POST/v1/crossborder/clients/:client_id/counterparties
Create a new crossborder counterparty for a specific client. The counterparty will be associated with the specified client and user.
Request
Path Parameters
Unique identifier (UUID) of the client that will own this counterparty.
Header Parameters
- If there's no value: The default protection checks that the values in this request are equal: { method, params, path, query, body, userId }. This means that if a request repeats the same values, it will be blocked.
- 'nonce': The nonce and { method, params, path, query, body, userId } value are checked. When the protection schema is this, requests will be OK if this nonce value is different in each request.
- 'x-transaction-uuid': The transactionId and { method, params, path, query, body, userId } value are checked. Requests will be OK if this x-transaction-uuid value is different in each request.
- 'x-transaction-uuid&nonce' or 'nonce&x-transaction-uuid': The nonce, transactionId value and { method, params, path, query, body, userId } are checked, i.e. if requests are repeated the same value in both fields, they will be blocked. But if any field has a different value, the request is OK.
The replay-protection-schema allows the user to choose between 3 options:
The transaction ID is a UUID (v4) used to uniquely identify the object that will be created. All objects must have an identifier.
The nonce ID is a UUID (v4) used to uniquely identify the request. All requests must have an identifier.
Possible values: [pt-BR, en-US]
Indicates the preferred language. Defaults to Brazilian Portuguese if unspecified.
The product ID is a UUID (v4) used to identify the Z.ro product configuration.
The product target user ID is a UUID (v4) used to identify what user account this request must be executed. Require: x-product-uuid.
