Developer API enhancements for attachments and email delivery tracking

Update June 19, 2026

We’ve added two useful enhancements to the Elorus Developer API, making it easier to automate expense management and monitor client communications.

Upload primary attachments

You can now upload the primary attachment of an expense or purchase invoice directly via the API. This is the file that represents the actual document you received, such as the supplier invoice or receipt.

Track email delivery status

We’ve also introduced a new endpoint, /sent-email-messages, that allows you to track the delivery status of emails sent through Elorus.

When sending invoices, estimates, receipts, client statements, or other documents by email, your integration can now retrieve information about the related email message and monitor its delivery status more easily.

You’ll find the new functionality in our Developer API documentation.
