**Description** This is my first integration zoom api test, for this test I try to list my meetings. But I have code error 124 with message: Invalid access token. The list meetings have two parameters. The first is the userid, in this param I set the Client Id generated in my App Credentials. The second is the oauth\_access\_token, in this param I set the token generated with the Installation URL ![error](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/2X/9/938f5aefe063a1e876b06cf677a9f71283b2f527.png) ---

Hey @monge.armando, For the oauth access token, you need to use the token generated in the URL to first get an access\_token, then you can use it in that field. Here are the step by step instructions: [https://marketplace.zoom.us/docs/guides/auth/oauth](https://marketplace.zoom.us/docs/guides/auth/oauth) Thanks, Tommy ---

Hi Tommy, I followed all steps of the instructions from the begin. First, registered my app credentials step by step to finish in “Install” button. ![installbutton](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/2X/c/cc5484b0535c80bd319c94828850dfd3625e754b.png) Second, I obteined the code in a URL registered. ![code](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/2X/0/03f3ff0dc16042cd362b1cacb8e7b4e24adecad1.png) Finally, I used this token in the list meetings test unsatisfactorily. ---

Hey @monge.armando, You can’t use that token in URL to call API. You have to **use that token in the URL to request an access\_token first.** Please see step 2: [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 ---

Thanks, I didn’t see the step 2 in the creation of token access. ---
