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 great thing about SecuMailer is that it’s so easy and user-friendly.”

  • Key Benefit: Encrypted file sharing, user-friendly interface

Nancy Hennekens explains why the company chose to use SecuMailer to share large files securely.

We have many audit clients. This requires us to check their entire administration, which means that huge Excel files are regularly sent back and forth.

Until now, employees often had to compress the documents and send them as ZIP files. To make it easier for them, we looked for another solution and came across SecuMailer.

It would be great if our clients could use the upload function to send their large files to us securely. Together with SecuMailer, we are investigating how this can be implemented.

The biggest advantage of securely sharing large files via SecuMailer is that it is so easy and user-friendly.

Excellent! If you have a question or problem, you will always receive a friendly response quickly.

Absolutely. The great thing about SecuMailer is that all the technology runs in the background. As a user, you don't really notice anything.
