Counterparties

Manage your counterparties, customers, suppliers, vendors, and partners using Numeral

Numeral enables you to manage counterparties and counterparty accounts.

A counterparty is an individual or organization you need to send money to or receive money from. It can be a customer, a supplier, a merchant, a partner, a group company, etc.

A counterparty account is a bank account in the name of the counterparty. A counterparty can have different counterparty accounts, for distinct use cases, in different currencies, or at multiple banks.

1. Create a counterparty

To create a counterparty, simply use the Create a counterparty API endpoint to pass its name and any relevant metadata (such as an internal ID):

curl --request POST \
     --url https://sandbox.numeral.io/v1/counterparties \
     --header 'Accept: application/json' \
     --header 'Content-Type: application/json' \
     --header 'X-API-Key: Your_API_Key'
     --data '
{
  "name": "PartnerCo",
  "metadata": {
    "internal_id": "123"
  }
}
'
