Hello My issue is that with the same API key, when I request /collections endpoint with **X-Api-Key** in the request header, it works like fine. but when I do with **apiKey** parameter GET [https://api.getpostman.com/collections/?apiKey=myAPIKey](https://api.getpostman.com/collections/?apiKey=myAPIKey) It responds with a 401 โ€œmessageโ€: โ€œInvalid API Key. Every request requires a valid API Key to be sent.โ€. I made my api key in collection variables to ensure it is the same. can anyone point me to the issue here please ? ![sPv7jRucjC](https://us1.discourse-cdn.com/getpostman/original/2X/b/bd680cdf5c9e17a25d0a4d09a04efb38748ad424.gif) Many thanks ! ---

Hey @UAlee Welcome to the community! ๐Ÿ‘‹ Have you tried the same request, with the Auth token in the URL but removing the trailing forward slash before the `?` Or going to the request settings and disabling the Cookie Jar? Just trying the think or some different things to try ๐Ÿ˜ ---

Hi @danny-dainton Thank you ! I tried that with [https://api.getpostman.com/collections?apiKey={{apiKey}](https://api.getpostman.com/collections?apiKey=%7B%7BapiKey%7D)} And disabled then enabled the cookie jar but in vain I donโ€™t think it is related to Postman client. I tried the request in browser and with vs rest client, always in vain ๐Ÿ˜ฅ could you try to reproduce it please ? btw, all of that to make your newman slack bot work with the Postman API ๐Ÿ˜ƒ ---
