environment.device | The user’s device type (e.g., desktop or mobile) |

playlistContext.publisherId | The publisher’s unique ID in the glomex system |
content.createdAt | Timestamp when content was selected for playback (can be used as a cache buster) |

Parameter Modifiers
You can apply modifiers to parameters using the pipe symbol (|):
| Modifier | Description |
|---|---|
urlencode | URL-encodes the parameter value (recommended for values that may contain spaces or special characters) |
booltoint | Converts boolean values to integers (true → 1, false → 0) |
defaultvalue | Provides a fallback value if the parameter is empty |
Example Implementation
https://your-ad-tag.com?cachebuster=[[content.createdAt]]&pub=[[playlistContext.publisherId]]&video=[[content.id]]&cat=[[content.category.name|urlencode]]&device=[[environment.device]]&referrer=[[environment.pageUrl|urlencode]]&gdpr_consent=[[environment.consentData.consentString|defaultvalue]]&gdpr=[[environment.consentData.gdprApplies|booltoint]]Ensure all parameter placeholders are properly formatted with double square brackets. Incorrect formatting may result in parameters not being replaced correctly.How It Works
The glomex system automatically replaces values inside double square brackets ([[parameter]]) before the URL is called. This allows for dynamic ad tag generation based on the specific content, user, and environment context.
