How to Use the LinkedIn Join Group Inviter

Before you start

• Awareness of LinkedIn’s safety limits:
  • Invite up to 80 profiles/day with a Basic account.
  • Invite up to 150/day with a Premium account.

Step 1: Provide your connections list

You can provide your profiles in three ways:

1. My Lists:
   Choose a saved LinkedIn Leads list you’ve already created in PhantomBuster.
2. A URL:
   • Paste a single LinkedIn profile URL.
   • Provide a Google Sheet with LinkedIn profile URLs (make sure it’s shared with “Anyone with the link”).

   • Upload a CSV file with LinkedIn profile URLs (make sure it’s publicly accessible, and note that CSV upload is only available on paid plans).

     → If you’re using a spreadsheet, the Phantom defaults to the first column (A). To use a different column, enter the column’s header name in the field “Column where LinkedIn profile URLs are stored.”

3. My Phantoms:
   Use results from another Phantom as input (e.g. LinkedIn Search Export or LinkedIn Profile Scraper results).

Then, specify the type of connection input (optional):
Choose how your connections are represented in your file:

• LinkedIn Profile URLs → the most reliable option.
• Full name (from official extract) → match by full name.
• First name & last name (from official extract) → match by separate name fields.

Step 2: Provide the group URL

Enter the URL of the LinkedIn Group you want your connections to join.

• It must be a single LinkedIn Group URL.
• You must already be a member of the group.

Step 3: Connect your LinkedIn account

To let the Phantom act on your behalf:

1. Install the PhantomBuster browser extension and connect your LinkedIn session in one click.
2. If you’re not using Chrome or Firefox, you can retrieve your session cookie manually (see our cookie guide).

Check your browser user agent
Make sure your browser is up to date before connecting your account. 
→ If your Chrome or Firefox version is outdated, your session cookie may expire much more quickly, and you’ll need to reconnect often.

Step 4: Configure how many invitations to send

Set how many invitations the Phantom should process per run:

• Number of profiles to invite per launch (optional):
  • Default = 10 per run.
  • Maximum = 100 per run.
  • Example: If you want to invite 50 profiles, set 10 per run and schedule 5 launches throughout the day.

Stay within daily limits (80–150 depending on your account type) and space runs naturally to avoid LinkedIn restrictions.

Step 5: Select launch frequency

Choose how often the Phantom should run:

1. Launch manually: Start the Phantom yourself whenever you need.
2. Launch once at a specific time: schedule a one-time run at a set date and time.
3. Launch repeatedly: schedule regular runs (e.g. once per day, several times during working hours).
4. Launch after another Phantom: chain automations together so this Phantom starts right after another finishes.
5. Advanced scheduling: customize the exact minutes, hours, days, or months when the Phantom should run.

→ For a complete walkthrough of scheduling options, see our guide to scheduling Phantoms automatically.

Step 6 (Optional): Advanced settings

Advanced settings are available if you want to fine-tune how your Phantom runs, but by default they’re already optimized for most use cases.

We recommend leaving them as they are unless a guide specifically instructs you to change something.

→ For a detailed overview of all advanced options (like execution limits, retries, email notifications, proxies, webhooks, and file management), see our Advanced settings guide.

Launch and results

When you’re ready:

1. Click Launch to start your Phantom.
2. Once it finishes, open the Results tab in the Phantom console to see the data collected.
3. Download your results as a CSV or JSON file.

→ To learn how to export your data to Google Sheets, integrate with other tools, or reuse it in more automations, check our Access and Export your Phantom Results guide.

Export and input limits on the Free plan
If you’re on the Free plan or Free trial, some features are limited:
- CSV exports include only the first 10 rows of results.
- CSV download links (for dynamic viewing in Google Sheets or integrations) are not available.
- JSON exports are not available.
- CSV upload as an input method is not supported.
To unlock all features, you’ll need to upgrade to a paid plan.

Tips and troubleshooting

Common pitfalls

• Using a private Google Sheet → make sure it’s shared with “Anyone with the link.”
• Not being a member of the group you’re inviting others to join.
• Exceeding safe daily invitation limits.
• Mixing non-profile URLs (e.g., company pages or search URLs) into your list.

If you run into issues

• Check how to troubleshoot your phantom using Logs.
• Browse the Fix Issues & Troubleshoot Errors section for solutions to common problems.
• Review our Automation Rate Limits by Platform guide.
• Check our Best Practices for Social Media Automation guide.

Suggested automations

To maximize group growth:

• LinkedIn Search Export → find new prospects, then invite them to join your group.
• LinkedIn Group Member Message Sender → engage with group members individually after they join.
