commercetools

Configuration

From a MACH composer configuration file, you can configure the following items in commercetools:

• currencies
• languages
• countries
• shipping zones
• channels
• taxes
• stores

For more information about these configuration options, see the syntax.

More fine-grained control

MACH composer provides a couple of basic configuration options which in most cases are sufficient and is set up very quickly.
If you need more control over the configuration in your project, you can load custom configuration through a new component which would include the necessary Terraform configuration for that.
For example a commercetools-setup-component.

API client management

MACH composer is provided by admin credentials which allows MACH composer to fully manage your commercetools project.

Each component that implements functionality that needs to communicate with commercetools needs their own set of credentials. The component is responsible for creating the necessary API client credentials for that specific component, with only the most necessary scopes set.

One way a component could facilitate in this would be to define the following in your Terraform config:

locals {
  ct_scopes = formatlist("%s:%s", [
    "manage_orders",
  ], var.ct_project_key)
}

resource "commercetools_api_client" "client" {
  name  = "api-extension"
  scope = local.ct_scopes
}

Stores

MACH provides built-in commercetools Stores support.

It's possible to

• Configure your stores within a MACH composer configuration (see example below)
• Define store-specific variables and secrets per component

For example, when two stores are defined uk-store and nl-store, these can be used to configure your component:

component:
  - my-component:
    variables:
      FROM_EMAIL: mach@example.com
    store_variables:
      uk-store:
        FROM_EMAIL: mach@example.co.uk
      nl-store:
        FROM_EMAIL: mach@example.nl
    store_secrets:
      uk-store:
        MAIL_API_KEY: 5kg6Z4HxgLMfBjYj5BOg
      nl-store:
        MAIL_API_KEY: i1hajIJ92LPNYGB2p3W1

The component can use the correct variables based on the context that is decided based on incoming requests or other information available.

Using store-aware context in components

Although MACH composer provides a data structure for managing your configuration in different contexts, it is the responsibility of the component itself to parse this data structure correctly, and apply the right configuration in the right context.

Read the parse store variables and secrets how-to for more information.

Outside MACH composer configuration

If you don't want to manage the stores from the MACH composer configuration itself, you still have the possibility to define them in the configuration so that components can use store variables and receive a full list of the stores available.

This is done by setting a store to managed: false:

commercetools:
  stores:
    - key: uk-store
      managed: false
    - key: nl-store
      managed: false

  languages:
      - en-GB

  currencies:
      - GBP
      - EUR
  countries:
      - GB
      - IE
      - NL
  channels:

        distribution_channels:
          - DIST-EUR
        inventory_channels:
          - INV
      - key: nl-store
        name:
          en: NL store
        languages:
          - nl-NL
        distribution_channels:
          - DIST-EUR
        inventory_channels:
          - INV

Integrate with components

When commercetools is set as a component integration, the component should have the following Terraform variables defined:

• ct_project_key
• ct_api_url
• ct_auth_url
• ct_stores
