What is this?

A Dockerized CLI application which allows you to automatically sync different resources between two commercetools projects. As of now, these are the supported resources:

• CartDiscounts
• Categories
• InventoryEntries
• Products
• ProductTypes
• Types
• States
• TaxCategories
• CustomObjects
• Customers
• ShoppingLists

Prerequisites

• Make sure you have installed docker to run the docker image.

• The following fields are required to be set on the following resources (and sub-resources), if they will be synced:

  Resource/ Sub-resource	Required Fields
  Product	key
  Product Variant	key, sku
  Product Variant Asset (if exists)	key
  ProductType	key
  Type	key
  Category	key
  Category Asset (if exists)	key
  CartDiscount	key
  InventoryEntry	sku
  State	key
  TaxCategory	key
  CustomObject	container AND key
  Customer	key
  Customer Address	key
  ShoppingList	key
  ShoppingList LineItem - Product Variant	sku
  ShoppingList TextLineItem	name

• Set the following environment variables before running the application

  export SOURCE_PROJECT_KEY = "source-project-key"
  export SOURCE_CLIENT_ID = "sourceClientId"
  export SOURCE_CLIENT_SECRET = "sourceClientSecret"
  export SOURCE_AUTH_URL = "https://auth.eu-central-1.aws.commercetools.com/oauth/token" #optional parameter
  export SOURCE_API_URL = "https://api.eu-central-1.aws.commercetools.com" #optional parameter
  export SOURCE_SCOPES = "manage_project" #optional parameter
  
  export TARGET_PROJECT_KEY = "target-project-key"
  export TARGET_CLIENT_ID = "targetClientId"
  export TARGET_CLIENT_SECRET = "targetClientSecret"
  export TARGET_AUTH_URL = "https://auth.eu-central-1.aws.commercetools.com/oauth/token" #optional parameter
  export TARGET_API_URL = "https://api.eu-central-1.aws.commercetools.com" #optional parameter
  export TARGET_SCOPES = "manage_project" #optional parameter

  Note: For *_AUTH_URL and *_API_URL parameter values, you can use different authentication endpoints and API endpoints.

  Note 2: Project-sync uses manage_project scope by default. if you want to use different scope you might set SOURCE_SCOPES and TARGET_SCOPES environment variables, for instance: export SOURCE_SCOPES="manage_products" or export TARGET_SCOPES="manage_products, manage_customers"(separate multiple scope elements with a comma).

  Note 3: be careful there is no trailing slash in the URLs. Please make sure the URLs do not include / as this would result in a wrong URLs like so and fail the process: https://auth.eu-central-1.gcp.commercetools.com//oauth/token

Usage

usage: commercetools-project-sync
 -f,--full                           By default, a delta sync runs using
                                     last-sync-timestamp logic. Use this
                                     flag to run a full sync. i.e. sync
                                     the entire data set. This option must
                                     be added after `-s` option.
 -h,--help                           Print help information.
 -r,--runnerName <arg>               Choose a name for the running sync
                                     instance. Please make sure the name
                                     is unique, otherwise running more
                                     than 1 sync instance with the same
                                     name would lead to an unexpected
                                     behaviour. This option must
                                     be added after `-s` option. (optional parameter)
                                     default: 'runnerName'.
 -s,--sync <args>                    Choose one or more of the following modules
                                     to run: "types", "productTypes",
                                     "cartDiscounts", "customObjects",
                                     "categories", "products",
                                     "inventoryEntries", "states",
                                     "taxCategories", "customers",
                                     "shoppingLists" or "all".
    --syncProjectSyncCustomObjects   Sync custom objects that were created
                                     with project sync (this application). This option must
                                     be added after `-s` option.
    --productQueryParameters         Pass your customized product fetch limit
                                     and a product projection predicate to filter  
                                     product resources to sync in the JSON format. 
                                     Example: "{\"limit\": 100, \"where\": \"
                                     published=true\"}" could be used to fetch 
                                     only published products to sync and limit 
                                     max 100 elements in one page. This option must
                                     be added after `-s` option.                
 -v,--version                        Print the version of the application.

Delta Sync

By default, running the sync without using -f or --full option would run a delta sync; which means that only resources which have been modified since the last time the sync has run would be synced. The application achieves that by persisting the last sync timestamp on commercetools using CustomObjects on every sync run.

The last sync timestamp customObject for a runner name testRun running a Type Sync from a source commercetools project with the key java-sync-source-dev1 looks as follows:

{
  "id": "0ee39da2-21fd-46b4-9f99-44eae7f249a1",
  "version": 2,
  "container": "commercetools-project-sync.testRun.typeSync",
  "key": "java-sync-source-dev1",
  "value": {
    "lastSyncDurationInMillis": 972,
    "applicationVersion": "3.1.0",
    "lastSyncTimestamp": "2019-05-24T11:17:00.602Z",
    "lastSyncStatistics": {
      "processed": 0,
      "failed": 0,
      "created": 0,
      "updated": 0,
      "reportMessage": "Summary: 0 types were processed in total (0 created, 0 updated and 0 failed to sync)."
    }
  },
  "createdAt": "2019-05-24T11:18:12.831Z",
  "lastModifiedAt": "2019-05-24T11:19:01.822Z",
  "lastModifiedBy": {
    "clientId": "8bV3XSW-taCph843-GQTa8lf",
    "isPlatformClient": false
  },
  "createdBy": {
    "clientId": "8bV3XSW-taCph843-GQTa8lf",
    "isPlatformClient": false
  }
}

• The container has the convention: commercetools-project-sync.{runnerName}.{syncModuleName}.
• The key contains the source project key.
• The value contains the information lastSyncDurationInMillis, applicationVersion, lastSyncTimestamp and lastSyncStatistics.
• These custom objects will not be synced with the custom object syncer unless the option --syncProjectSyncCustomObjects is added.

Note: Another customObject with the container convention commercetools-project-sync.{runnerName}.{syncModuleName}.timestampGenerator is also created on the target project for capturing a unified timestamp from commercetools.

Running a Full sync using -f or --full option will not create any customObjects.

Running Multiple Syncers

The application can sync multiple resources. For example, to run type and productType sync together, the -s option with types productTypes as below:

-s types productTypes

Running ProductSync with custom product query parameters

You might pass your customized product fetch limit, and a product projection predicate to filter product resources to sync in the JSON format.

For instance:

-s products -productQueryParameters "{\"limit\": 100, \"where\": \"published=true AND masterVariant(attributes(name=\\\"attribute-name\\\" and value=\\\"attribute-value\\\"))\"}"

Predicates provide a way for complex filter expressions when querying resources. Refer commercetools docs for more details.

Note: The value of the productQueryParameters argument should be in JSON format and as shown in the above example, please use escape character \ for the nested double quote values. Example:

-s products -productQueryParameters "{\"limit\": 100, \"where\": \"published=true AND masterVariant(key= \\\"variantKey\\\")\"}"

Scopes

If you want to narrow down the credential scopes instead of using manage_project scope, make sure you grant the correct scopes for every resource you intend to sync.

Required scope for all resources

For project-sync to run successfully, it is required to grant access to custom objects for the target project. Therefore, one of the below scope must always be granted for any resources: manage_products OR manage_orders OR manage_customers OR manage_key_value_documents

Required scope per resource

In addition to the above-mentioned scope, the table below shows the minimal scope for every resource

Resource	Scope
Cart discounts	manage_cart_discounts
Categories	manage_categories
Inventory entries	manage_products
Products	manage_products
Product types	manage_products
Types	manage_types
States	manage_states
Tax categories	manage_tax_categories
Custom objects	manage_products OR manage_orders OR manage_customers OR manage_key_value_documents
Customers	manage_customers
Shopping lists	manage_shopping_lists
