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.

What is Data Haven?

SecuMailer is built with security by default in mind. This means we only store data when it is absolutely necessary. In most cases, an email can be delivered directly to the recipient. In these cases, the data is kept on our platform for only a very short time, usually less than one second, during the sending process.

When two-factor authentication (2FA) is required, the recipient must authenticate before the email can be delivered. In this situation, the data must be stored securely until the authentication is completed.

With Data Haven, your organization controls where this temporary data is stored. All data is kept within your own infrastructure, in a secure Kubernetes environment that you manage. Instead of being stored on SecuMailer’s platform, everything stays inside your organization’s environment Once delivery is possible, the message is transferred through a secure connection and deleted from your Kubernetes environment.

Why is Data Haven important?

Data Haven is especially relevant for organizations that must meet strict requirements for data handling. It supports:

Internal data sovereignty policies
Confidentiality and regulatory obligations
Protection against risks linked to non-European cloud providers
Data Haven gives you full control over temporary email storage, keeping sensitive data secure within your own infrastructure.
