What is an Action Link?
An action link is a URL that, when clicked by a person, triggers a specific "action" — e.g., "clicked," "donated," "signed," etc. The link can include multiple parameters for context, such as:
action: the event that occurred (e.g., "clicked")
Target URL: the destination URL
context (optional): the context in which the action happened
source (optional): the source of the action (e.g., email, SMS)
vendor (optional): the platform that delivered the link
Why Use Action Links?
Action links help you understand how your users interact with your content and allow you to automate follow-ups and personalize the journey. Common use cases include:
Tracking link clicks in emails
Measuring reactions to external campaign links
Triggering automation steps in a user journey
How Does an Action Link Work?
An action link follows this structure:
https://<your-cambuildr-url>/api/v1/t?goto=<target-url>&person={{var:identifier}}&action=<your-action>Additional optional parameters like context, source, and vendor can be added.
Example:
https://join.cambuildr.com/api/v1/t?goto=https%3A%2F%2Fjoin.cambuildr.com%2Fdanke&person={{var:identifier}}&action=clicked&context=overlooked_email&source=email_not_opted_in&vendor=cambuildrImportant: The person={{var:identifier}} parameter is required. It’s the only way to associate the action with a specific person in CamBuildr.
Using Action Links Outside of CamBuildr Emails
If you’re using action links outside of CamBuildr (e.g., in third-party email tools or on external websites), you must ensure that {{var:identifier}} is replaced with the actual identifier of the user.
This means you need to:
Replace
{{var:identifier}}at send time (e.g., using a merge tag or personalization token), orGenerate the final URL dynamically with the identifier already embedded
Otherwise, the action cannot be attributed to a specific person in CamBuildr.
Use the Action Link Generator
CamBuildr offers a visual Action Link Generator to help you create links easily. You’ll find it here.
Just enter the base URL, target URL, and action and optionally, other parameters. The generator builds a ready-to-copy tracking link for you.
