Tracking referral link activity and conversions via subIDs

  • Updated

SubID Overview

SubIDs are alphanumeric strings you can add to the end of your links allowing for advanced affiliate tracking. Using subIDs you can understand various performance metrics to optimize your promotions.

You can add one or multiple subIDs to any PartnerStack link. Each subID will be captured at the time of click and attributed to earned commissions after a conversion.

Once a commission has been generated, you will be able to view in your PartnerStack dashboard which subID was used.

SubIDs may not work for all companies you are partnered with. Please reach out to if you have further questions.

Adding subIDs to links

SubIDs can be added to both your default link or your custom link if the company you partner with has custom links enabled.

  1. Log in to your PartnerStack account and navigate to your Links tab
  2. Copy your PartnerStack referral link
    • For example,
  3. Paste your link into an external text document (word, sheets, notes)
  4. Append ?sid={your_sid_here} to the end of your link
    • Adding the subID 123 would be written as ?sid=123
    • You can add multiple subIDs to a link following this format:
      • ... etc
  5. Share your full link, including the subID you have added
    • Example full link:

SubIDs must be added to your links externally to PartnerStack. If custom links are enabled for your program please ensure you are not adding the subID text in your custom link text.

Viewing subID data in your Performance tab

If the company you partner with is integrated with us in a way that supports detailed link tracking, you will see additional menu options under your Performance tab. 

In your detailed link tracking you can view more detail into your subID activity. To learn more about reviewing your program performance, view our support guide Learning more about your performance and commissions.


PartnerStack now supports postbacks. Postbacks are notifications to an external service when events occur in the PartnerStack platform, such as commission creation. Postbacks are specific to Partners.
