Custom content lets you build tailored dashboards and views inside entity pages — charts, summaries, operational displays. These are developed with Seal’s support team and deployed as part of your configuration. If you need a custom view for your workflows, contact us and we’ll scope it with you.

E-signature

Custom content iframes can request an e-signature from the user via the hosted helper script: 
<script src="/api/esign.js"></script>
This exposes a single method: 
const success = await Seal.requestESignature();
requestESignature() opens the Seal e-signature modal in the parent application. It returns a promise that:
  • Resolves to true when the user successfully signs
  • Rejects with an Error if the user cancels or the signature fails
The script must be loaded inside a custom content iframe served by Seal — it communicates with the parent application via postMessage and will reject if called outside an iframe.
