# DeepLink - FAQ - Configuring Tracking Links

## Tracking Link Structure and Parameters

<AccordionGroup>
  <Accordion title="Is there a limit to the number of characters I can enter as a parameter value?">
    It depends on the type of tracking link. Tracking links for integrated channels have no character limit per parameter. Tracking links for custom channels allow up to 128 characters per parameter.
  </Accordion>

  <Accordion title="Are there restrictions on the characters I can enter in campaign parameter values?">
    Yes. You can only use letters, numbers, and the special characters `.` `-` `_`
  </Accordion>

  <Accordion title="When I append parameters to the short link, are they also added to the long link?">
    Yes. However, appending a campaign parameter has no effect: the campaign parameter value added to the original link through the short link isn't used anywhere, such as in reports.

    * Short link: `https://abr.ge/ouocog`
    * Long link: `https://abr.ge/@your_app/channel?ad_creative=Jeans_Clothes&ad_group=2030_female&campaign=Summer_Sales&og_tag_id=103833519`

    If you append the campaign parameter `campaign` and a custom parameter `added_params` to the short link, the same parameters are added to the long link. The appended `campaign=Spring_Sales` isn't used anywhere, and the original value `Summer_Sales` is used instead.
  </Accordion>
</AccordionGroup>

## Tracking Link Management

<AccordionGroup>
  <Accordion title="Can I delete tracking links in [Link Management]?">
    Yes. However, a tracking link deleted in **\[Link Management]** keeps working normally; it's removed from the **\[Link Management]** list only.
  </Accordion>

  <Accordion title="Why does the tracking link still redirect to the old path after I edit it?">
    Airbridge caches the previous path, so it can take up to 10 minutes for the edited path to apply. Check again after about 10 minutes.
  </Accordion>
</AccordionGroup>

## Social Share Preview

<AccordionGroup>
  <Accordion title="My edits to the thumbnail, title, and description of the social share preview are not reflected in the tracking links I share on social media.">
    The amount of time it takes for the edits to the social share preview to be reflected in the tracking links varies by social media.

    If your edits are not reflected even after a sufficient amount of time, use the sharing debugger provided by each social media to debug any issues with the Open Graph tags. If the problem still persists, contact each social media.

    * [Meta for Developers Sharing Debugger](https://developers.facebook.com/tools/debug/?locale=en)
  </Accordion>

  <Accordion title="If I change the deep link path or the redirection path of a tracking link, do I need to modify the QR code as well?">
    No. The QR code can still be used because there is no change in the tracking link itself.

    However, you will need to update the QR code if you have modified the campaign parameters, such as the channel, campaign, ad group, or ad creative.
