Signed URLs

One URL. One render. No surprises.

Generate tamper-proof, time-limited URLs for any Orshot template. Share them in emails, embed them in pages, or bake them into Slack — nobody can re-use them without your signature.

Unlimited signed URLs on every paid plan

Tamper-proof

Modifications are signed — nobody can tweak the URL and render something else.

Time-limited

Expire links after minutes, hours or days — your call.

Render from the URL

No API call needed — drop the URL in a browser, inbox or iframe and it renders.

Keep your API key private

Sign once on your backend, share the URL on the front end — key never leaves.

Generate

Sign once on your server, render anywhere.

Call the signed-URL endpoint with your modifications and an expiry. Get back a URL your frontend, email or Slack can hit directly — zero API key exposure.

  • Server-side signing — key stays on your backend
  • Per-link expiry and render quota
  • Modifications baked into the signature — tamper-proof
  • Works with every Orshot template
