How to check the status of an e-invoice?

Tipp

Last updated on 2026-05-15.

When creating an invoice Record (TRANSACTION::INVOICE), a transmission Record (E_INVOICE::TRANSMISSION) is also created alongside to track the delivery of the e-invoice. 

Note: A TRANSACTION::INVOICE in COMPLETED state and FINISHED mode does not necessarily mean the e-invoice was delivered. Diagnostic logs on both Records should be checked to identify any issues.

Step 1: Retrieve the TRANSACTION::INVOICE Record

When creating a TRANSACTION::INVOICE, save the record id from the API response. Then retrieve it using:

GET /records/{{record_id}}

In the response, check the content.logs field:

• If it contains entries with "severity": "ERROR", the invoice failed validation before any transmission was attempted.

• If content.logs is empty, validation passed and the e-invoice was submitted for transmission. Proceed to Step 2.

Step 2: Retrieve the E_INVOICE::TRANSMISSION Record

In the TRANSACTION::INVOICE response from Step 1, locate the content.used_in.id field. This is the ID of the E_INVOICE::TRANSMISSION Record. Retrieve it using:

GET /records/{{content.used_in.id}}

Check the content.logs field:

If it contains ERROR entries, the e-invoice could not be delivered over the e-invoice network. The message field describes what went wrong. To resolve the issue, review the error message, correct the request payload accordingly, and create a new TRANSACTION::INVOICE Record with a new idempotency key.  If the error indicates a network or infrastructure issue, retry after a short delay.  If the issue persists, contact fiskaly support.

 

If content.logs is empty on both Records, the transmission may still be in progress. E-invoice delivery is handled asynchronously and typically completes within seconds to minutes.  If the logs remain empty after several minutes, contact fiskaly support.

Reading a log entry

Each log entry contains the following fields:

Field	Description
severity	ERROR (a failure that prevented delivery) or WARNING (a non-fatal issue, the operation still proceeded).
message	A human-readable description of the issue.
code	A machine-readable code to categorize the log.
date	The timestamp when the log was created.

Example

[
  {
    "$": "Log@v1",
    "date": "2026-05-13T08:32:18.214995449Z",
    "message": "invalid Belgian VAT ID length '12'",
    "severity": "ERROR"
  },
  {
    "$": "Log@v1",
    "date": "2026-05-13T08:32:18.30059009Z",
    "message": "e_invoicing failed: code: invalid format.",
    "severity": "ERROR"
  }
]

Note: WARNING logs are informational and do not affect the transmission of the e-invoice.
