Hi everyone! I received an Access and Refresh token using the code. When I try to refresh my tokens, I’ve got an error: {“reason”:“Invalid request : Invalid refresh Token{refresh\_token}”,“error”:“invalid\_request”} (Invalid refresh Token{refresh\_token} without spaces) What is the problem? ---

Hi Max, Can you share the curl command that you used when trying to get the refresh token? ---

Hi Ojus, Thanks for your help, but I’ve found a “bug” on your instruction page ![image](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/1X/8a870ffa98585bab17a1157118dac0a87969f8b3.png) what is this? ---

@ojus.zoom I’ve been getting this issue periodically as well. Our users are having to reauthorize too frequently due to this error response happening inconsistently. I know it’s not the code because 99% of the time it works fine. Is there a reason that tokens have to expire after 60 minutes? I work with API’s that handle financial information that last 24 hours, but to deal with a webinar or meeting it’s every hour? What is the rationale for such short time periods? ---
