To generate dynamic videos over LinkedIn profiles, connect your LinkedIn account in your Dynamic Video campaign by clicking Connect Social Account and pasting your LinkedIn li_at cookie value. Because LinkedIn can throttle rapid profile fetches, keep generation to 20 to 30 videos per day and avoid sending large batches all at once.

​
Key takeaways

  • Connect LinkedIn by pasting your li_at cookie value into Sendspark via the Connect Social Account button.
  • Find the li_at value in Chrome Developer Tools under Application → Cookies → linkedin.com → li_at.
  • Limit LinkedIn-background video generation to 20 to 30 videos per day to prevent temporary blocks.
  • If videos fail or are rejected, wait 24 to 48 hours and reset your cookie/session before retrying.
Sendspark makes it easy to generate dynamic videos of you speaking over LinkedIn profiles. This can save you a lot of time. Instead of manually recording thousands of videos, you can just shoot one video of yourself, and automatically place it over each of your prospects’ LinkedIn profiles by adding the LinkedIn URL in the Background URL field

LinkedIn Background Video Generation Limits

When generating videos using LinkedIn profile backgrounds, there are important limits to be aware of. LinkedIn may temporarily block requests if too many profile fetches are made in a short period of time. This can cause video generation attempts to fail or be rejected. Best practices:
  • Limit video generation to 20–30 videos per day when using LinkedIn profile backgrounds.
  • Avoid sending large batches all at once.
If videos fail or are rejected:
  • Wait 24–48 hours before attempting again.
  • After this waiting period, reset your cookie/session before retrying.
Following these guidelines helps ensure consistent video generation and prevents temporary blocks from LinkedIn. For more information, check this help article. LinkedIn profile background won’t create video
