This key lets OneTicket send invoicing requests to your Számlázz.hu account.
Log in to the invoicing account you want to use to issue receipts for your OneTicket orders.
Click the invoice icon in the top-left corner to open the Dashboard.
Near the bottom of the Dashboard, below the users section, you'll find the Számla Agent key management.
Click to create a new key. Name it something you'll clearly recognize later, for example: "OneTicket".
Copy the newly created Számla Agent key to your clipboard. Treat it as confidential, and never send it over a public or insecure channel.
OneTicket uses this key to connect to the correct Számlázz.hu account.
On OneTicket's partner/admin interface, go to invoicing integrations and select Számlázz.hu.
Paste the copied value into the "Számlázz.hu Agent key" field, then save the setting.
Make sure there's no leading or trailing space in the key, and that it comes from the correct business's Számlázz.hu account.
Számla Agent is a separately charged service, regardless of which Számlázz.hu plan you use.
Usage-based fee
Számla Agent can be used even with a free plan, but Agent traffic is billed separately under a tiered fee structure.
A live key means real access
Providing a live key allows the external system to create receipts within your business account.
Test only in a test account
Do development or trial invoicing in a test-status account, since receipts created in a live account may incur fees.
Revoking a key
If you no longer use an integration, delete its Agent key on the Dashboard.
The Számla Agent key grants an external system access to your invoicing account. Only enter it into a trusted system, and if you suspect unauthorized access, delete it immediately and create a new one.
