Make a call to this endpoint to opt-in a user to a subscription.

Notes:

• A legal disclosure is required when a user is opted-in programmatically.

  • For marketing messages, required legal language must be included.

  • For transactional messages, you must include a transactional opt-in unit.

• By default, if a subscription already exists, it will try and record the attempt to create the subscription again. For TEXT subscriptions, this will result in a message being sent to the person indicating that they are already subscribed.

• Requests to opt-in subscribers must either contain a) a sign-up source id or b) both a locale and a subscription type.

  • The unique identifier of a sign-up source can be found in the Sign-up Units tab of the Attentive platform in the ID column.
    If this value is provided in the request, then this sign-up unit will be used for opting in the user in the request.

  • Callers of this endpoint have the option to omit signUpSourceId and, instead, provide both a locale and a subscriptionType (see below for field details).
    Given the locale and subscription type, Attentive will resolve any matching API opt-in units. To opt-in a user to a subscription without a signUpSourceId and exclusively based on locale and subscription type,
    there must be exactly one API sign-up unit that matches the provided locale and subscription type. Conversely, requests that contain a locale and a subscription type
    that do not have a corresponding sign-up unit or that have multiple matching sign-up units will receive a 400 response and will not opt a user into a subscription.

• For users in either France or Italy, in accordance with compliance updates documented here, we set an email pixel tracking
  consent attribute as part of opting in an email subscriber. This is set by default when the locale of a subscriber is in France or Italy.
  We expose the capability in this endpoint to set this consent on behalf of the user via the pixelTrackingConsent parameter. This is a boolean parameter which when provided indicates whether or not a subscriber has consented
  to email pixel tracking. When this endpoint is called with pixelTrackingConsent = true and an email on the UserDto, the email subscription will be created with that tracking consent, visible in subscriber attributes. If
  it is not passed in at all the consent defaults to false.
  NOTE: This parameter will only be honored if it is passed in with a signUpSourceId, otherwise we will not save the attribute.

• Phone numbers must be submitted in e164 format.
