[question]: External ID example doesn't seem to be working

[EsinShadrach]

How can we help?

How do I target a specific user? I presently have a basic example to send a push notif to a set of users via the external ID but it send to like all the device, cause I know the device I'm on has an external ID of "5"

const options = {
  method: "POST",
  headers: {
    accept: "application/json",
    Authorization: `Key ${apiKey}`,
    "content-type": "application/json",
  },
  body: JSON.stringify({
    app_id: appId,
    // for grouping notifs
    collapse_id: "fixture_id_here",
    headings: { en: "Hello from Backend" },
    contents: { en: "Your message body here." },
    included_segments: ["Total Subscriptions"],
    target_channel: "push",
    include_aliases: {
      external_id: ["user1", "user2", "user3"],
    },
  }),
};

fetch(url, options)
  .then((res) => res.json())
  .then((json) => console.log(json))
  .catch((err) => console.error(err));

Hi @EsinShadrach thanks for reaching out with your question. Our REST API documentation for sending messages and notifications is here.

I see you have included_segments: ["Total Subscriptions"] which is why this notification is sent to all devices. You should remove this and only keep the following for your target audience:

target_channel: "push",
include_aliases: {
    external_id: ["user1", "user2", "user3"],
}
