REST API

Developer portal ›

SecuMailer has a REST API for sending secure emails. Both the GDPR and the NTA 7516 functionality are fully accessible via this API.

The API is documented with OpenAPI specification 3.0.1.

The REST API has webhook functionality, which means that the SecuMailer platform can communicate email events with an HTTPS endpoint of the sender.

SMTP API

The SMTP API is usually the simplest integration option for many backend applications because backend applications often have a provision for an SMTP client on board.

We have successfully integrated for customers with Salesforce, SAP and Centric. We have also successfully integrated with patient file systems such as Medisoft Dossier Manager.

GraphQL API

The SecuMailer platform offers insight into email events. This can be done on the basis of a (push) webhook call (see REST API above) and on the basis of a (pull) GraphQL endpoint.

The Challenge

  • Referrals, discharge letters, lab results and invoices must reach the right person fast.

  • Portals create friction and lower completion rates.

  • Regulations (GDPR/AVG, NEN 7510, NTA 7516) demand strong controls.

  • Need both: security and simplicity.

The SecuMailer Approach

  • ✅ Runs behind Outlook/Microsoft 365 and Google Workspace.

  • ✅ Compose and send as usual.

  • ✅ Encryption, policy, 2FA applied automatically.

  • ✅ Messages arrive in inbox; delivery and access logged for audit/legal proof.

  • ✅ After delivery, content removed for data minimisation.
