WAX automatically adds UTM parameters to every link sent in your campaigns and automations. This lets you track the performance of your WhatsApp actions precisely in your analytics tools, with no manual setup on your side.
Good news: you can customize this behavior to fit your CRM needs, directly from the platform settings.
What you need to know
Before you set anything up, keep these 3 rules in mind:
WAX never replaces a parameter already in a link. If a link already contains a UTM (for example because you added it manually), WAX only adds what's missing and never touches what's there.
An empty field = a disabled parameter. If you empty the
utm_mediumfield, for example, this parameter simply won't be added to your links anymore.utm_campaignhas a dynamic default value. By default, this field isn't fixed text: it's a token that automatically inserts the name of your campaign or flow. Handy, so you don't have to rename this parameter for every send.
Where to set your UTMs
📍 Settings → Attribution → UTM tracking
All UTM tracking settings are here .
Step by step
1. Open the settings
Go to Settings → Attribution → UTM tracking
2. Turn automatic UTMs on or off
Use the Automatically add UTM parameters toggle to turn the feature on or off globally.
3. Set your UTM fields
Fill in the values to fit your reporting needs:
Parameter | Default value | What it's for |
utm_source |
| Identifies the traffic source (here, the WAX platform) |
utm_medium |
| Identifies the channel used (WhatsApp) |
utm_campaign | Dynamic token = name of the campaign/flow | Identifies the specific marketing action behind the click |
💡 CRM tip: if you track performance by channel in a tool like GA4, keep a UTM naming scheme consistent with your other channels (email, SMS, etc.) to make cross-channel comparisons easier.

⚠️ Changes apply immediately to all future sends: campaigns and automations. Links sent before the change are not affected.
