPs (e.g., 100).

​
4. Protocol & Format Configuration

Protocol: Default HTTP(S), optional SOCKS5. Format: Default TXT (one IP:PORT per line), optional JSON. Separator: Default line break.

​
5. Set Session Type

Rotating IP: Auto-rotates IP per request (ideal for scraping/data collection). Sticky IP: The IP remains fixed for a period of time (5 minutes by default), suits account management).
When selecting a sticky IP, choose “Yes” in the [Change IP in Advance] option to allow the system to automatically switch the IP earlier based on its actual available time.
If you choose “No,” the IP will remain unchanged during the sticky session and can only be switched after the session ends.

​
6. Select Hostname

Based on your network IP, select the nearest server. You can also manually choose other nodes.

​
7. Generate API URL

Click “Generate URL” to get a unique API URL. Resi Api1 Resi Api1

​
II. Call the API to Get Proxies

Open the API link in your browser or configure it in your tool. A correct response example would be: 1.1.1.1:8888 2.2.2.2:8888 … If the following message appears, it means the whitelist was not added correctly. Please go back to step one and check.
Rate Limit: 1 request/second.
Proxy Validity: 24 hours (default). Regenerate after expiry.
