I am having issues signing in to my Quickbooks account over Zapier. I get this warning: "This site can’t be reachedCheck if there is a typo in api.tradegecko.com."

As I know TradeGecko no longer exists after Intuit acquired it. You should have another inventory management app to integrate with QBO.

Thank you for bringing this to our attention, Erdem.

Integrating applications seamlessly is essential for your workflow, and I want to ensure you receive the appropriate support for your API concerns.

For further assistance, I recommend contacting our dedicated Intuit Development Support team for help given the presence of "api" in the URL you provided for TradeGecko.
