[HTMLPub] Using API Keys – Leadpages Knowledge Base

What are API keys?

API keys let you publish, update, and manage pages programmatically — without logging in through a browser. Use them in scripts, CI/CD pipelines, custom integrations, or AI agents.

Pro plan required. API keys are available on the Pro plan. If you're on a Free or Starter plan, upgrade to unlock this feature.

Finding your API keys

Go to Dashboard → Settings → API Keys, or navigate directly to /dashboard/api-keys.

Creating an API key

Enter a descriptive name for the key (up to 64 characters). For example: GitHub Actions, Local Dev, Zapier Bot.
Click Create Key.
Your new key appears in a green confirmation card. Copy it now — it will never be shown again after you dismiss this dialog.
Click Dismiss to close the card.

Limit: Each account can have up to 5 API keys at a time.

Using your API key

Pass the key as a Bearer token in the Authorization header of every request.

Publish or update a page

Use PUT /api/pages/{slug} to create or update a page. This endpoint is idempotent — calling it with the same slug will update an existing page rather than creating a duplicate.

curl -X PUT \
  -H "Authorization: Bearer YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"html":"<h1>Hello World</h1>"}' \
  https://htmlpub.com/api/pages/my-page

List your pages

curl -H "Authorization: Bearer YOUR_KEY" \
  https://htmlpub.com/api/pages

Delete a page

curl -X DELETE \
  -H "Authorization: Bearer YOUR_KEY" \
  https://htmlpub.com/api/pages/my-page

Managing your keys

The keys table shows each key's name, a short prefix (e.g. lp_abc1...), when it was last used, and when it was created.

To revoke a key, click the trash icon next to it. This action is permanent — any integrations using that key will immediately stop working.
