d_autowinner_enabled
boolean

The default setting for automatic winner selection on new campaigns

d_autowinner_percentage
string

The default percentage that will be sent for the split-test portion of the campaign (Note: This value is returned as a string to prevent floating-point conversion errors)

d_autowinner_delay_amount
integer

The default number of units of time that the campaign will wait before finishing after a split-test.

d_autowinner_delay_unit
string

The default unit used in calculating the delay duration.

d_autowinner_metric
string

The metric used to decide the winner. See Automatic Winner Selection Metrics for more information.

has_format
boolean

true if this mailing list uses the email_format field.

has_confirmed
boolean

true if this mailing list uses the confirmed field.

custom_headers_enabled
boolean

true if this mailing list uses custom headers. If true, custom_headers must be set.

custom_headers
string

The content of the custom headers that will be added to every email sent to this mailing list.

primary_key_custom_field_id
integer

The custom field id of the primary key for the mailing list. If this value is null, then the primary key is the subscriber’s email address.

preview_custom_field_data
hash

The custom field data, see example below.

is_remote_list
boolean

true if this mailing list uses a remote database to retrieve recipient data for campaigns.

database_connection_id
integer

The primary key of the database connection to use on this mailing list.

database_connection_name
integer

The name of the database connection to use on this mailing list.

google_analytics
hash

The Google Analytics configuration.

enabled boolean	Turning this option on enables GreenArrow’s Google Analytics integration.
tracking_id string	Your Google Analytics account’s measurement ID. It should look something like `UA-123456789-11` (for Universal Analytics) or `G-ABCDEFGH` (for Google Analytics 4).
source string	The “Source” field to send to Google Analytics. For example, `newsletter`.
restrict_to_domain_list boolean	Whether to enable this configuration for only links to the domains in `domain_list`.
domain_list array of strings	This key is only present when `restrict_to_domain_list` is `true`. When present, it contains an array of strings, with one string per domain to enable Google Analytics integration on.
open_tracking boolean	Enable Google Analytics open tracking for this mailing list. This is only compatible with Universal Analytics tracking IDs.

Note: This value is returned as a string to prevent floating-point conversion errors. You may send this value as an Integer, Float or String. Posting a value with more than two decimals will cause a validation error. Be careful because IEEE floating point can not exactly represent some decimal values. For example 94.85 is represented as 94.85000000000001 which will cause a validation error if used here. You may want to print to a string using two decimal places of precision.

Preview Custom Field Data

The preview_custom_field_data key is filled with a hash.

{
  "Custom Field Name": {
    "name": "Custom Field Name",
    "type": "text",
    "value": "Bob Example"
  },
  "Next Custom Field": {
    "name": "Next Custom Field",
    "type": "select_multiple_checkboxes",
    "value": [ "Red", "Blue" ]
  }
}

Custom fields which have Preview Custom Field Data values and are not specified in the preview_custom_field_data list, will remain with the same values. In other words: the custom fields provided in preview_custom_field_data are merged in with the existing Preview Custom Field Data custom fields.

Example

Note that the JSON response will not be “pretty formatted” as it is below.

Deleting a mailing list

Deleting a mailing list is a two-step process:

Request a Delete Confirmation Code. This will generate a confirmation code that will be valid for 2 minutes.
Send the confirmation code back to the server.

We do this because deleting a mailing list is what we consider to be a major event. The following happens when a mailing list is deleted:

All subscribers are deleted.
All active/scheduled subscriber imports and exports are cancelled.
All active/scheduled campaigns are cancelled.
The mailing list’s database entry is marked as deleted.

From that point forward, the mailing list will no longer appear in the user interface.

URL

To request the confirmation code:

GET /ga/api/v2/mailing_lists/:mailing_list_id/delete_confirmation_code

To confirm the deletion and start the deletion process:

DELETE /ga/api/v2/mailing_lists/:mailing_list_id/confirmed/:delete_confirmation_code

Response (Request Confirmation Code)

delete_confirmation_code	The token to send back to the server to confirm deletion of the specified mailing list.
delete_confirmation_expires_at	The time at which the included token will no longer be valid.

Example

GET /ga/api/v2/mailing_lists/152/delete_confirmation_code

HTTP/1.1 200 OK

{
  "success": true,
  "data": {
    "delete_confirmation_code": "52e54fcba031fdef04dd3fe75d0ecf3eb0bfaced:1580910582",
    "delete_confirmation_expires_at": "3020-02-05T13:49:42Z"
  },
  "error_code": null,
  "error_message": null
}

Response (Reply with Confirmation Code, Delete Mailing List)

An empty successful response to this request indicates that the mailing list has been marked as deleted and the data cleanup listed above has been done.

Example

DELETE /ga/api/v2/mailing_lists/154/confirmed/52e54fcba031fdef04dd3fe75d0ecf3eb0bfaced:1580910582

HTTP/1.1 200 OK
