Payload tracking tells you which channel a guest used to register. You append a value to the registration link, for example... google_ads or newsletter_oct. ONevents saves this value in a separate field for each guest during registration. This allows you to compare campaigns, partners, or QR codes directly in the guest list.
Here's how it works #
You append the parameter to the registration address of your event. ?payload= to:
https://dein-event.onevents.at/register?payload=google_ads

If a guest registers via this link, the following will be displayed google_ads then in the selected extra field of his profile.
Step 1: Define the target field #
1. Go to the event Settings → Login & Registration.
2. Choose from Store payload in this field a free extra field, for example Extra 10.

3. Click on Save settings.
Use a field you don't normally use and give it a value under Settings → User data a descriptive name such as "source" or "campaign".
Step 2: Create links for your channels #
Create a separate link for each channel:
| channel | link |
|---|---|
| Google Ads | …/register?payload=google_ads |
| October Newsletter | …/register?payload=newsletter_oct |
| Partner 123 | …/register?payload=partner_123 |
| QR code at the exhibition stand | …/register?payload=qr_fairstand |
Use short, unambiguous values without spaces or special characters. You can also generate QR codes for posters or flyers from these links.
Important: Append the parameter /register to the address /extra/register, which under Login & Registration displayed, redirects to /register continues and loses the parameter in the process.
Step 3: Check #
1. Open one of your links in a private browser window where you are not logged in, and register with a test address.
2. Open in the event under user the new guest.
3. The value from the link is displayed in the selected extra field.

Evaluate #
- User export: Export the guest list and filter or count by the extra field.
- Admin dashboard: Count the registrations per channel.
%DASHBOARD_SUM("extra_10", "google_ads")%. The counter takes all users of the space into account. More information can be found at [link to relevant page]. Create an admin dashboard.
Frequently Asked Questions #
The value is not being saved. What's the reason for this?
- Under Store payload in this field No field has been selected.
- The link does not lead to
/registeror the parameter is misspelled. - You were already logged in during the test. ONevents will then redirect you directly without requiring registration.
Can I pass multiple values?
A single, continuous text will be saved. If you need multiple pieces of information, use a fixed format, for example: ?payload=src-google_cmp-autumn.
