To debug the issue, I have two suggestions for you:

• please check whether the API expects the word "Token" before the actual token. Some APIs expect "Bearer" before the actual token. {.header("Authorization", "Bearer d2618176b9b9aed6dc0a9cb3a1ebfe1c4c8831ed999bdce4432e061aa56f672f")}

• Log your request by enabling logging ( log().all()) in rest assured to debug your request and verify that the headers and body are being sent correctly. Resource
