German Invoicing API
This is a set of APIs meant for managing electronic invoicing in Germany.
A-Cube API DE helps you to handle E-Invoicing through simple REST APIs.
When you get onboard the A-CUBE API Platform, you will receive:
- username and password for the authentication
You will also need to register a Legal Entity in A-Cube API DE.
This is the process to create and send an invoice explained in a few steps:
- Login into the platform to get a JWT token
- Create a Legal Entity that you wanna use as an invoice sender
- Create an invoice payload in JSON or XML format and send it to
POST /invoices - The invoice payload gets validated, translated into XML format and sent to the recipient
- Every notification will be dispatched in real time to the configured destinations.
Environments
- Sandbox is the environment where you can test the entire platform for free; the communication with the Tax Authority is simulated. The base URL is https://de-sandbox.api.acubeapi.com
- Production is the environment where the communication is real; you can't send an invoice to sandbox. The base URL is https://de.api.acubeapi.com
We support the following TLS protocols: TLSv1_2016 TLSv1.1_2016 TLSv1.2_2018
Authentication
You can find all the information about the authentication here.
Invoice UUID
Every invoice in the platform is identified by a UUID. This key is received for both created and received invoices.
Webhooks
All the messages sent to your endpoint are sent with a POST request.
We manage to send the messages to your endpoints with a queue:
if your endpoint fails (we don't get a 200 family response),
then the webhook system will retry 15 times every 300 seconds with a back-off rate of 1.25 for a total of about 10 hours.
