I encounter a connectivity issue while connecting my Mautic instance with a Salesforce sandbox. I have successfully created the connected app in Salesforce but I am facing an exception while trying to authorize the application.

**Error:** : **error=invalid\_request&error\_description=missing+required+code+challenge**

Note: I want to mention that I have not created a namespace as I am creating this application within Salesforce.

Can you please post the results from your var/logs folder?

We also need to know the version of Mautic, PHP and MySQL/MariaDB that you’re using.

If this is regarding Mautic 5 then there is already one issue logged about the SF plugin: [Error in configuring salesforce plugin on local instance · Issue #13467 · mautic/mautic · GitHub](https://github.com/mautic/mautic/issues/13467)

@escopecz

Thanks for jumping into this. Also, I have a question as per knowledge articles we need to create the connected app in developer org only with the namespace. Can’t we create connected app in Prod/sandbox without namespace?

A namespace isn’t necessary AFAIK
