Custom Branding

Custom branding lets you replace ZipZign's default branding with your own on the signing/payment pages and outgoing emails.

What you can customize

Setting	Description
Brand name	Replaces "ZipZign" in emails and page headers
Brand color	Primary color used in buttons and accents (hex)
Logo URL	Your logo shown in emails and on hosted pages
Reply-to email	The reply-to address on all outgoing emails

Configuring branding via API

curl -X POST https://zipzign.com/api/user/branding \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "brandName": "Acme Contracts",
    "brandColor": "#2563EB",
    "logoUrl": "https://acmecorp.com/logo.png",
    "replyTo": "contracts@acmecorp.com"
  }'

Configuring branding via dashboard

Go to Dashboard → Settings → Branding
Fill in your brand name, color, and logo URL
Click Save

Branding changes apply to all new documents immediately. Existing documents retain the branding active at the time they were created.

Logo requirements

URL must be publicly accessible (HTTPS)
Recommended size: 200×60 px or similar horizontal logo
Formats: PNG or SVG preferred

Per-document branding

You can override branding on a per-document basis:

{
  "type": "signable",
  "branding": {
    "brandName": "Acme Legal",
    "brandColor": "#DC2626",
    "logoUrl": "https://acmecorp.com/legal-logo.png"
  },
  "content": "...",
  "signers": []
}

What signers and payers see

Email subject: "[Your Brand Name] — Please sign your document"
Email sender: noreply@zipzign.com (reply-to your configured address)
Signing page header: Your logo + brand color
Payment page: Your logo + brand color on the Stripe checkout
