Parameter tokens are placeholders that let you capture specific information about your survey participants. They help identify participants in your study results and can be used in redirect URLs when you're working with a recruitment panel.

Why use parameter tokens?

  • Track participants: Know who completed the survey without asking them to enter their details again.

  • Integrate with recruitment panels: Automatically track participants from recruitment sources.

  • Chain studies: Carry a participant identifier through multiple studies without asking them to enter their details multiple times.

What parameter tokens are available with Optimal Workshop?

  1. token

    The token parameter is used to identify a participant uniquely. It must be referred to as token in all instances.

    Example:

    https://yourstudy.com/?token=abc123

    Note: This parameter ensures that every participant has a unique identifier. You cannot replace token with any other name.

  2. tag

    The tag parameter can be replaced with a custom name or chain of characters to track additional data. You can rename tag to suit your needs, such as source, group, or campaign.

    Example:

    https://yourstudy.com/?source=Facebook

  3. i

    The i parameter is used to pull a participant's identifier from one study into another. This is useful for chaining studies, to ensure that participants are identified correctly through all studies without requiring you to ask for information multiple times.

    Key Reminders:

    • Always use token exactly as is.

    • You can replace tag with custom names to suit your tracking needs.

    • Use i when linking participants from one study to another.
