**Description** I’ve seen this posted multiple times but I’ve yet to see an answer. I’m trying to get an access token with a Vue app but I keep getting a 403. **Error** 403 Forbidden. Also getting `CORS header ‘Access-Control-Allow-Origin’ missing` but I’m thinking that’s due to the 403? Not sure. **Which App Type (OAuth / Chatbot / JWT / Webhook)?** OAuth **Which Endpoint/s?** `https://zoom.us/oauth/token` **How To Reproduce (If applicable)** I’ve followed the instructions exactly, including the Authorization Code in base64. **Screenshots (If applicable)** ![Screenshot 2020-12-28 015410](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/3X/c/9/c900b0abd758a1adb852c2f5fea349dbbfecd2a7.jpeg) **Additional context** Add any other context about the problem here. ---

“All Zoom OAuth and API endpoints must be called from the server side of your application. If called from the client side, CORS errors will be thrown.” Reading is fundamental smh. I TOTALLY missed this part. Welp, nevermind then. ---

Hey @lloydinator, You are correct, all APIs must be called from the server side or you will see CORs errors! 🙂 If anything else comes up, feel free to reach out! Thanks, Tommy ---
