I am trying to test the Create Meeting API using the Test Request at the bottom of the page on [https://marketplace.zoom.us/docs/api-reference/zoom-api/meetings/meetingcreate](https://marketplace.zoom.us/docs/api-reference/zoom-api/meetings/meetingcreate). I click the Get Access Token button to get an access token, I enter the client ID and client secret and leave the other fields as is on the modal that pops up, and then I click the Get Access Token button on the modal. After I do that, I get the following response: ![image](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/2X/4/48b748d56ec5819b1a0ffe4259a6ce1c0ea94c77.png) What am I missing? What am I doing wrong? ---

Hey @eugene, Can you try adding `https://zoom.us` as your redirect url and whitelist url in your OAuth app and try again? Thanks, Tommy ---

@tommy, Thank you for your help, that worked. Now that I have tested generating a create meeting request, how should I set the redirect and whitelist urls in my application, and how will I generate access tokens for my application to generate create meeting requests from my application? ---

Hey @eugene, You will provide the url of where you want your users to land after they install your application. Here is the step by step OAuth guide: [https://marketplace.zoom.us/docs/guides/auth/oauth](https://marketplace.zoom.us/docs/guides/auth/oauth) Thanks, Tommy ---

I tried the steps in the guide and I get “Invalid client\_id: (4,702)” instead of an access token. What could I be missing? ---

Hey @eugene, Are you passing in the authorization basic header? ![Screen Shot 2020-04-23 at 11.44.57 AM](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/2X/2/2f3d9e0e8276a13e90bd8dd86139da2a67408395.png) [https://marketplace.zoom.us/docs/guides/auth/oauth#step-2-request-access-token](https://marketplace.zoom.us/docs/guides/auth/oauth#step-2-request-access-token) Thanks, Tommy ---

From everything I can see I am sending the Authorization header. Is there a specific way I should be sending it? I am encoding the clientID and client secret with a colon in between them and it is Base64 encoded as specified. I have tried both ASCII and UTF-8 encodings. ---

Hey @eugene, Can you private message me your basic header so I can debug? Thanks, Tommy ---

Tommy, I think I figured it out - I wasn’t using the correct HTTP verb/method. I had to specify the method as “POST” (I think it may have been “GET” by default). ---

Happy to hear you figured it out! 🙂 Yes, it is a POST request to get an access token. Thanks, Tommy ---
