How to Use the LinkedIn Auto Endorser

Before you start

• Awareness of LinkedIn’s safety limits:
  • You can endorse up to 10 profiles per launch.
  • For each profile, the Phantom can endorse up to 6 skills. To stay safe, spread endorsements across multiple launches during working hours.

Step 1: Choose which LinkedIn profiles to endorse

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 “Name of column containing profile URLs.”

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

Step 2: 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→ If your Chrome or Firefox version is outdated, your session cookie may expire much more quickly, and you’ll need to reconnect often.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 3: Choose how many profiles and skills to endorse per launch

Set the behavior for your endorsements:

• Profiles per launch: maximum 10.
• Skills per profile: maximum 6.
  → If you leave this field blank, the Phantom will automatically endorse 3 skills per profile.

Step 4: Enrich your leads with professional emails (optional)

You can choose to add verified professional email addresses to each LinkedIn profile.

Not every profile will return an email address. The match rate depends on the data available, so the number of verified emails may be lower than your credits used.

1. Click on the “Select your email discovery service” dropdown.
2. Choose one of the following options:
   • PhantomBuster credits (default option)
     • Each plan includes monthly email discovery credits.
     • 1 credit = 1 attempt to find and verify an email for one profile.
     • Credits reset monthly.
   • Third-party services
     • Connect your own account by entering your API key for:
       • Dropcontact.io
       • Hunter.io
       • Snov.io

Enabling email discovery means the Phantom will spend more time on each profile, since it needs to process both the message and the email lookup. This increases execution time per launch.

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 to review endorsed profiles.
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

• Forgetting to share your Google Sheet correctly (“Anyone with the link” required).
• 1st-degree only → you can only endorse the skills of your 1st-degree connections.
• Exceeding safe limits → endorsing too many profiles or skills at once can trigger LinkedIn restrictions.
• Using the wrong input type → the Phantom only accepts LinkedIn profile URLs, not searches or company pages.
• Browser not updated → outdated user agents cause cookies to expire quickly.

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

After endorsing connections, you may want to:

• LinkedIn Connections Export → get an updated list of your connections and see who you’ve already endorsed.
• LinkedIn Profile Scraper → enrich those connections with detailed profile data for better segmentation and targeting.
• LinkedIn Auto Liker → engage with their posts to strengthen visibility and maintain warm contact.
