Hey @jaycooperbell, Make sure you are making a POST request. If you are making a GET request, a Zoom HTML error page will be returned. Thanks, Tommy ---

Hi Tommy, I was definitely making a post request, I tried both in my Node.js code as well as directly in postman. See screenshot ![image](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/2X/d/d2bf58fc701cb800b83e000b72863777bf5cd4ad.png) ---

Hey @jaycooperbell, Thanks for clarifying. Can you share a screenshot of the Zoom HTML page that is being returned in your response in postman? Thanks, Tommy ---

Trying to paste the html in but it seems to not let me so here is the preview from postman ![image](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/2X/c/c9ee92d5b537c9bc41f8992e79b0fad70249fa81.png) ---

Hey @jaycooperbell, It seems something might be wrong with your authorization header. Can you double check you are [base64 encoding your key and secret](https://marketplace.zoom.us/docs/guides/auth/oauth#step-2-request-access-token) with a `:` in between correctly? Thanks, Tommy ---

Hey Tommy, I’ll double check but I’m nearly positive I am. Either way shouldn’t it return an error JSON response instead of an HTML page? ---

Oh god I just looked and when i refactored my code i forgot the `toString('base64')` when creating the buffer… massive facepalm moment. Still wondering why it wouldn’t return a json error response though? ---

Hey @jaycooperbell, Haha, did you get it working after finding the base64 issue? 🙂 We will work on improving this error message. Thanks, Tommy ---

I did! As soon as I actually base 64’d it worked. I should have realized the token I removed from my original comment wasn’t base64… I was just super confused how the endpoint was returning html instead of json. Thought there must have been something else amiss! Thanks Tommy ---
