Title: 400 invalid_request – Required parameter(s) missing or wrong. Last modified: April 3, 2020 --- # 400 invalid_request – Required parameter(s) missing or wrong. * Resolved [pilinski](https://wordpress.org/support/users/pilinski/) * (@pilinski) * [6 years, 2 months ago](https://wordpress.org/support/topic/400-invalid_request-required-parameters-missing-or-wrong/) * Hallo, * there was a similar case on this forum already: [https://wordpress.org/support/topic/error-somethings-not-working/](https://wordpress.org/support/topic/error-somethings-not-working/) * However, the solution does not work in my case… 🙁 1. I installed the plugin 2. I created the app at the [https://goto-developer.logmeininc.com/](https://goto-developer.logmeininc.com/) 3. I entered the Consumer Key and Secret 4. Save all settings 5. “CLICK HERE TO CONNECT WITH MY GOTOWEBINAR APPLICATION” 6. I’ve got a pupup window with the question i I would allow the access 7. my Answer was “Yes” 8. I was back at the“/ wp-admin/options-general.php?page=wp-gotowebinar” page * [gotowebinar] shorcode presents the following message: * ``` Something's not working. It looks like the API call to GoToWebinar isn't succeeding. This may be because you are on a trial account. Unfortunately API calls can't be made to GoToWebinar accounts on a trial. If you do have a full GoToWebinar licence please try re-authenticating the plugin again by pressing the 'Click here to get Auth and Key' button in the plugin settings. You should also clear the cache or turn the cache off in the plugin settings and this should resolve the issue. ``` * I tried both methods: your app and my own app. Same result. * I tried to clear the webinar cache, but I get message “The cache was not cleared because it has previously been cleared in the last 24 hours. Please wait until this time before trying to clear the cache again.”. Always… 🙁 * I cannot find the ‘Click here to get Auth and Key’ button in the plugin settings. * Last bt not least in the support –> Connection Log I can find multiple entries like: * ``` 400 invalid_request - Required parameter(s) missing or wrong. ``` * Any one could give a helipin hand? * Kind regards, Maciej Viewing 8 replies - 1 through 8 (of 8 total) * Plugin Author [Northern Beaches Websites](https://wordpress.org/support/users/northernbeacheswebsites/) * (@northernbeacheswebsites) * [6 years, 2 months ago](https://wordpress.org/support/topic/400-invalid_request-required-parameters-missing-or-wrong/#post-12632041) * Hi [@pilinski](https://wordpress.org/support/users/pilinski/), * Do you have a paid GoToWebinar account? * Thanks, * Thread Starter [pilinski](https://wordpress.org/support/users/pilinski/) * (@pilinski) * [6 years, 2 months ago](https://wordpress.org/support/topic/400-invalid_request-required-parameters-missing-or-wrong/#post-12637269) * Hello [@northernbeacheswebsites](https://wordpress.org/support/users/northernbeacheswebsites/), * yes, we have the GoToWebinar Pro licence valid till end of April 2020. * When I try to test the API accoring to the [https://goto-developer.logmeininc.com/how-get-access-token-and-organizer-key](https://goto-developer.logmeininc.com/how-get-access-token-and-organizer-key) instruction, I get a redirect to the following address: * ``` https://www.forum-fronius.pl/wp-admin/options-general.php?page=wp-gotowebinar&code={very-long-code-is-here} ``` * and the message in the browser window: * ```
