LinkedIn Network Booster

Add profiles to your network and get in touch using a personalized message

Table of Contents

You have to grow your LinkedIn network for 3 reasons

  1. LinkedIn is a highly competitive network. Get higher in search results by increasing your 1st and 2nd degree connection network.

  2. Reaching out to someone you don’t know on LinkedIn is really restricted. Grow your network and maximize your chances to have acquaintances with your target.

  3. You want to get attention and be visible? More connections = wider reach and larger audience (Yeaaah size does matter sometimes…)

Bonus: It looks really cool to have a lot of connections!

Our solution: Add into your account a list of LinkedIn profiles

Starting from a Google spreadsheet filled with a list of LinkedIn profiles, Phantombuster will send automatically, in addition to a private message, an invitation to all those profiles.

What will you need? ⚙️

  • Session cookie: Your session cookie from LinkedIn.
  • Spreadsheet URL: The link of a Google Spreadsheet (or CSV) with LinkedIn profile URLs in it.
  • Number of adds per launch: How many (between 1 and 10) invites to send per launch
  • Only second circle: Do you only want to only connect with people from your 2nd circle or not.
  • Message: The message you want to send.

(You already have all that? Click straight away on "Use this API")

How long does that take to set up this amazing hack?

It takes 5 minutes and 20 seconds (we like to do things precisely). 🕒

What you need to do.

1. Create an account on 💻

If you haven't already, create a FREE account on Phantombuster. Our service will browse the web for you. It’s a website automator which runs in the cloud. Once done we'll follow up.

2. Use this API on your account.👌

We cooked up in our lab a script with first-class attention.
Now that you're connected to Phantombuster, Click on the following button (it will open a new tab).

3. Click on Configure me!

You'll now see the 3 configuration dots blinking. Click on them.

4. Linkedin authentication 🔑

Because the script will manipulate LinkedIn for you, it needs to be logged on your LinkedIn account. For that you just need to copy paste your session cookie in the script argument:

  • Using Chrome, go to your LinkedIn homepage and open the inspector
    → Right click anywhere on the page and select “Inspect”
    CMD+OPT+i on macOS
    F12 or CTRL+MAJ+i on Windows

  • Locate the “Application” tab

  • Select “Cookies” > “” on the left menu.

  • Locate the “li_at” cookie.

  • Copy what’s under “Value” (Double click on it then Ctrl+C) and paste it into your script Argument)

// How to access your cookies with Firefox and Safari//

5. Add a Google Spreadsheet 📑

Below your session cookie you’ll find Spreadsheet URL.

Add in the Spreadsheet URL textbox the link of a Google spreadsheet with this same format (only column A is mandatory) (Share option must be OPEN):

Your spreadsheet should contain a list of profile URLs to add (one link per row).

You can also specify the name of the column that contains the profile links. Simply enter the column name in the next text field.

6. Add a private personalized message 🆕 💬

Below the column name you'll find the message configuration. This step isn’t mandatory but highly recommended.

In the message textbox you can write a private note (Total: 280 characters MAX) which will be sent to the profile included in your Google spreadsheet list in addition to the invitation to join your network.

#firstName# will be replaced in your message by the first name of the person you’re adding

Click on 💾 Save

Click on Launch & Enjoy!

It’s done! All that is left to do is to click on "launch" to try your script!

This will launch the bot and, if you didn't already change the spreadsheet URL, send Phantombuster's team LinkedIn connection requests.

⚙️️Repetition setup ⚙️

Now that your bot is ready, you just have to customize it to make it work repetitively.

Every time the bot is launched, it will send 10 connection requests and stop.

To do so, simply hit the “Settings” button to define when your bot is launched.

Follow this GIF example to run it 20 times per day:

The bot will be executed only if the time corresponds to all the criteria.

Now that this is set, click 💾 Save at the bottom of the page.

There you go, you only have to wait for connections to be made for you!


Please be aware that this API, like most of our LinkedIn APIs, will manipulate your own account on your behalf. Like Uncle Ben once said, "With great power comes great responsibility."

We have noticed that adding more than 80 connections per day will almost always result in LinkedIn invalidating your session cookie (that is, logging you out). We recommend no more than 6 launches per day of 10 connection requests for this reason.

Having a LinkedIn Premium subscription might raise this limit. Please see these official LinkedIn help pages: Commercial Use Limit and Finding People on LinkedIn.


Like all APIs on Phantombuster, this API comes with an HTTP endpoint. Launch it from your computer, app or server with a simple HTTP request and get its result as JSON. Click Use this API above to create your new endpoint.

Clone this API

The script below is all that's required to make the API work. If you're a developer, click the button to clone the code into a new Custom API Agent in your Phantombuster account. This operation will allow you to customize the API to your exact needs. This will also create a custom HTTP endpoint.
