# Third-Party Platform Limitations

> Understand current third-party integration limitations in Sendspark to plan your video personalization workflows and avoid common issues.

Sendspark can generate videos using external sources such as **LinkedIn profiles and websites**. However, LinkedIn and websites have different access requirements and limitations.

## LinkedIn Profile Backgrounds

LinkedIn applies stricter controls to automated requests. Sending too many requests in a short period can trigger temporary restrictions, which 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 a **LinkedIn-related failure**:

* Wait **24–48 hours** before retrying
* Reset your LinkedIn session cookies before trying again [**(click here to check the required steps)**](https://help.sendspark.com/linkedin-profile-background-won-t-create-video)

## Website Backgrounds

Website backgrounds work differently from LinkedIn profile backgrounds.

### Public Websites

If a website is **publicly accessible**, there should generally be no access limitation specific to Sendspark.

There is **no wait time for public websites**. If a public website is accessible, Sendspark should be able to access it.

### Private or Restricted Websites

If a website is **private, requires a login, or otherwise restricts access**, Sendspark may be unable to access the content needed to generate the background.

In these cases, the limitation comes from the website's access restrictions.

## Key Takeaway

LinkedIn and websites have different limitations:

* **LinkedIn:** Temporary restrictions may occur due to automated requests or high usage. Wait **24–48 hours** and reset your LinkedIn session cookies before retrying.
* **Public websites:** There is **no wait time**. Publicly accessible websites should generally be accessible to Sendspark.
* **Private or restricted websites:** Access is limited to what Sendspark can access publicly. If the content requires authentication or is otherwise restricted, Sendspark may not be able to use it.

## Frequently asked questions

<AccordionGroup>
  <Accordion title="Why did my video fail to generate?">
    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.
  </Accordion>

  <Accordion title="How many LinkedIn videos can I generate per day?">
    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.
  </Accordion>

  <Accordion title="What should I do after repeated failures?">
    Wait 24–48 hours before retrying, and reset your session (cookies) before starting again.
  </Accordion>

  <Accordion title="Can Sendspark override these third-party restrictions?">
    No. Sendspark continuously optimizes its integrations but cannot override the restrictions or policies of external platforms like websites and LinkedIn.
