## <a id="section_1"></a>Page Best Practices

Consider [PMD best practices](/wcp_docs/asx1597867253394.html) in your Extend pages to avoid impacting tenant performance when you deploy the card to your tenant and configure it in the Workday entry points (such as Workday Home Page and Workday-delivered Hubs).

## <a id="section_4"></a>Extend Cards Support in the Workday Tenant

In the Workday tenant, Extend Cards are available in:

-   Workday Home Page.
-   Workday-delivered Hubs.
-   Workday Search.
-   Workday Journeys.


Extend Cards currently aren't available in:

-   Learning Hub.
-   Career Hub


## <a id="section_limits_cards"></a>Limits on Card Components (Extend Cards)

<table><thead><tr><th>Limit</th><th>Maximum Value or Recommendation</th></tr></thead><tbody><tr><td>Number of Card components per app.</td><td>3</td></tr><tr><td>Number of Card Tenant Settings components per app.</td><td>3</td></tr><tr><td>Number of non-deferred inbound endpoints per Card component.</td><td>2</td></tr></tbody></table><br/>

## <a id="section_tenantLimits_cards"></a>Tenant Limits on Extend Cards

To protect the integrity of your Home Page and tenant, Workday Home Page has these timeouts:

<table><thead><tr><th>Limit</th><th>Maximum Value</th></tr></thead><tbody><tr><td>Inbound endpoint timeout on a Card.</td><td>5 seconds</td></tr><tr><td><p>Card load timeout on the Workday Home Page.</p> <p><b>Note:</b> If the Card load reaches the timeout limit, the Home Page doesn't display the card.</p></td><td>15 seconds</td></tr></tbody></table><br/>

If you plan to configure your Card on the Workday Home Page, we strongly suggest you test the response time of your endpoints prior to building the Card.

All of these limits are enforced in the tenant during configuration.

<table><thead><tr><th>Limit</th><th>Maximum Value</th></tr></thead><tbody><tr><td>Extend Cards on Home Page across the tenant (regardless of Security group).</td><td>4</td></tr><tr><td>Extend Cards per Hub.</td><td>4</td></tr><tr><td>Extend Card per Custom Search Result.</td><td>1</td></tr><tr><td>Extend Card per Journey Step.</td><td>1</td></tr></tbody></table><br/>

<b>Note:</b> You can deploy a single Extend Card to your tenant and configure it on multiple entry points in Workday.
