Error getting access token: cURL error 60

Question

Error getting access token: cURL error 60

André vieira 5

hi,
my company asked me to developed a php web application that uses the microsoft graph api(for some sort of meeting inviting), but I've been facing a lot of issues, such as confusing documentation. My first question is, how do I generate the token I need to use in the application? I already have the following parameters:

  Display name: Teste
    Application (client) ID: xxxx-xxx-xxxxxxxxxxxxxx
    Object ID: xxxx-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
    Directory (tenant) ID: xxxxx-xxxxxxxxxxxxxxxxxxxxxxxxxx
    Client secret value: xxxx~xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
    Client secret ID: xxxxxx-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

What else do I need besides that?

============================

the second is, I've been following this documentation:
https://learn.microsoft.com/pt-br/graph/tutorials/php-app-only?tabs=aad&tutorial-step=3

but, I got this error after the 2nd step(image attached):
Error getting access token: cURL error 60: SSL certificate problem: unable to get local issuer certificate (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) for https://login.microsoftonline.com/4c7eb97d-7d42-4246-9eae-e9621e9ba93d/oauth2/v2.0/token

Can you please help us?

Hi @André vieira ,

Thanks for reaching out.

This error occurs because the curl verifies and makes a secure connection request using self-signed certificate. When it does not find the valid certificate, it throws an error.

Did you configure this false as mentioned in https://learn.microsoft.com/en-us/graph/tutorials/php?tabs=aad&tutorial-step=3

'http_errors' => false, 'curl' => [ CURLOPT_FAILONERROR => false ] ]);

@André vieira

Did you add user.read mail.read and mail.send delegated permissions to your registered application?

Also are you passing client id directly here or through .env file?

yes yes, I added them, I'm doing the same way as in the tutorial, so through the .env file. but I'll try directly to see if it works
