PATCH /subscribers/xxx

{
  "new_address": "[email protected]"
}

It will respond with the details of the subscriber including the new email address.

  • DELETE /subscribers/xxx - unsubscribes a provided subscriber and returns 204 No Content.

{
  "address": "[email protected]",
  "subscriber_list_id": "The id of a subscriber list",
  "frequency": "weekly"

}

It will create a new subscription between the email address and the subscriber list. If a subscription already exists but the frequency is different, the current subscription is ended and a new one with the updated frequency is created. It will respond with the details of the subscription.

A confirmation email will be sent unless the "skip_confirmation_email" flag is set (e.g. if the calling app is going to send it's own confirmation email).

Returns a 201 status code on success; a 403 status code if the subscriber is linked to a GOV.UK Account; or a 404 status code if the subscriber is not known to Email Alert API.

POST /subscribers/govuk-account

{
  "govuk_account_session": "session-token-from-account-header"

{
  "govuk_account_session": "session-token-from-account-header"

  "subscriber": {
    "id": 1,
    "govuk_account_id": "user-id",
    "address": "[email protected]",
