​
This guide uses the following endpoints

​
To add an authorized user to an account, you must

  1. Create a person application
  2. Use the additional person application flow
  3. Issue the card

​
1. Create a Person Application

person_application objects represent natural persons who are applying for new bank accounts or to be added to existing bank accounts. Before you can add a person to an account, you must create a person_application to represent them. To create a person_application, make a POST request to the /apply/person_application endpoint. 
curl -u $API_KEY_ID:$API_KEY_VALUE https://api.treasuryprime.com/apply/person_application \
    -H 'Content-Type: application/json' \
    -d '{
          "bankdata": {
            "ip_address": "127.0.0.40"
          },
          "citizenship": "US",
          "date_of_birth": "1732-02-22",
          "email_address": "[email protected]",
          "first_name": "George",
          "last_name": "Washington",
          "phone_number": "2025551111",
          "physical_address": {
            "street_line_1": "1600 Pennsylvania Ave",
            "city": "Washington",
            "state": "DC",
            "postal_code": "20500"
          },
          "tin": "111222444"
        }'
This will return the person_application object with a unique id: 
{
  "bankdata": {
    "ip_address": "127.0.0.40"
  },
  "citizenship": "US",
  "created_at": "2019-03-02T11:55:14Z",
  "date_of_birth": "1732-02-22",
  "email_address": "[email protected]",
  "first_name": "George",
  "id": "apsn_01d5w7mvmwvy",
  "last_name": "Washington",
  "middle_name": null,
  "occupation": null,
  "phone_number": "2025551111",
  "physical_address": {
    "street_line_1": "1600 Pennsylvania Ave",
    "street_line_2": null,
    "city": "Washington",
    "state": "DC",
    "country": "US",
    "postal_code": "20500"
  },
  "updated_at": "2019-03-02T11:55:14Z",
  "userdata": null
}
The id for person application is prefixed with apsn_, which aids in distinguishing them from the person objects created at the end of the application process.

​
2. Create an Additional Person Application

Once the person_application representing the authorized user you wish to add to an account has been created, you can add them to the account by making a request to the additional_person_application endpoint: 
curl -u $API_KEY_ID:$API_KEY_VALUE https://api.treasuryprime.com/apply/additional_person_application \
    -H 'Content-Type: application/json' \
    -d '{
          "bankdata": {
            "ip_address": "127.0.0.40"
          },
          "account_id": "acct_1029384756",
          "person_application_id: "apsn_01d5w7mvmwvy",
          "role": "authorized_user"
        }'
This will start an additional_person_application to add the supplied person_application to the specified account, with the given role. The response will look like this: 
{
  "account_id": "acct_1029384756",
  "bankdata": {
    "ip_address": "127.0.0.40"
  },
  "created_at": "2019-03-02T11:55:14Z",
  "id": "aapa_01d5w7mvmwvy",
  "person_application_id": "apsn_01d5w7mvmwvy",
  "role": "authorized_user",
  "status": "pending",
  "updated_at": "2019-03-02T11:55:14Z",
  "userdata": null
}
The status of the application will begin in pending and end in approved; once the application is approved, you can issue a card to the new user.

​
3. Issue the Card

Once the additional_person_application has been approved, you can fetch the person_application attached to it and look up the person created and linked to the account: 
curl -u $API_KEY_ID:$API_KEY_VALUE https://api.treasuryprime.com/apply/person_application/apsn_01d5w7mvmwvy

{
  "first_name": "George",
  "secondary_email_address": null,
  "bankdata": {
    "ip_address": "127.0.0.40"
  },
  "phone_number": "+1 202-555-1111",
  "mailing_address": null,
  "occupation": null,
  "physical_address": {
    "street_line_1": "1600 Pennsylvania Ave",
    "street_line_2": null,
    "city": "Washington",
    "state": "DC",
    "postal_code": "20500",
    "country": "US"
  },
  "person_id": "psn_11gqnx6f69zv0g",
  "middle_name": null,
  "updated_at": "2021-10-28T19:06:55Z",
  "gov_id": null,
  "document_ids": [],
  "id": "apsn_11gqkcek69rv55",
  "citizenship": "US",
  "date_of_birth": "1991-02-22",
  "last_name": "Washington",
  "user_id": null,
  "email_address": "[email protected]",
  "created_at": "2021-10-27T20:08:51Z",
  "userdata": null
}
The person_id attribute of the person_application object is what is required to create a card; it is prefixed with psn. Once you have the id of the person you wish to issue a card to, you can make a call to issue them a card in the normal way: 
  curl -u $API_KEY_ID:$API_KEY_VALUE https://api.treasuryprime.com/card \
    -H 'Content-Type: application/json' \
    -d '{
          "account_id": "acct_1029384756",
          "person_id": "psn_11gqnx6f69zv0g5",
          "card_product_id": "cdpt_w10r2sebv0nl"
        }'
This will return a card object: 
{
  "account_id": "acct_1029384756",
  "card_controls": null,
  "card_product_id": "cdpt_w10r2sebv0nl",
  "cvv": null,
  "created_at": "2021-02-19T20:42:40Z",
  "expiration": "0225",
  "fulfillment": {
    "status": "issued"
  },
  "id": "card_zuhqnmz7e085",
  "last4": "3385",
  "pan": null,
  "person_id": "psn_11gqnx6f69zv0g5",
  "pin_is_set": false,
  "status": "unactivated",
  "updated_at": "2021-02-19T20:42:41Z",
  "userdata": null
}
