Google Calendar integration - API token will not authorize

I have installed SuiteCRM to a local server (running at localhost) and all is working fine. I have been able to integrate email and other features, however I am struggling to get Google Calender integration to work.
I have followed the installation guide without error, generating the API Key, JSON script etc. However, after I step through the token validation process I still get the message: Current API Token is: UNCONFIGURED

I have searched this forum and tried various “tricks” that others have suggested. I have even gone through the process of setting up my local server with an SSL - but I still can’t get the API Token to CONFIGURE.

Any help greatly appreciated.

In ‘Authorized redirect URIs’, add a full URI to the ‘saveGoogleApiKey’ Entry Point.


  1. Click on the “Refresh” Button to Create oAuth Client Id.

Download JSON Credentials file.

I have followed this tutorial, many times, no errors are thrown but I still can’t get to “Current API Token is configured” is still shows as “UNCONFIGURED”

Please help - I have tried everything.

Some additional detail. I am running off a local server using WAMP. My redirect is to http://localhost/suiteCRM/etc

After I step through the configuration is redirects to a blank page.

I do all the steps, generate an authentication, upload the JSON file etc - no problems. I go to the user profile and step through all the details to link the accounts, but on completion it ends at a blanks screen (i.e. the final redirect page is not working) and the token authentication icon still shows as not authenticated.

It is the page that starts with this URL: http://localhost/suitecrm/index.php?entryPoint=saveGoogleApiKey&code= etc etc

It is pointing to the correct location for the file but the page is not responding. I have error reporting turned on with my web server and no error is being thrown to the browser.

Looking at the suitecrm.log file I note the following errors:

Exception handling in … \SuiteCRM\include\MVC\Controller\SugarController.php:400

Exception in Controller: cURL error 60: SSL certificate problem: unable to get local issuer certificate (see

I updated my php_curl.dll file and have progressed to the stage where I get a Google email indicating SuiteCRM is linked to my Calander - but SuiteCRM is still displaying API Token as UNCONFIGURED and no synching is occuring

I had a similar issue with the white page and ended up going back in to the Google API developer console and the URI had been changed to some default address. I added the correct URI with the entryPoint address and was able to authenticate with my gmail address. Now my new problem is no sync after all this. I see in the logs a message about the Calendar bean is missing. I will document it and open a new thread.

What issue are you facing
please share a screenshot
if you still facing same issue

Hi @cherub-chum
Thanks for appreciating my work and approve to update as a Docs

I am also struggling to get the Google Calender integration to work. I follow the instructions to create a JSON Credentials file on the Google Developer Console.

Then I go to the Admin Google Calendar Settings to upload the credentials JSON file, but everything with a .json extension is greyed out and inaccessible. The files with a .txt extension are accessible in the same folder.

What is going on?

Here is explained step wise step creation and installation of JSON keys.

i also tried to follow the official documentation

Someone knows how to solve this?
