queued: true means saved and waiting in the queue, not delivered. The message_id in the response is provisional: the real SMTP Message-ID replaces it a few seconds later and shows up in get_messages.

Quick start

import axios from 'axios';

const response = await axios.post(
  'https://g.sendcorex.com/v1',
  {
    commands: [
      {
        command: "send_email",
        args: {
          to: "client@example.com",
          to_name: "Client",
          subject: "Quote",
          html: "<p>Here is the quote.</p>",
          label: "sales"
        }
      }
    ]
  },
  { headers: { Authorization: process.env.SENDCOREX_TOKEN } },
);

const [result] = response.data.results;
if (result.type !== 'SUCCESS') throw new Error(`${result.code}: ${result.message}`);
console.log(result.data);

Response

{
  "type": "SUCCESS",
  "results": [
    {
      "command": "send_email",
      "id": "0",
      "type": "SUCCESS",
      "data": {
        "message_uid": "Vj0xQUJDMTIz",
        "thread_id": "thr_9a1c4e72",
        "message_id": "<5e0b9c1a-3d7f-4a21-9a6e-2f1c8d4b7e90>",
        "queued": true
      }
    }
  ]
}

Response fields

The id of the sent message. It appears in Sent immediately.
thread_id

Repeated sends

The same write (same args) repeated within 1.5 seconds returns the first result instead of sending again. A polling loop that sends the same email twice does not duplicate it.
