The consent endpoint records cookie banner interactions to a compliance audit log. It is designed to be called from client-side consent banners — no authentication is required, and errors are swallowed so a network failure never blocks the user experience.

This endpoint is public — no API key or session cookie is required.

Record consent

POST /api/consent
Content-Type: application/json

Request body

Field	Type	Required	Description
`action`	`accept_all` \| `decline_all` \| `save_preferences`	Yes	The user's consent action
`analytics`	boolean	No	Whether the user accepted analytics cookies
`marketing`	boolean	No	Whether the user accepted marketing cookies

Response

{ "ok": true }

The response is always { "ok": true } — errors are swallowed server-side to ensure the consent banner never blocks the user. If the audit log write fails, the event is silently dropped.

What gets recorded

Each call to this endpoint creates a row in the compliance_audit_log table with the following fields:

Field	Value
`event_type`	`consent_granted` if any category is enabled; `consent_revoked` if `decline_all` or all categories are `false`
`event_method`	`banner` for `accept_all` / `decline_all`; `preference-center` for `save_preferences`
`ip_address`	Anonymised (hashed + truncated) for GDPR compliance
`user_agent`	Stored for audit context
`metadata`	`{ analytics, marketing, action }`

IP addresses are hashed before storage — MisarMail never stores raw IPs in the audit log, satisfying GDPR Article 25 (data minimisation) while still maintaining Article 7 audit trail requirements.

GDPR audit trail

Under GDPR Article 7(1), controllers must be able to demonstrate that consent was given. The compliance_audit_log table provides an immutable record of every consent interaction, including:

When consent was given or withdrawn
Which categories were accepted
The mechanism used (banner vs preference center)
Anonymised IP + user agent for context

This log is accessible via the Audit Log settings endpoint.

Banner integration example

Call this endpoint when your consent banner resolves. You do not need to wait for the response.

# Accept all cookies
curl -X POST https://api.misar.io/mail/api/consent \
  -H "Content-Type: application/json" \
  -d '{ "action": "accept_all", "analytics": true, "marketing": true }'

# Decline all
curl -X POST https://api.misar.io/mail/api/consent \
  -H "Content-Type: application/json" \
  -d '{ "action": "decline_all", "analytics": false, "marketing": false }'

// Fire-and-forget — never await to avoid blocking the UI
function recordConsent(
  action: 'accept_all' | 'decline_all' | 'save_preferences',
  categories: { analytics?: boolean; marketing?: boolean }
) {
  fetch('/api/consent', {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify({ action, ...categories }),
  }).catch(() => {
    // Silently ignore — consent recording must never fail visibly
  });
}

// Usage
recordConsent('accept_all', { analytics: true, marketing: true });
recordConsent('save_preferences', { analytics: true, marketing: false });

Notes

MisarMail's own marketing website uses this endpoint internally for its cookie banner
If you embed MisarMail tracking pixels or analytics on your own site, call this endpoint when your users interact with your consent banner so MisarMail's tracking respects their choice
Consent records are retained for 3 years in compliance with typical GDPR audit retention requirements
