  const response = await fetch(
    `https://api.baanx.com/v2/consent/onboarding/${consentSetId}`,
    {

  if (!response.ok) {
    const error = await response.json();
    throw new Error(`Linking failed: ${error.details.join(', ')}`);
  }

Integration Workflow

​
Best Practices

Store the consentSetId in your session or database until user registration completes:
await sessionStore.set(`consent_${onboardingId}`, consentSetId);

const storedConsentSetId = await sessionStore.get(`consent_${onboardingId}`);
await linkUserToConsent(storedConsentSetId, userId);
Check if linking has already occurred before attempting:
async function linkUserIfNeeded(consentSetId: string, userId: string) {
  try {
    return await linkUserToConsent(consentSetId, userId);
  } catch (error) {
    if (error.status === 409) {
      const consentSet = await getConsentSetById(consentSetId);
      if (consentSet.userId === userId) {
        console.log('Already linked to this user');
        return consentSet;
      }
      throw new Error('Consent set linked to different user');
    }
    throw error;
  }
}
Remove temporary data after successful linking:
const result = await linkUserToConsent(consentSetId, userId);
await sessionStore.delete(`consent_${onboardingId}`);

​
Important Notes

One-Time Operation: Each consent set can only be linked once. The linking action is recorded in the audit trail and cannot be undone.
Audit Trail: The linking action is automatically recorded in the user’s consent audit trail with timestamp and metadata.
