subscriber.subscribe_ip The IP the subscriber subscribed from. This can be null if it is unknown. String
subscriber.custom_fields An array of entries matching the definition found below (1). Hash
subscriber.skip_autoresponders Do not run autoresponders for this new subscriber (see 2.1 below). false Boolean
subscriber.autoresponder_filter Only run the autoresponders that match this case-insensitive string glob (see 2.4 below). Subscription Autoresponder Sequence* String
subscriber.autoresponder_exclude_reacted Do not run autoresponders if this subscriber has a reaction in the queue (see 2.5 below). true Boolean

(1) Each entry in the specified custom_fields hash must have the following keys. The keys for the hash is the name of the custom field.

Key Meaning Example Type Present for Custom Field Types
name The name of the custom field which this entry represents. First Name String All
value The string value of the custom field. James McGuy String text, text_multiline, select_single_dropdown, select_single_radio
value The integer value of the custom field. 9182 Integer number
value The boolean value of the custom field. true or false Boolean boolean
value The date value of the custom field. 2000-02-17 String date
value The list of values selected for the custom field. Array of strings select_multiple_checkboxes

(2) In order for an autoresponder to be triggered for later sending, the following must be true.

  1. The skip_autoresponders field must not be enabled.
  2. The autoresponder must trigger on Subscription.
  3. The autoresponder trigger must be configured with the Run From API? option enabled.
  4. If specified, the autoresponder_filter field will reduce the list of autoresponders that are run to those whose name matches the glob, where * is a wildcard character.
  5. If specified, the autoresponder_exclude_reacted field will cause all autoresponders to be skipped if any autoresponder remaining at this point contains a reaction in the queue for this subscriber. This only evaluates autoresponders that: (a) are configured with Run from API? as true (step 3), (b) match the pattern provided in autoresponder_filter if present (step 4), and (c) are paused or un-paused.


A successful response will return the subscriber record using the format described in the “Get subscriber details” section of the API.

A failure will return a standard error response with an explanation of what went wrong.
