# How to Connect LinkedIn and Sendspark
> Learn how to connect your LinkedIn account to Sendspark by adding your li_at cookie value, plus daily video generation limits and troubleshooting tips.
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.

**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.
