ExpressConsent developer docs

Add a script tag, call captureCDR() on form submit, store the returned cdrId. That’s the entire integration.

1. Add the SDK

Place this in your <head>. Replace YOUR_CID with the CID from your organization settings page in the dashboard.

html

<script
  src="https://sdk.expressconsent.com/sdk/v1/sdk.js"
  data-ec-cid="YOUR_CID"
></script>

2. Capture on submit

javascript

document.getElementById("myForm")?.addEventListener("submit", async (e) => {
  e.preventDefault();
  const result = await window.ExpressConsent.captureCDR();
  if (result) console.log("Evidence saved:", result.cdrId);
  e.currentTarget.submit();
});

3. Store the CDR ID

Save cdrId with your lead/user record. That ID is your evidence reference — use it to find the Certified Digital Receipt (CDR) in the dashboard or via the API.
