DATEV API Connection Check

This guide explains how to verify whether the DATEV Connect interface is reachable and functioning correctly.

1. Introduction

By default, the local URL of the DATEV Connect interface is: 

http://localhost:58454

 

In practice, this address may vary, for example: 

https://firm:58452
http://servername:58454

 

Important: Replace localhost with the actual reachable address of your server.

2. Key Endpoints to Test

The following endpoints can be accessed via a browser or tools like Postman:

  • Check User Identity

GET http://<address>:58454/datev/api/iam/v1/Users/me

 

Returns information about the currently connected user (IAM interface).

  • Retrieve Order Overview 

GET http://<address>:58454/datev/api/order-management/v1/orders?top=10&skip=0&filter=completion_status+eq+'created/planned'&expand=suborders

 

Shows open/planned orders available for import.

 

  • Test Access with Service User

 
GET http://<address>:58454/datev/api/master-data/v1/employees?top=1&skip=0

 

Verifies if the service user has access to employee data (required for time entries).

 

3. Notes About the Address

  • Always replace localhost with the actual server name or IP address.

  • If using HTTPS, make sure to use port 58452.

Examples: 
http://localhost:58454
http://someserver:58454
https://firm:58452
https://memt1234:58452

 

4. Note on HTTPS

If accessing the interface via HTTPS, a valid SSL certificate must be installed and port 58452 must be open.
