This symfony bundle implements service to use the API.


Make sure Composer is installed globally, as explained in the installation chapter of the Composer documentation.

Applications that use Symfony Flex

Open a command console, go to your symfony project directory and execute:

$ composer require alexandret/evc-bundle

Open env (or env.dist) file and search the new created lines to configure variable

###> alexandret/evc-bundle ###
EVC_API = ''
###< alexandret/evc-bundle ###

Look at the configuration section for more explanation.

Applications that don't use Symfony Flex

Step 1: Download the Bundle

Open a command console, enter your project directory and execute the following command to download the latest stable version of this bundle:

$ composer require alexandret/evc-bundle

Step 2: Enable the Bundle

Then, enable the bundle by adding it to the list of registered bundles in the config/bundles.php file of your project:

// config/bundles.php

return [
    // ...
    Alexandre\EvcBundle\AlexandreEvcBundle::class => ['all' => true],

Open your env file and add the value of necessary configuration variables

Step 3: Create a alexandre_evc.yaml file

Create a alexandre_evc.yaml file under the config/packages subdirectory. Then copy and paste these lines:

  api_id: '%env(EVC_API)%'
  username: '%env(EVC_USERNAME)%'
  password: '%env(EVC_PASSWORD)%'

Do NOT replace env by your password. You have to configure your .env file as described in the below paragraph.


EvcBundle needs data information. You shall complete them in your env file.

  • EVC_API: The api key provided by evc support
  • EVC_USERNAME: Your account number
  • EVC_PASSWORD: Your API password. This is NOT your account password. It's a separate password that you get from the EVC office.

Here is a sample:

###> alexandret/evc-bundle ###
EVC_API = sample_key
EVC_USERNAME = my_name
EVC_PASSWORD = my_password
###< alexandret/evc-bundle ###

How to mock your requests to the API?

You want to test your application with mocked customer and avoid to send data to the real API? By default, our bundle is created to use a requester service that embed Unirest/Request. In your config/package/dev repository, add new lines at the end of the service.yaml file. (Do not hesitate to create a new service.yaml file if there is no file yet. If you use flex to install this bundle, this is already done! :)

# config/packages/dev/service.yaml
# config/packages/test/service.yaml
        class: Alexandre\EvcBundle\Service\EmulationService
            $api: '%env(EVC_API)%'
            $username: '%env(EVC_USERNAME)%'
            $password: '%env(EVC_PASSWORD)%'

Instead of calling the RequesterService, dev environment will use an EmulationService.

There is four declared customer.

  • 11111 is the identifier of a customer that does not exists. Use it when you want to test your application with a non-existent customer
  • 22222 customer exists, but he is not a personal user of your reseller. Use it when you want to test your application with a non-personal customer
  • 33333 customer exists and he is a personal user with 42 credits.
  • 44444 is a personal customer too. He has 42 credits too.
  • 55555 Each time you call the 55555 customer, Emulation service will throw a NetworkExceptionto test your application as if evc API wasn't reachable.
  • 66666 Each time you call the 66666 customer, Emulation service will throw a CredentialException to test your application when your configuration is wrong.
  • 77777 Each time you call the 77777 customer, Emulation service will throw a LogicException. We do not think it is useful, but if you want to test. A logic exception could be throw if API changes or if the answer is truncated.


  • NetworkException: Network exceptions are thrown if is not reachable.
  • CredentialException: Credential exceptions are thrown when you do a misconfiguration on your credentials.
  • LogicException: Logical exceptions are thrown when is returning a not expected response. It could happen if there is a bug on this bundle, or if the api changes.
  • EvcException: The three previous exceptions inherits the EvcException.
