Question

//rest of code


//flow
      let message= {
        name: "lzgoflow",
        language: "en_US",
        category: "MARKETING",
        components: [
          {
            type: "body",
            text: "hello there",
          },
          {
            type: "BUTTONS",
            buttons: [
              {
                type: "FLOW",
                text: "lzgo",
                flow_id: 937561724890552,
                navigate_screen: "lzgo flow",
                flow_action: "navigate",
              },
            ],
          },
        ],
      };

      axios({
        method: "POST",
        url:
          "https://graph.facebook.com/v12.0/" +
          phone_number_id +
          "/messages?access_token=" +
          token,
        data: message,
        headers: { "Content-Type": "application/json" },
      })
        .then((response) => {
          console.log("Message sent successfully:", response.data);
        })
        .catch((error) => {
          console.error("Error sending message:", error.message);
        });
    }
    res.sendStatus(200);
  } else {
    res.sendStatus(404);
  }
});

This is my node.js code that request sending WhatsApp flows message, but every time I run it it gives me this error

Error sending message: Request failed with status code 400

I checked all the details (flow id, name and language code) it is all the same but it still gives me that error.

I think you have mixed the two API calls mentioned in the documentation. Seems like the message variable you have used is building request body for Creating a template but the Post call URL you are sending is for sending the template as in the example here.
