HTTP(S) and SOCKS5. - Auth + targeting are encoded in the username; password is constant. Example: `customer-USERNAME-country-us-city-new_york-sid-9f3a2b7c-ttl-600:PASSWORD@p.shifter.io:443`. - Username flags: `country`, `state`, `city`, `asn`, `sid` (session id), `ttl` (sticky seconds, only valid with `sid`). Flag order does not matter; omit `sid` for rotating IPs. Proxy management REST API (geo lookups, source-IP whitelist, proxy lists): - Residential base `https://shifter.io/api/v1/residential`, auth via `api_key` query param. - Legacy ISP plans (pinned IPs, existing customers only) base `https://shifter.io/api/v1/static-residential/{membership}`, auth via `api_token` query param. - Legacy base `https://shifter.io/api/v1/backconnect`, auth via `api_token` query param. - Keys/tokens are created in the panel under Account → API Keys / API Tokens.

[Datacenter Proxy](https://shifter.io/glossary/datacenter-proxy): A datacenter proxy is a proxy server whose IP address comes from a cloud or hosting provider, rather than an Internet Service Provider serving real consumer households. - [ISP Proxy](https://shifter.io/glossary/isp-proxy): An ISP proxy is a residential proxy whose IP address is registered to a real Internet Service Provider and served from managed infrastructure, so it carries residential trust while staying tied to one ISP and location. - [Mobile Proxy](https://shifter.io/glossary/mobile-proxy): A mobile proxy is a proxy server that routes your traffic through an IP address assigned by a mobile carrier (3G, 4G, or 5G) to a real smartphone or tablet, carrying the highest trust score with anti-bot systems. - [SOCKS5 Proxy](https://shifter.io/glossary/socks5-proxy): A SOCKS5 proxy is a proxy server that uses the SOCKS5 protocol to forward arbitrary TCP and UDP traffic between a client and a destination, without parsing or modifying the application-layer payload. - [Rotating Proxy](https://shifter.io/glossary/rotating-proxy): A rotating proxy is a proxy service that automatically assigns a different IP address to each request (or at fixed time intervals) by drawing from a pool of available IPs. - [IP Rotation](https://shifter.io/glossary/ip-rotation): IP rotation is the practice of switching the source IP address of outgoing requests on a defined cadence (per request, per time window, or per session) to distribute traffic across many IPs and avoid per-IP rate limits. - [Sticky Session](https://shifter.io/glossary/sticky-session): A sticky session is a proxy configuration that pins the same exit IP to a client for a defined window or for the lifetime of a session ID, instead of rotating to a new IP per request. - [Geo-Targeting](https://shifter.io/glossary/geo-targeting): Geo-targeting in proxy services is the ability to choose the geographic location of your exit IP — by country, region, state, city, or ASN — so that destination sites see your traffic as originating from that specific market. - [IP Pool](https://shifter.io/glossary/ip-pool): An IP pool is the collection of IP addresses a proxy provider can assign as exit IPs for customer traffic, typically spanning many subnets, ASNs, and geographies. - [Proxy Server](https://shifter.io/glossary/proxy-server): A proxy server is an intermediary system that sits between a client and a destination server, forwarding requests on behalf of the client and returning the destination's responses, typically to mask the client's IP, control access, or apply policy. - [CAPTCHA](https://shifter.io/glossary/captcha): A CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) is a challenge-response system websites use to distinguish human visitors from automated bots, typically by asking the visitor to solve a puzzle that's easy for humans but difficult for software. - [Browser Fingerprinting](https://shifter.io/glossary/browser-fingerprinting): Browser fingerprinting is a technique websites use to identify and track visitors by collecting a set of attributes from the browser (User-Agent, screen size, fonts, plugins, canvas hash, WebGL signatures, etc.) and combining them into a unique signature. - [TLS Fingerprint](https://shifter.io/glossary/tls-fingerprint): A TLS fingerprint is a hash derived from the specific structure of a client's TLS handshake (cipher list, extensions, ALPN values, GREASE bytes, etc.) that identifies the underlying HTTP client, browser, or library before any application-layer data is exchanged. - [Headless Browser](https://shifter.io/glossary/headless-browser): A headless browser is a real web browser running without a graphical user interface, controlled programmatically through APIs like Chrome DevTools Protocol or WebDriver, used for automated testing, scraping, and rendering JavaScript-heavy pages. - [User Agent](https://shifter.io/glossary/user-agent): A User-Agent is an HTTP request header that identifies the client software making the request — typically including browser name, version, OS, and rendering engine — like 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.0.0 Safari/537.36'. - [Web Scraping](https://shifter.io/glossary/web-scraping): Web scraping is the automated extraction of structured data from websites using HTTP requests, browser automation, or APIs, typically for use in analytics, monitoring, research, or downstream applications. - [SERP Scraping](https://shifter.io/glossary/serp-scraping): SERP scraping is the practice of programmatically extracting search engine results page (SERP) data — organic listings, ads, snippets, knowledge panels, local packs — from Google, Bing, Yandex, or other search engines, typically for SEO monitoring, ad-spend analysis, or rank tracking. - [Price Monitoring](https://shifter.io/glossary/price-monitoring): Price monitoring is the systematic, often automated tracking of product prices across competitor websites and marketplaces, used to inform dynamic pricing, MAP enforcement, competitive intelligence, and category analytics. - [Ad Verification](https://shifter.io/glossary/ad-verification): Ad verification is the practice of programmatically auditing where, when, and how digital ads actually appear — checking placement, viewability, brand-safety context, geo-targeting accuracy, and fraud signals — usually by visiting publisher pages from real consumer IPs and capturing what the page renders. - [Brand Protection](https://shifter.io/glossary/brand-protection): Brand protection is the systematic monitoring of online channels — marketplaces, social media, search results, paid ads, and the open web — to detect counterfeit listings, trademark abuse, impersonator accounts, and unauthorized resellers, then enforce against them. - [HTTP Proxy](https://shifter.io/glossary/http-proxy): An HTTP proxy is a proxy server that understands and forwards HTTP (and via the CONNECT method, HTTPS) traffic, operating at the application layer and able to inspect, modify, or cache request and response data for plain HTTP. - [ASN](https://shifter.io/glossary/asn): An ASN (Autonomous System Number) is a globally unique identifier assigned to a network operator (ISP, hosting provider, enterprise) by IANA, used in BGP routing to define which IP ranges that operator announces to the internet. - [Rate Limiting](https://shifter.io/glossary/rate-limiting): Rate limiting is a server-side defense that caps how many requests a single client (identified by IP, account, or session) can make in a given time window, used to protect infrastructure, prevent abuse, and ensure fair resource usage. - [robots.txt](https://shifter.io/glossary/robots-txt): robots.txt is a plain-text file at the root of a website (e.g. example.com/robots.txt) that tells web crawlers which URLs the site owner does or doesn't want them to access, following the Robots Exclusion Protocol. - [Sneaker Bot](https://shifter.io/glossary/sneaker-bot): A sneaker bot is automated software designed to purchase limited-release sneakers (or other limited-stock items) the moment they go on sale, by completing checkout faster than a human can — typically requires fast residential or ISP proxies to avoid per-IP purchase limits. ## Recent blog posts -
