This call to Prestashop Web Services failed and returned an HTTP status of 401. That means: Unauthorized

Overview 


You encountered a problem when using the wizard to integrate your prestashop and you get the answer shown in the screenshot below. This article explains what the problem is and how to fix it because it is possible that the issue comes from different reasons.




Option 1 : Prestashop services aren't enabled

Sometimes those settings aren't set to properly so prestashop won't authorize a 3rd party to connect to their servers.
Go to your prestashop into "advanced settings" -> "webservice" and make sure both options are set on "Yes".
The CGI option isn't mandatory if your server isn't compatible.



Option 2 : API key's permissions aren't set

After creating a new API key in prestashop, you need to make sure it has all the permissions so that BoostMyShop can access everything.
In order to do that, go to "advanced settings" -> "webservice" and select the API key you used in BoostMyShop. Then tick all the boxes in the permissions and press save.




Option 3 : HTaccess authorization


This configuration rewrites all requests to your front controller and adds the HTTP_AUTHORIZATION header.

There are multiple ways to get Apache to pass this header:

1/ If you have SetEnv module enabled you can use this one
# Requires Module
# SetEnvIf Authorization "(.*)" HTTP_AUTHORIZATION=$1

2/ Or you can configure via RewriteRules in the Directory or VirtualHost.

# RewriteCond %{HTTP:Authorization} ^(.*)
# RewriteRule .* - [E=HTTP_AUTHORIZATION:%1]

3/ If you have another Front controller, you can configure rewrite like this
RewriteRule .* /index.php [L,QSA]
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:AUTHORIZATION}]
