You can share data about Legal Entities with banks. Today, Modern Treasury supports creating Legal Entities at Cross River and Column. In the future, additional banking partners will be added.

Get a Connection ID

First, you will need to get the ID of a bank Connection. You can do this by using the List Connections API and filtering for a specific entity.

curl --request GET \
  -u ORG_ID:API_KEY \
  --url 'https://app.moderntreasury.com/api/connections?entity=cross_river' \
  -H 'Content-Type: application/json' \

curl --request GET \
  -u ORG_ID:API_KEY \
  --url 'https://app.moderntreasury.com/api/connections?entity=column' \
  -H 'Content-Type: application/json' \

The response will contain an array, with each item having an ID.

[
  {
    "id": "73140ffe-fbde-4514-b985-f96c0e336192",
    "object": "connection",
    "live_mode": true,
    "vendor_id": "cross_river",
    "vendor_name": "Cross River",
    "vendor_customer_id": null,
    "discarded_at": null,
    "created_at": "2023-08-18T18:49:40Z",
    "updated_at": "2023-11-21T23:20:29Z"
  }
]

[
  {
    "id": "73140ffe-fbde-4514-b985-f96c0e336192",
    "object": "connection",
    "live_mode": true,
    "vendor_id": "column",
    "vendor_name": "Column",
    "vendor_customer_id": null,
    "discarded_at": null,
    "created_at": "2023-08-18T18:49:40Z",
    "updated_at": "2023-11-21T23:20:29Z"
  }
]

Alternatively, an Administrator can find a list of Connections in the web application in the Connections section of Settings.

Create a Connection Legal Entity

Create a Connection Legal Entity with the Connection ID. You also need information about a Legal Entity. You can use the ID of a Legal Entity, which you receive when you create a Legal Entity. Alternatively, you can create a Legal Entity inline.

curl --request POST \
  -u ORG_ID:API_KEY \
  --url https://app.moderntreasury.com/api/connection_legal_entities \
  -H 'content-type: application/json' \

Modern Treasury will synchronously create a Legal Entity at the bank and return a response.

{
  "id": "8425ab9c-725f-4ef1-8102-a582926e753b",
  "object": "connection_legal_entity",
  "live_mode": true,
  "status": "completed",
  "legal_entity_id": "6a33a4df-48ee-4a44-9ebf-66f00c6a2333",
  "connection_id": "8abeaf42-2159-413d-99e9-1e7bf059bc71",
  "discarded_at": null,
  "created_at": "2024-02-05T17:42:33Z",
  "updated_at": "2024-02-05T17:42:33Z"
}

You can monitor the status field to see if the request is processing, completed, denied, or failed. In the future, Modern Treasury will look to support passing back more information from the bank. For example, a bank may put an entity in review and ask for additional documentation, or Modern Treasury can return information about the entity created at the bank.

Today, Modern Treasury currently only supports the creation of a Legal Entity at a bank. In the future, Modern Treasury will support updates. This is important, for example, if an individual entity changes address, or if a business entity has beneficial owner changes.
