# Counterpart addresses

> Add, update, and manage multiple addresses for counterparts representing vendors or suppliers via the Tesouro API.

## Overview

[Counterparts](/finops/guides/common/counterparts/index) that represent an [organization's](/finops/guides/organizations/index) vendors or suppliers must have their address information associated with them. Tesouro allows you to create multiple addresses for a counterpart.

## Add an address to a counterpart

To add an address to a counterpart, call `POST /counterparts/{counterpart_id}/addresses`:

```sh lines theme={null}
curl -X POST 'https://api.sandbox.tesouro.com/v1/counterparts/{counterpart_id}/addresses' \
     -H 'X-Finops-Version: 2025-06-23' \
     -H 'X-Organization-Id: ORGANIZATION_ID' \
     -H 'Authorization: Bearer ACCESS_TOKEN' \
     -H 'Content-Type: application/json' \
     -d '{
       "country": "US",
       "city": "Austin",
       "postal_code": "78701",
       "state": "TX",
       "line1": "123 Congress Ave",
       "line2": "Suite 100"
     }'
```

The successful response returns the information about the address including the ID:

```json lines theme={null}
{
  "country": "US",
  "city": "Austin",
  "postal_code": "78701",
  "state": "TX",
  "line1": "123 Congress Ave",
  "line2": "Suite 100",
  "id": "3fa85f64-5717-4562-b3fc-2c963f66afa6",
  "counterpart_id": "3fa85f64-5717-4562-b3fc-2c963f66afa6"
}
```

After creating a new counterpart address, Tesouro stores all available counterpart addresses in array. You can also update the counterpart's default billing and shipping addresses using the counterpart address ID issued after creating a counterpart. For more information, see [Edit a counterpart](#edit).

<Tip>
  Counterparts can use the same counterpart address for the `default_shipping_address_id` and
  `default_billing_address_id` fields.
</Tip>

## List all addresses

To get information about all addresses associated with the specified counterpart, call\
`GET /counterparts/{counterpart_id}/addresses` as shown:

```sh lines theme={null}
curl -X GET 'https://api.sandbox.tesouro.com/v1/counterparts/{counterpart_id}/addresses' \
     -H 'X-Finops-Version: 2025-06-23' \
     -H 'X-Organization-Id: ORGANIZATION_ID' \
     -H 'Authorization: Bearer ACCESS_TOKEN' \
```

The successful response returns an array of all counterpart addresses.

## Retrieve an address

To get information about a specific address associated with the specified counterpart, call\
`GET /counterparts/{counterpart_id}/addresses/{address_id}`.

## Edit an address

To edit an existing address of the specified counterpart, call\
`PATCH /counterparts/{counterpart_id}/addresses/{address_id}`.

## Delete an address

Only non-default addresses can be deleted. To delete an existing address from the list of addresses associated with the specified counterpart, call\
`DELETE /counterparts/{counterpart_id}/addresses/{addresses_id}`.

<Warning>
  The default billing and shipping addresses of a counterpart cannot be deleted. Attempts to delete
  these addresses will return an error.
