Inventory Partner Implementation Notes:

  • When copying and pasting Servo ad tags provided in an Excel document, please copy and paste the tag from within the cell. Copying and pasting the whole cell will result in double quotation marks, which will cause errors.
  • Each tag should be implemented in its entirety. Only scheduling portions of the Servo ad tag will result in potential loss of functionality and reporting discrepancies.
  • JS tags will be generated as secure-only or as environment aware, where they will serve as secure when implemented into secure environments. Protocols within the tag should not be adjusted.
  • It is NOT necessary to implement a cachebuster in the Servo 4th Party JavaScript creative tag.
  • $$_DESTINATION_URL_$$ should not be removed.


click: Your click redirect macro must directly prepend the Servo click macro $$_DESTINATION_URL_$$. 
ex & site fields: These two fields are optional. This is where you can add your Inventory Partner exchange tracking macro and/or your Inventory Partner site tracking macro.
osdevid & osoptout fields: These two fields are where you add your Device ID (IDFA/AAID/GAID) and OptOut macros. If your device ID macro will not populate a device ID when a user opts out of being tracked, your opt out macro isn't necessary.
