Firstname and phone request

[ehssanehs]

Hi
I used javascript code on my html webapp to use magicbell.
I used useexternalid and useremail and it works well.
But my problem is what fields to fill to get first name and last name and phone?

Hey @ehssanehs welcome to the community! You can send them in the create broadcast call in the recipients attributes, or you can call our users endpoints to update them asynchronously whenever you have new data on the users. For example, here is the sample JSON from the |API reference](https://www.magicbell.com/docs/rest-api/reference#broadcasts-create)

{
  "broadcast": {
    "title": "We're processing your order",
    "content": "<p>Thank you for your order. We'll notify you when these items are ready.</p>",
    "category": "order_created",
    "topic": "order:33098",
    "recipients": [
      {
        "email": "[email protected]"
      },
      {
        "external_id": "83d987a-83fd034",
        "first_name": "Person",
        "last_name": "Doe",
        "custom_attributes": {
          "plan": "enterprise",
          "pricing_version": "v10",
          "preferred_pronoun": "They"
        },
        "phone_numbers": [
          "+1 5005550001"
        ]
      }
    ],
    "overrides": {
      "channels": {
        "email": {
          "title": "[MagicBell] We're processing your order",
          "content": "Thank you for your order. If you need help, or have any questions please don't hesitate to reach out to us directly at [email protected]"
        }
      }
    }
  }
