Webservice How to Login

[burakpresta3]

Hi ALL, i have fixed lots of different problems by using this forum, thank you for all. Now, i have search whole web, find some topics but no solution. 

My version is Prestashop 1.6.0.11,  PHP version 5.6.36, Enable CGI mode for PHP enabled/disabled doesnt matter

but the files are similar with lastest version.. 

The problem is domain.com/api is not working with just submiting api key. it is just working by using domain/api?ws_key=YOUR_KEY or another version [email protected] ect ect.. 

But i must use a web application which needs domain name and api key, so other solutions are not suitable for me. it is working at localhost by using just api, (same version and database and files) it means it is realted with hosting but i couldnt find any error, made config files error log True, i try to do just view(get) . I asked them, but what is the question ? so no clear answer. 

what can i do ?  any idea ? any way ? 

htaccess is 

RewriteEngine on
RewriteRule . - [E=REWRITEBASE:/]
RewriteRule ^api/?(.*)$ %{ENV:REWRITEBASE}webservice/dispatcher.php?url=$1 [QSA,L]

i read this , same.. https://www.prestashop.com/forums/topic/430312-presta-api-keep-asking-for-username-password-authentication-required/

First idea i have in mind is to debug apache or nginx and see what happens when you try to access /api

Watch out acces and error logs
