How to Use Decodo for Proxy Setup

Anti-bot systems on the internet today are far smarter than they were five years ago. Cloudflare and Akamai, the two largest site security providers, can now immediately block data center IPs on almost all popular targets, according to notes from TrustMyIP. 

As a result, anyone who needs to collect data from the web—market research, price monitoring, or SEO work—inevitably has to switch to residential proxies. Decodo, a proxy service rebranded from Smartproxy, is one of the names that often appears in recommendations because of its combination of price and performance. 

The problem is, for first-time users, how to use Decodo to set up a proxy often feels confusing because of the many technical terms. This article summarizes how to set up Decodo from scratch: create an account, choose a plan, until the first connection succeeds through a real household IP.

Key Takeaways

• Setup starts with a free account, then choose a residential plan or try it first through a 3-day/100MB trial.
• Authentication can be via username-password or IP whitelist (IPv4 only, without an active VPN when adding it).
• The proxy endpoint is configured through three main parameters—location, session type, and protocol—before being installed in a browser or scraping tool.

Why Are Residential Proxies Like Decodo Increasingly Needed?

A residential proxy is an intermediary server that forwards traffic through an IP address assigned by an Internet Service Provider to a real household device. 

Because the IP comes from a real home internet connection, the target site sees the traffic as a regular user, not an automated bot—very different from data center proxies that are easily detected and blocked.

Decodo claims to manage more than 115 million IPs from ethical sources in 195+ locations, with a 99.92% success rate and an average response time of under 0.5 seconds. 

This claim is also confirmed by independent testing from Proxyway, which recorded a 99.92% success rate and 0.53-second response time in their latest benchmark—competing closely with major players such as Oxylabs.

If you are already used to processing data from the internet for research or trading needs, the next step is usually where the research results are executed. 

For those interested in diversifying online activity into digital assets, registering an account on Bittime can be a safe starting point because the platform is already OJK-licensed.

How to Use Decodo to Set Up a Proxy: Account to Authentication

Here are the core stages:

1. Create an account and choose a plan. Register for free on the Decodo dashboard, then choose a monthly quota-based subscription, Pay As You Go for one-off projects, or a 3-day trial with a 100MB quota if you still want to test first.
2. Authenticate via username and password. Open the Authentication tab—the first user is automatically created by the system. To add another user, click + Add user, fill in the username, and the password will be generated automatically.
3. Or authenticate via IP whitelist. Choose Whitelisted IPs, then + Add IP. Important note: only IPv4 is supported, and the IP registered must truly be your own IP—it cannot be done while connected through another proxy or VPN.
4. Set traffic limit (optional). If one account is shared with a team or several scripts, limit the quota per user through the Edit user menu so that no single party uses up the entire data allowance.

Configure Location, Session, and Protocol Before Generating an Endpoint

After the account and authentication are done, the next step is in the Proxy setup tab:

• Location. It can be left random to draw from the entire IP pool, or specified down to continent, country, city, or even state level. For United States targets specifically, targeting can be even more specific down to ZIP code.
• Session type. Sticky session keeps the same IP until the time limit expires (options of 1, 10, 30, 60 minutes, or custom)—suitable for login flows, checkout, or multi-step form filling. Rotating session changes the IP on every request—better suited for large-scale data collection, price monitoring, or SERP tracking.
• Protocol. HTTP, HTTPS, and SOCKS5 are available, just adjust them to the needs of the tool being used.

After those three parameters are set, generate endpoints (default 10 endpoints), then copy them one by one or download them all at once in CSV/TXT format to install in a browser, extension, or automation tool such as Postman and Scrapy.

Do not miss the Usage Statistics tab—this is the fastest way to make sure traffic is actually going through the proxy, not still using the original IP. If error 407 appears, it usually means the credentials are wrong or the IP has not been whitelisted; if the response still shows the original IP, check again whether the proxy settings have been applied at the tool level, not just at the operating system level.

FAQ

What is a residential proxy and how is it different from a data center proxy? 

A residential proxy uses IPs from real household connections so it looks like a regular user, while a data center proxy uses server IPs that are easier for target sites to detect and block.

How long can a sticky session in Decodo last? 

Preset options of 1, 10, 30, and 60 minutes are available, or a custom duration can be set as needed. If you need an IP that changes on every request, choose a rotating session, not sticky.

What protocols does Decodo support? 

Decodo supports HTTP, HTTPS, and SOCKS5, plus endpoint:port configuration. The protocol is selected in the Proxy setup tab before endpoints are generated.

Why does error 407 appear when using a Decodo proxy? 

This error usually means the username/password is wrong or the IP has not been registered in the whitelist. The solution is to recheck the credentials in the Authentication tab or add the current IP to the whitelist.

How can I make sure the proxy is running correctly? 

Open the Usage Statistics tab in the dashboard to see whether any upload/download traffic is recorded. If the response still shows the original IP, it means the proxy settings have not been applied at the application level being used.
