Sendspark can build videos from external sources like websites and LinkedIn profiles, but those features depend on third-party platforms Sendspark doesn’t control. Rate limits, anti-automation security, and usage restrictions can cause video generation to fail or be rejected. For LinkedIn, keep usage to 20–30 videos per day and avoid large bulk requests to prevent temporary blocks.

​
Key takeaways

  • Website and LinkedIn backgrounds rely on external platforms Sendspark can’t control.
  • Failures often come from rate limits, anti-bot security, or usage-based restrictions on the host, not from Sendspark.
  • For LinkedIn, keep usage to 20–30 videos per day and avoid large bulk requests.
  • If you hit failures, wait 24–48 hours and reset your session cookies before retrying.

Third-Party Platform Limitations (e.g., Websites, LinkedIn)

Sendspark can generate videos using content from external sources such as websites or LinkedIn profiles. While our system is designed to work reliably, these features depend on third-party platforms that we do not control. Each platform (for example, websites vs. LinkedIn) may have different rules and limitations, including:
  • Rate limits (how many requests can be made in a given time)
  • Security protections against automated requests
  • Temporary or permanent restrictions based on usage patterns
Because of this, video generation may occasionally fail or be rejected—not due to an issue within Sendspark, but because the external platform has limited or denied the request. Basically, results can’t be guaranteed; they are subject to the response you get from the host.

​
Common Scenarios

1. Website-based backgrounds
  • Some websites block automated requests or scraping activity
  • Access may be restricted based on IP, region, or security settings
  • Failures can happen unpredictably depending on the site’s configuration
2. LinkedIn profile backgrounds
  • LinkedIn applies stricter controls on automated requests
  • Sending too many requests in a short period can trigger temporary blocks
  • This may result in failed or rejected video generation attempts
Recommended limits for LinkedIn:
  • Keep usage between 20–30 videos per day
  • Avoid large bulk requests in a short timeframe
If you exceed these limits and experience failures:

Key Takeaway

Sendspark’s video generation system is fully operational, but when using external sources, performance is subject to the availability and policies of those platforms. We continuously optimize our integrations, but cannot override third-party restrictions.

​
Frequently asked questions

When using external sources, video generation can fail or be rejected because the external platform limited or denied the request, for example through rate limits or security protections against automated requests. This is not an issue within Sendspark.
Keep LinkedIn usage between 20–30 videos per day and avoid large bulk requests in a short timeframe, since LinkedIn applies stricter controls on automated requests.
Wait 24–48 hours before retrying, and reset your session (cookies) before starting again.
No. Sendspark continuously optimizes its integrations but cannot override the restrictions or policies of external platforms like websites and LinkedIn.
