1. Contact
Monitored on working days.
Support is available in Croatian and in English. Write in whichever you prefer.
2. What to include
Most requests are answered on the first reply when they say what was expected and what happened instead. It helps to include:
- the email address of the account you were signed in as;
- your company name, so we can find the right workspace;
- what you were doing — the page you were on, or the question you asked;
- what you expected, and what happened instead;
- roughly when it happened, including the time zone, which lets us find the matching server-side record;
- a screenshot, where the problem is visible on screen.
Please do not send passwords, access tokens, or API keys. We never ask for them, and we do not need them to investigate.
3. Connecting an AI assistant
For questions about TOP Connect — connecting the platform to Claude or ChatGPT — start with the TOP Connect documentation, which covers the prerequisites, the exact server address, the two consent scopes, and how to disconnect.
If the assistant connects but every request is refused, the account almost certainly lacks a plan that includes TOP Connect, or the MCP access permission. An administrator of your company can check both in TOP under Settings.
When reporting a connector problem, please also say which assistant you were using, what you asked, and what came back.
4. Security reports
Suspected vulnerabilities and other security concerns go to
support@tender-op.com
with SECURITY in the subject line. We respond to
security reports promptly and will keep you informed while we
investigate.
Please do not disclose a suspected vulnerability publicly before we have had a chance to address it.
5. Accounts, billing, and data requests
Questions about subscriptions, seats, invoices, or plan changes can go to the same address. Include the company name the subscription is under.
