How Do You Bulk Import Proxies in Multilogin and GoLogin?

What Happens When You Paste a Proxy List Into Multilogin or GoLogin?

Both tools import proxies as pasted text, not a file drop. For bulk proxy import multilogin gologin, the short answer: Multilogin takes IP:port:login:password (or plain IP:port for allowlisted proxies), caps one paste at 25 entries and documents no file-based import. GoLogin accepts three named formats in a single bulk paste on its Proxies page and tests every line on save.

Step 1: Turn Your Provider Export Into a Format Both Apps Parse

Providers export whatever their dashboard produces: host:port:user:pass, credentials inside a URL, or a spreadsheet with a header row. Neither app reads those as-is. The bulk proxy import multilogin gologin workflow starts with two decisions — field order and authentication mode — and both decide whether your paste lands on the first attempt.

Password authentication vs IP allowlisting

In password mode every request carries a username and password, so each line keeps four parts: IP:port:login:password in Multilogin and the same order in GoLogin. In IP-allowlist mode the provider trusts your public IP instead of credentials, and the line shrinks to IP:port. That shorter line is easier to handle but tied to one network: a VPN switch or a new router can turn a whole list red at once.

GoLogin adds a wrinkle. Its proxy checker runs from GoLogin’s own infrastructure, not from your machine, so an allowlisted proxy can fail the built-in check while working from your browser — GoLogin’s support docs list IP allowlisting as a cause of failed checks. Test locally before you rewrite a list that is fine.

Normalise the field order

Build one plain-text file: one proxy per line, no header, no blank rows. Three clean-up jobs cover most exports — strip spaces after commas, drop a trailing :name label when the target is Multilogin (its parser expects four fields), and keep a scheme prefix only where the tool asks for one.

CSV is the format people expect and the one both apps handle least directly. Multilogin documents no file-based proxy import, and GoLogin’s documented route is a paste field. Turning a spreadsheet column into newline-separated lines takes one formula and saves an afternoon of retyping.

Step 2: Bulk Import Into Multilogin in Batches of 25

Multilogin is built around pasted lists and API calls, not file uploads. The steps below match Multilogin X; Multilogin 6, the previous desktop app that still runs on older macOS versions such as Monterey and Big Sur, uses the same field order on different screens.

1. Check the plan tier your workflow needs. Scripting through the API starts at Pro 10, and the proxy template manager with a One proxy format option starts at Pro 50. Those gates shift between releases, so confirm on your plan page before you invest in a list.
2. Open the proxy manager and use the bulk paste field. One proxy per line, no commas, no header. Mixing four-field and two-field lines in one paste is the quickest route to a “Wrong proxy data” error.
3. Paste in blocks of 25. A single paste accepts up to 25 proxies. A 300-address pool becomes twelve pastes — number the blocks in your source file so you can see which one went missing.
4. Save and read the status column. “Proxy check failed” means the endpoint is not answering, usually a dead proxy or a provider outage rather than a syntax problem.
5. Attach the proxy to a profile. Open profile settings, pick the saved proxy, save. Timezone, geolocation and WebRTC align to the exit IP automatically in both Multilogin browser cores.
6. Write the pairing down. Profile name, proxy host and port, provider account, and the client or storefront it belongs to. You will want that record the first time a proxy expires.

Multilogin’s error messages are specific enough to diagnose: “Proxy check failed” for an offline proxy, “Wrong proxy data” for spent traffic or a dead IP, and ERR_SOCKS_CONNECTION_FAILED for a misconfigured or offline SOCKS5 endpoint. Each one is covered in this walkthrough to fix Multilogin proxy errors.

Multilogin’s own residential and mobile pool

Some profiles never need a provider list. Multilogin’s built-in pool covers 30M+ residential and mobile IPs and is configured per profile under Proxy > Multilogin, where you choose Mobile or Residential and set rotation to keep the IP (an average of 24 hours), a custom interval, or manual. Keep-IP suits a working session; a 24-hour average still means the exit address can move during an afternoon, so pick manual or a custom interval for a long logged-in task.

Step 3: Bulk Import Into GoLogin From the Proxies Page

GoLogin’s import is shorter and noisier: fewer screens, but every saved line is tested immediately, so a bad paste shows up in seconds.

1. Go to Proxies, then Import proxies, then Paste proxies. That is the documented bulk route and it takes a whole list at once.
2. Pick the line format per proxy. GoLogin accepts 192.168.0.1:8000:login:password, http://192.168.0.1:8000:login:password:name and socks5://login:[email protected]:8000:name. The trailing name is a label you choose — use the client or the country to keep the list readable.
3. Save and watch the indicator. Each proxy is checked the moment it saves and marked green or red. Clear the reds before assigning anything to a profile.
4. Use the Location column for single profiles. On the All profiles page you can paste a proxy straight into a profile’s Location cell — handy for one, impractical for fifty.
5. Re-test inside the profile. Load an IP lookup page in the open profile. The exit IP shown inside the browser is the one that matters, not the one in the proxy list.

A green mark only proves the proxy answered from GoLogin’s servers, which matters when your provider authenticates by IP allowlist. If you are working through these screens for the first time, this guide to set up a GoLogin proxy follows the same flow field by field.

Step 4: Assign One Proxy per Profile and Keep a Map

Import puts addresses into the app; assignment is where mistakes happen. Give each profile its own proxy where you have enough addresses, and record the pairing: host and port, profile name, platform, account owner. Providers recycle IPs, so a returned address deserves a fresh check before it lands on another profile.

Platform limits sit outside all of this. Where a platform caps how many accounts you may run, use its official route — Amazon approves additional seller accounts through its own process, and agencies on Meta add client accounts through Business Manager roles. Settle permissions first, then wire proxies for the accounts you are cleared to manage.

Keep the proxy’s country aligned with the account’s history

Timezone, locale, WebRTC and geolocation follow the exit IP automatically in Multilogin; Send.win aligns the same four signals to each profile’s proxy. Convenient until you give a German address to a profile that has always operated from Spain: the apparent location moves, and a platform that tracks account location may ask you to verify. Complete that verification through the platform’s own process instead of swapping proxies until the prompt disappears. Tool choice does not change the discipline — a Multilogin vs GoLogin comparison only helps once both apps are configured the same way.

Sticky sessions need to outlast the task

A proxy that rotates every 10 minutes drops a logged-in session mid-task. Match the rotation window to the work: a two-hour shift answering client messages needs a sticky window longer than two hours, while a one-off check of a public page does not. With Multilogin’s built-in pool that means manual rotation or a custom interval; with a provider it usually means a sticky token in the username, such as the sessid-style parameter many dashboards document.

Step 5: Verify Every Profile After the Import

“Import finished” is not “import working”. Run this checklist on each new profile after a bulk proxy import multilogin gologin, and before anyone signs into a client account through it.

• Exit IP and country. Load an IP lookup inside the profile and compare city and country code with what you ordered.
• Timezone and WebRTC. The reported timezone should match the IP’s region, and WebRTC should not expose a different address.
• Bandwidth counter. In Multilogin an exhausted proxy shows a negative byte count — spent traffic, not a broken endpoint.
• System clock. Manual clock drift on the host breaks TLS handshakes and looks exactly like a proxy failure. Sync before you open a ticket.
• First login. Sign in once and watch for a verification prompt. Handle it through the platform, then leave that profile’s proxy alone.
• The map. Record the verified exit IP beside the profile name, so a failure a month later has a baseline to compare against.

How Do You Convert a Proxy List to JSON Without Retyping It?

Multilogin published json_proxy_list.py in October 2026: it reads a pasted block or a .txt file, splits on comma, bar, space or newline, and writes structured proxies.json for API workflows. It assumes your lines are already well formed. If you want a version that refuses bad lines and checks each proxy before you paste it, use this one.

import json
import urllib.request

RAW = """
gw.dataimpulse.com:823:user:pass
http://192.168.0.1:8000:login:password:office
socks5://login:[email protected]:8000:store-2
"""

def parse_line(line):
    line = line.strip()
    if not line:
        return None
    scheme, rest = "http", line
    if "://" in line:
        scheme, rest = line.split("://", 1)
    scheme = scheme.lower()
    user = pw = None
    if "@" in rest:
        creds, rest = rest.split("@", 1)
        user, _, pw = creds.partition(":")
    parts = rest.split(":")
    if len(parts) < 2:
        raise ValueError("No port in line: " + line)
    host, port = parts[0], int(parts[1])
    name = parts[2] if (user and len(parts) > 2) else host
    if user is None:
        if len(parts) == 4:
            user, pw = parts[2], parts[3]
        elif len(parts) == 5:
            user, pw, name = parts[2], parts[3], parts[4]
        elif len(parts) != 2:
            raise ValueError("Cannot read line: " + line)
    return {
        "name": name,
        "protocol": scheme.upper(),
        "host": host,
        "port": port,
        "username": user,
        "password": pw,
    }

def check(proxy, timeout=15):
    auth = ""
    if proxy["username"]:
        auth = "{}:{}@".format(proxy["username"], proxy["password"])
    url = "http://{}{}:{}".format(auth, proxy["host"], proxy["port"])
    opener = urllib.request.build_opener(
        urllib.request.ProxyHandler({"http": url, "https": url})
    )
    try:
        with opener.open("http://ip-api.com/json", timeout=timeout) as response:
            data = json.load(response)
        return data.get("query"), data.get("country")
    except Exception as error:
        return None, str(error)

proxies = [entry for entry in (parse_line(line) for line in RAW.splitlines()) if entry]

with open("proxies.json", "w", encoding="utf-8") as handle:
    json.dump(proxies, handle, indent=2)

for proxy in proxies:
    if proxy["protocol"].startswith("SOCKS"):
        print(proxy["name"], "socks5 - test separately with curl --socks5")
        continue
    print(proxy["name"], check(proxy))

Run it in any Python 3 environment — nothing outside the standard library. It writes proxies.json beside the script, prints one result per proxy and stops on a malformed line instead of guessing at it. HTTP and HTTPS entries are tested inside the script; SOCKS5 entries print for a separate curl --socks5 check, because the standard library does not speak SOCKS.

If you drive Multilogin through its API, note the ports: the local launcher listens on 45001, and the browser port it returns is not stable between launches. Multilogin tells you to fetch it dynamically on every start and never hardcode it, because anything that assumes a fixed port works once and then fails.

What Goes Wrong After a Bulk Import, and How to Fix Each Case

Almost every bulk proxy import multilogin gologin problem maps to a handful of causes: a dead endpoint, spent traffic, an allowlist mismatch, a port that changed with the protocol, or local software sitting in the path.

The failures that are not the proxy’s fault

Antivirus, a local firewall, a VPN client or a proxy utility such as Proxifier can intercept the connection before either app reaches the endpoint, and ISP-level blocking can do the same from outside your machine. Test the same proxy with curl on the same computer: if curl works and the app fails, the problem is local software; if curl fails too, go back to the provider with the exact host and port.

Switching protocol changes the port

Move a Multilogin profile from SOCKS5 to HTTP and the port usually changes with it. The proxy then passes a fresh check while the profile keeps failing, because the profile still holds the old port. Update the port in the profile’s proxy settings, not just in the saved proxy list.

Migration is not a proxy import

Moving profiles between tools adds steps people forget. GoLogin’s migration wizard assigns new fingerprints to imported profiles, which can trigger a verification step and a warming period before normal use. Cookies from tools the wizard does not list are imported by hand, and extensions do not transfer at all. Proxies may come across, but re-verify each one after import. If a batch will not open after a move, this guide to GoLogin launch and proxy errors separates proxy faults from profile faults.

Frequently Asked Questions

How many proxies can I paste into Multilogin at once?

25 per paste. Multilogin documents no file-based proxy import, so a larger pool goes in as batches of 25 or through the API on a plan that includes scripting. Label the batches in your source file so you can spot the one that failed.

What proxy format does GoLogin accept for bulk paste?

Three: IP:port:login:password, http://IP:port:login:password:name and socks5://login:password@IP:port:name. Paste them under Proxies > Import proxies > Paste proxies, or into a single profile’s Location cell on the All profiles page.

Is there a CSV import for Multilogin or GoLogin?

Neither documents a CSV proxy import. Multilogin is paste-and-API based, and GoLogin’s documented route is a paste field that tests each line on save. Convert your spreadsheet to newline-separated lines first, with no header row.

How do I assign a different proxy to each profile?

Save the list once in the proxy manager, then pick a proxy per profile in its settings; in GoLogin you can also paste into the Location column. Keep a sheet mapping proxy, profile and account owner so no address ends up on two profiles.

Why do my proxies fail after a bulk import?

After a bulk proxy import multilogin gologin, failures usually trace to a dead endpoint, spent traffic (a negative byte count in Multilogin), an allowlisted address that changed, a port that moved with the protocol, or local software such as antivirus, a VPN or Proxifier intercepting the connection. Test one proxy with curl on the same machine to see which layer failed.

How do I convert a proxy list to JSON for Multilogin?

Multilogin’s json_proxy_list.py splits a pasted block or .txt file on comma, bar, space or newline and writes proxies.json. The parser above does the same job and refuses malformed lines. Keep the JSON as your source of truth and paste from it.

How do IP-authenticated and password-authenticated proxies differ?

Password authentication sends a username and password with every request, so the entry has four fields and works from any network. IP allowlisting trusts one public IP instead, so the entry is just IP:port — shorter, but broken the moment that address changes.

Can I migrate proxies from Multilogin to GoLogin?

Proxies can travel with a profile migration but must be re-verified afterwards. GoLogin’s wizard assigns new fingerprints, so expect a verification step and a warming period; cookies from unlisted tools are imported manually and extensions do not transfer.
