I am new user. I have built a construct URL API endpoint to access a third party app we use. The first API I am trying is for getting the access token. However, I cannot get a positive response when calling the API. I am on PRO version. Do you have to have business version for this to work? ---

What error are you seeing on the screen, if any? If you’re on PRO, what exact action are you using to call the API? ---

Error is “Call API : No Response” I am in PRO. I have a Button with a CALL API action. In that action I have the end point as my API URL. Thanks ---

I think the issue here is because you’re using a Business/Enterprise action on a Pro plan. ![image](https://us1.discourse-cdn.com/flex002/uploads/glideapps/original/3X/e/f/ef61181f381aa03ab6c6933ae813311627b2c743.png) How do you have that action in the first place though? Did you have a Business trial? ---

It just shows up as an option. Is there an alternative method? ---

I think you might want to try a JavaScript to column to fetch the URL, but I’m not entirely sure it will work due to CORS.
