Hi! @elisa.zoom After ‘Invalid redirect url’ Error occurred, the following details were corrected. **Redirect URL for OAuth** `https://pljec.cloud/pljec_zoom/ -> https://pljec.cloud/pljec_zoom` (Modified) **Add Allow lists** `https://pljec.cloud/pljec_zoom/` (new addition) I thought the ‘/’ after the URL could be the problem, so I fixed it. ---

Oh I am sorry, I misunderstood @Sapiens ! I was able to look into your published app and it looks like your redirect URL (dev) is: [https://dev.pljec.cloud/pljec\_zoom](https://dev.pljec.cloud/pljec_zoom) And in your allow list you have an extra “/” Could you please remove it and re submit your app for update so the changes will apply to the published app. Thanks, Elisa ---

Hi! @elisa.zoom The [https://dev.pljec.cloud/pljec\_zoom](https://dev.pljec.cloud/pljec_zoom) URL is for development. working. The [https://pljec.cloud/pljec\_zoom](https://pljec.cloud/pljec_zoom) URL is for product services. This is what doesn’t work. The set screen is attached again. ![zoom_pljec](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/3X/7/5/75fbb2ee1cf89f059b754cdb95079f59dce74ace.jpeg) ---

Hi @Sapiens Thanks for sharing more details with me. I was able to look on our end and it looks like the redirect urls that are in your published app are different from the ones that you are sharing with me. Did you recently add those?? if so, please resubmit for update so this changes will update on our end. If you have any other questions please send me DM and I can send you a link to my Calendar so we can hope into a Zoom call. Cheers, Elisa ---

Hi! @elisa.zoom Changed after redirect url 4,700 error occurred. I think that the modification of the app information is not the root cause of the error. Resubmitted the app. ---
