emarsys-rb

Simple Ruby wrapper for the Emarsys API.

Note

This fork was created because the original author doesn't seem to be merging PRs anymore. If that gets rectified, I'll close this repo. In the meantime I'll start release from the original version + 1.0.0 (e.g. 0.4.0 -> 1.4.0).

Installation

gem install emarsys

Emarsys API Hint

This wrapper tries to implement all available methods of the Emarsys API in a Ruby-like fashion. However, the Emarsys API lacks a decent amount of methods that you expect an API to provide. Thus, if methods are missing or a certain implementation style was chosen it is most likely due to the inconsistency of the API itself. Feel free to get in touch or submit a pull request if you encounter any problems.

Must-known facts about the Emarsys API:

• Emarsys uses internal IDs as field identifiers. E.g. 'email' is mapped to the value 3. This gem tries to work around this by letting you specify a field mapping constant.
• certain methods require the specification of a key-field, e.g. the email (internally referred to as '3' again).
• Return values differ from method to method due to the way the Emarsys API is implemented. Thus, a Hash as a return value or an Array of Hashes was chosen as the global return object. Basically it is a parsed JSON response.
• Please refer to the Emarsys API documentation for detailed information on parameters, return values or error codes.
• The list of available countries is defined by Emarsys, and uses internal Emarsys-specific IDs. A utility class is provided to map ISO 3166-1 alpha-2 data (aka 2-letter country codes) to internal Emarsys country IDs.

Configuration and Setup

Authentication

Authenticate with the api credentials provided by your Emarsys account manager.

Emarsys.configure do |c|
  c.api_username = 'my_username'
  c.api_password = 'my_password'
  # OPTIONAL, defaults to https://api.emarsys.net/api/v2
  c.api_endpoint = 'https://suite5.emarsys.net/api/v2'
end

It is also possible to configure multiple Emarsys accounts like this:

Emarsys.configure(account: :foo) do |c|
  c.api_username = 'foo_username'
  c.api_password = 'foo_password'
end

Emarsys.configure(account: :bar) do |c|
  c.api_username = 'bar_username'
  c.api_password = 'bar_password'
end

When your application uses only one Emarsys account you will need to add:

Emarsys.allow_default_configuration = true

to your configuration.

Field Mapping

As said before, Emarsys loves IDs. For using an API, they are evil. This gem provides an easy way to adjust the individual field settings. Internally a Ruby Mapping Constant is used, which that can be overwritten. It will be picked up automatically. E.g.:

# Complete overwrite
Emarsys::FieldMapping.set_attributes([
  {:id => 0, :identifier => 'interests', :name => 'Interests'},
  {:id => 1, :identifier => 'firstname', :name => 'First Name'},
  {:id => 2, :identifier => 'lastname',  :name => 'Last Name'},
])

# Add to the Mapping-Constant
Emarsys::FieldMapping.add_attributes({:id => 100, :identifier => 'user_id', :name => "User-ID"})

All Emarsys predefined system fields are prefixed with an underscore, e.g. '_firstname' or '_revenue' in order to not clash with individual mappings.

Mapping Country IDs from ISO country codes

A utility method is provided to map to Emarsys internal country IDs from ISO 3166-1 alpha-2 two-letter country codes. You can pass a symbol or a string, and case is ignored.

>> Emarsys::Country.from_iso('GB')
=> {:id=>184, :name=>"United Kingdom"}

>> Emarsys::Country.from_iso(:af)
=> {:id=>1, :name=>"Afghanistan"}

>> Emarsys::Country.from_iso('us')
=> {:id=>185, :name=>"United States of America"}

Rate Limiting

The Emarsys API documentation states you can make "at least 200 requests per minute", which is reasonably slow - in practice, the Emarsys API seems to handle rates of up to about 60-70 req/sec before complaining.

If you exceed the limit, the Emarsys API returns an HTTP 429 'Too Many Requests' response. The client library will raise an error in this case.

Interacting with the API

Responses

Each API request returns a response object, which exposes the following methods:

• code: HTTP status code
• text: 'replyText' from parsed JSON
• data: 'data' from parsed JSON
• code: 'replyCode' from parsed JSON

If the replyCode is not 0, an exception will be raised.

Multiple accounts

If you configured multiple Emarsys accounts, you will need to pass the keyword argument account to every API call, e.g. Emarsys::Condition.collection(account: :foo).

Endpoints

Emarsys::Contact.create(key_id: 4980, key_value: 10, params: {1 => "Jane", 2 => "Doe", 3 => "jane.doe@example.com"})

# Update a contact with key_field (one example with mapped identifier, one without)
Emarsys::Contact.update(key_id: 'email', key_value: "jane.doe@example.com", params: {firstname: "John", lastname: "Doe"})
Emarsys::Contact.update(key_id: 3, key_value: "jane.doe@example.com", params: {1 => "John", 2 => "Doe"})
