Branding

Branding sets what signers see: your name, your accent colour and your logo on the signing pages and emails. You can take our name off, and list the sites allowed to embed signing.

Set your branding

Call update_branding with a regular key. Agent keys can't change branding. Every field is optional, and fields you leave out stay as they are.

curl https://docuinked.com/v1/branding \
  -H "Authorization: Bearer $DOCUINKED_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"display_name": "Cedar Row Rentals",
       "accent_color": "#0F766E",
       "logo_png_base64": "iVBORw0KGgo...",
       "hide_docuinked_branding": true,
       "embed_origins": ["https://app.example.com"]}'

The reply is the branding as it now stands, the same as get_branding.

get_branding returns display_name, accent_color, has_logo, logo_url, hide_docuinked_branding and embed_origins.

Branding for each of your customers

On a platform, each sub-account has its own branding. Add the header DocuInked-Account: acct_... to the same call to set it for one customer. See sub-accounts.

What branding changes, and what it doesn't

Signer pages, signing emails and embedded signing use your name, logo and colour. With branding hidden, emails come from your name alone. Without it, they read "your name via docuinked".

Some things stay ours. The sealed PDF is sealed by docuinked, and its certificate page says so, because the seal and the evidence are what we stand behind. Signing links use our domain, and emails come from our address. Custom signing domains and custom email sending domains are coming, but they aren't available yet.

Common questions

Why must embed origins use https?

A signing page holds a person's signature and consent, so it may only sit inside a page that is itself private in transit. Plain http origins, paths and wildcards are refused.

Can I use an SVG or JPEG logo?

Not yet. The logo must be a PNG under 200 KB. A transparent PNG about 300 pixels wide looks best on both the page and the email.

Does removing your branding change the certificate?

No. The certificate page inside the sealed PDF always names docuinked as the service that sealed it, so anyone checking the file knows where to verify it.
