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
How to Add LinkedIn Credentials to Sendspark
In your Dynamic Video campaign, go to the area where you add contacts. Then click the Connect Social Account button.
In the popup that appears, next to LinkedIn, click Connect and add your LinkedIn Cookie li_at value into the input field.
To find your LinkedIn Cookie li_at value, head to your LinkedIn profile and access your inspect tools:
Open LinkedIn in a Chrome Browser
Right click on the page and then select Inspect in Chrome Developer Tools
In the Dev tools, click into Application >> Cookies >> https://www.linkedin.com >> li_at
Copy your li_at value, and paste it into Sendspark.

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 20β30 videos per day when using LinkedIn profile backgrounds.
Avoid sending large batches all at once.
If videos fail or are rejected:
Wait 24β48 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.
