Redirects

Redirect users after form submission

Default Behavior

By default, after a successful submission, users see a simple “Thank you” page from Spike.

Custom Redirect

In Form Settings

Set a default redirect URL in your form settings. All submissions will redirect there.

Using _next Field

Override the default with a hidden field:

<form action="https://api.spike.ac/f/YOUR_FORM_SLUG" method="POST">
  <input type="hidden" name="_next" value="https://yoursite.com/thanks">
  
  <input type="email" name="email" required>
  <button type="submit">Subscribe</button>
</form>

Dynamic Redirects

Use different redirects based on form context:

<!-- Contact page -->
<input type="hidden" name="_next" value="https://yoursite.com/contact/thanks">

<!-- Careers page -->
<input type="hidden" name="_next" value="https://yoursite.com/careers/thanks">

Conditional Redirects

Use Form Rules to redirect based on submission data:

1. Go to form settings → Rules
2. Create a new rule
3. Set conditions (e.g., “department equals sales”)
4. Add action: “Redirect to URL”
5. Enter the redirect URL

Example rules:

Condition	Redirect
department = sales	/thanks/sales
department = support	/thanks/support
Default	/thanks

AJAX Submissions

For AJAX submissions, handle the redirect in JavaScript:

const response = await fetch('https://api.spike.ac/f/YOUR_FORM_SLUG', {
  method: 'POST',
  body: formData,
  headers: { 'Accept': 'application/json' }
});

if (response.ok) {
  window.location.href = '/thanks';
}

Pass Submission Data

Include submission data in the redirect URL:

<input type="hidden" name="_next" value="https://yoursite.com/thanks?email={{ email }}">

Be careful not to expose sensitive data in URLs. Use this only for non-sensitive fields.

Same-Origin Redirects

For security, redirects must be to:

• The same domain as the form’s allowed domains
• Or any HTTPS URL if no domain restrictions are set

Troubleshooting

Redirect not working?

1. Check the URL is valid and accessible
2. Ensure it’s HTTPS (HTTP redirects may be blocked)
3. Check domain restrictions in form settings
4. For AJAX, make sure you’re not setting Accept: application/json if you want automatic redirect
