For constraints and rules regarding documents that can be attached as part of the message, see <a href="/docs/integration/direct/customer-disputes/integration-guide/#documents">documents</a>. To send a message, use the <code>send-message</code> link in the <a href="/docs/api/reference/api-responses/#hateoas-links/">HATEOAS links</a> of the <a href="/docs/api/customer-disputes/v1/#disputes_get">show dispute details</a> response and specify the message in the JSON request body. In case the link is not present in the response you can't send a message on the dispute.
