Quickstart

This quickstart uses the TEST environment and the SDK-generated TEST certificate. Use a real XAdES certificate or KSeF token for DEMO and PRODUCTION.

1. Check the CLI

uv run ksef2 --help
bash

2. Create a TEST profile

Profiles keep repeated non-secret options in one local config file. The TEST certificate auth method is useful for local development:

uv run ksef2 profile create test-company \
  --env test \
  --nip 5261040828 \
  --test-cert
bash

Authenticate with that profile and print the SDK auth token payload:

uv run ksef2 --profile test-company --json auth login
bash

Global options such as --profile, --env, --nip, --test-cert, and --json must appear before the command group.

3. Query invoice metadata

uv run ksef2 --profile test-company --json \
  invoices metadata \
  --role seller \
  --date-from 2026-01-01T00:00:00Z \
  --all
bash

For token authentication in CI, skip the profile and pass direct root options:

uv run ksef2 --nip "$KSEF2_NIP" --token "$KSEF2_TOKEN" --json \
  invoices metadata \
  --role seller \
  --date-from 2026-01-01T00:00:00Z \
  --all
bash

4. Send one invoice and get a UPO

uv run ksef2 --profile test-company \
  invoices send invoice.xml \
  --wait \
  --upo-dir upos \
  --receipt invoice-receipt.json
bash

By default, invoices send uses online mode. The receipt file lets you check status or download the UPO later without managing the underlying session:

uv run ksef2 --profile test-company \
  invoices status --receipt invoice-receipt.json --wait

uv run ksef2 --profile test-company \
  invoices upo --receipt invoice-receipt.json --out invoice-upo.xml
bash

5. Send a directory or batch

uv run ksef2 --profile test-company \
  invoices send invoices/ --receipt-dir receipts
bash

Directory input includes direct child *.xml files. Add --recursive for nested directories. Use --mode batch when the files should be submitted as one batch:

uv run ksef2 --profile test-company \
  invoices send invoices/ --mode batch --wait --upo-dir upos
bash
