Request

Path Parameters

client_id stringrequired

Unique identifier (UUID) of the client that will own this counterparty.

Header Parameters

x-include-replay-protection-schema string

The replay-protection-schema allows the user to choose between 3 options:

• 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.

x-transaction-uuid stringrequired

The transaction ID is a UUID (v4) used to uniquely identify the object that will be created. All objects must have an identifier.

nonce stringrequired

The nonce ID is a UUID (v4) used to uniquely identify the request. All requests must have an identifier.

x-lang string

Possible values: [pt-BR, en-US]

Indicates the preferred language. Defaults to Brazilian Portuguese if unspecified.

x-product-uuid string

UUID (v4) of the product that the request should use. Send it explicitly when the authenticated user has more than one product or when the integration must select a specific product. If omitted and the endpoint does not require it, the API uses the authenticated user's default product.

x-product-target-user-uuid string

UUID (v4) of the user on whose behalf the request should run within the selected product. If omitted, the request runs as the authenticated user. Requires x-product-uuid.

x-wallet-uuid string

Sender Wallet UUID (if empty, your default Wallet UUID will be settled)
