Dub’s powerful attribution platform lets you understand how well your links are translating to actual users and revenue dollars.

In this guide, we’ll learn how to track conversion events with Dub using server-side tracking.
The recommended way to track conversions on Dub is using server-side tracking, which is more reliable than client-side tracking.
Step 1: Enable conversion tracking for your links
Step 2: Install the Dub Analytics script
Next, you’ll need to install the Dub Analytics script.
This script detects the dub_id query parameter and storing it as a first-party cookie, which will be used to attribute subsequent conversion events to the original link.

Step 3: Install the Dub server-side SDK
Depending on which framework you’re using, you can use our native SDKs to track conversion events:
TypeScript

Go

Python

Ruby

PHP

If you’re using a framework that isn’t listed, you can use the Dub REST API to track events on the server-side:
Step 4: Track conversion events
Now comes the fun part – tracking conversion events.
Tracking lead events
The first event you’ll want to track is a lead event. This happens when a user performs an action that indicates interest in your product or service. This could be anything from:
- Signing up for an account
- Adding a product to cart
- Joining a mailing list

Our most common lead event is Sign Up, which happens when a user signs up for an account. Depending on which authentication framework you’re using, here are a few examples of how to send Sign Up lead events:
The lead event will serve as the source of truth for the customer’s identity and which link they came from. This means that all subsequent actions performed by the customer (e.g. upgrading their plan, purchasing a product) will automatically be attributed to the original link.
Tracking sale events
The second event you’ll want to send is a sale event. This happens when a user purchases your product or service. This could be anything from:
- Subscribing to a paid plan
- Usage expansion (upgrading from one plan to another)
- Purchasing a product

Depending on which payment processor you’re using, we offer native integrations for the following:
Alternatively, you can also send sale events manually using our SDKs or the POST /track/sale API endpoint.
