# Redirect Participants to a URL After Their Interview

> Send participants to an external completion page or follow-up experience the moment they finish their Strella interview by configuring a redirect URL.

When participants click **Finish Call**, Strella can immediately send them to any URL you specify — a completion page, a follow-up survey, a thank-you landing page, or any other destination in your research workflow. Setting this up takes less than a minute and keeps your participant experience seamless from start to finish.

## When to Use Post-Interview Redirects

  <Card title="External completion tracking" icon="flag-checkered">
    Route participants to a third-party platform (e.g., a panel provider or survey tool) that needs to register a completion event.
  </Card>

  <Card title="Follow-up experiences" icon="arrow-right">
    Send participants directly into a follow-up survey, diary study, or supplementary task that builds on the interview.
  </Card>

  <Card title="Thank-you pages" icon="heart">
    Land participants on a branded thank-you page that reinforces your company's identity and closes the experience gracefully.

  <Card title="Consistent completion behavior" icon="sliders">
    Ensure every participant in a project arrives at the same post-interview destination, regardless of how they joined the study.

## Set Up Your Redirect URL

<Steps>
  <Step title="Open your project settings">
    Navigate to your project and click **Settings** in the top navigation bar.
  </Step>

  <Step title="Go to Interview Setup">
    Select **Interview Setup** from the settings sidebar.
  </Step>

  <Step title="Enter your redirect URL">
    Find the **Redirect to URL** field and enter the full destination URL, including `https://`.

    ```text theme={null}
    https://customer-redirect-url.com/call-completed
    ```
  </Step>

  <Step title="Save your changes">
    Click **Save**. The redirect takes effect immediately for any participant who completes an interview after this point.
  </Step>
</Steps>

<Warning>
  Always enter a **full absolute URL** that begins with `https://`. A partial URL (e.g., `customer-redirect-url.com/call-completed` without the protocol) will not work and participants will see an error instead of your destination page.
</Warning>

## End-to-End Example

Here's how the full participant journey looks once a redirect is configured:

| Step                                   | What happens                                                             |
| -------------------------------------- | ------------------------------------------------------------------------ |
| **1. Share your study link**           | You send participants: `https://app.strella.io/onboard/abcd1234`         |
| **2. Participant completes interview** | They click **Finish Call** at the end of the session                     |
| **3. Strella redirects**               | Participant lands on: `https://customer-redirect-url.com/call-completed` |

## Common Mistakes to Avoid

<Accordion title="Entering a partial URL without https://">
  The redirect URL field requires a fully qualified URL. If you paste in `customer-redirect-url.com/call-completed` without `https://`, the redirect will fail. Always include the protocol.
</Accordion>

<Accordion title="Saving the setting in the wrong project">
  Redirect URLs are configured per project. If you have multiple active studies, open the correct project before saving. Saving in the wrong project will redirect participants from the wrong study.
</Accordion>

<Accordion title="Forgetting to update the URL when reusing a project">
  If you reuse a project template from a previous study, check that the Redirect to URL field contains the right destination for the new study. Old redirect URLs carry over with the template.
</Accordion>

<Note>
  If you need to pass participant or session metadata to the redirect destination — for example, a participant ID or campaign tag — see [Send Metadata via URL Parameters](/recruiting/send-metadata-via-url-parameters).
