This article explains how to connect your SuperFaktúra account to the app. 👉 To connect, follow this step-by-step guide (3 minutes).
🔑 What you need
Four credentials from your SuperFaktúra account. In the app, Where can I find my credentials? shows where they are.
URL: starts with http:// or https://, without a “/” at the end.
API email
API key
Company ID: numbers only.
Open SuperFaktúra | Integration app » Settings menu » Connection section » paste all four » Save
Testing with a sandbox: you can also connect a SuperFaktúra sandbox account. Enter https://sandbox.superfaktura.sk as the URL, and the sandbox account’s API email, API key and Company ID in the other fields.
✅ Success message? You’re good to go!
When you save, the app checks the connection with SuperFaktúra and loads your numbering sequences. Then choose them under Content » Numbering sequences.
The integration needs a SuperFaktúra plan with API access (premium). Without it the app still connects, but documents fail with error 4-402.
❌ Error message? Check these, and click Save again:
Make sure each credential is in the right field (for example, don’t paste the API key into the URL field).
Check for typos or extra spaces.
Enter the URL without a “/” at the end, and the Company ID with numbers only.
If the connection fails, the numbering sequences you chose before are cleared. Choose them again after you connect.
Several stores can use the same SuperFaktúra account. See Can I connect multiple stores to one SuperFaktúra account?.
