Sylius : Fresh install but API does not work

I am a beginner in Sylius and i'm trying to use the API, but it does not work. Each result is "404 Page not found".

Steps :

Creating an apache2 vhost (hostname : myproject.local
Installing Sylius (1.10) with official documentation (Project + Database + Front compilation)
Adding some content with the admin panel
Creating new customer from Front Office

Everything is OK but when i'm trying to create a user with the API, the response is the "Route not found (404 Not Found)" HTML page. (This is the very first API call from the official documentation : Sylius API doc)

That is my OS details :

Distributor ID: Ubuntu
Description:    Ubuntu 21.04
Release:    21.04
Codename:   hirsute

I am using Apache2 and MySQL :

Server version: Apache/2.4.46 (Ubuntu)
Server built:   2021-09-28T10:57:42

mysql  Ver 8.0.27-0ubuntu0.21.04.1 for Linux on x86_64 ((Ubuntu))

When i use the command :

php bin/console debug:router api

I can see 189 results, i tried some, for example :

URL : http://myproject.local/api/v2/docs, but the result is the same

Did i miss something ?

Solution

Well, i forgot to active the API :

As the documentation says, "The new unified Sylius API is still under development" so this feature needs to be enabled.

Edit config/packages/_sylius.yaml to add :

sylius_api:
    enabled: true

Now the API is activated, the routes no longer respond 404.

Last thing, before you can actually use the API you need to generate a JWT key pair otherwise the API calls will return "Unable to create signed JWT from given configuration".

To do that, use the JWT package (Lexik Repository) :

php bin/console lexik:jwt:generate-keypair

Now everything is good you can use the API, enjoy :)
