**Your software**  
My Mautic version is: 4.4.9  
My PHP version is: 8.0.29  
My Database type and version is: 10.6.12-MariaDB-0ubuntu0.22.04.1  
I am doing some integration using Mautic api to 3rd party crm and For this I need to use the Mautic Rest api and I have successfully authenticated the api But I am unable to get or post contacts using api. I always keep getting 500 internal server error in api response while trying to execute api request in postman. Could anyone please help us regarding this?

Hi @joeyk  
I am simply trying to retrieve the contacts from Mautic using the GET Api request. But it doesn’t seems to work.

Hi,  
What is your call exactly?  
Also: when you make your call, do you have @ or : in your password?  
Are you using Basic Auth?

The @ in your password is messing up things. Try to change the password without spec chars for testing.  
And don’t encode.
