# List WhatsApp numbers

> Connected WhatsApp numbers, oldest first. Unpaginated: an org has a
handful of lines, not a page of them.



## OpenAPI

````yaml /api-reference/openapi.json get /v1/channels/whatsapp/phones
openapi: 3.1.0
info:
  title: Ciarem API
  version: v1
  description: >
    The Ciarem public API. Authenticate every request with an org-bound API key

    (created in Settings → API keys; Scale plan or free trial) sent as a bearer
    token:

    `Authorization: Bearer oak_…`.


    Compatibility: this is an early, fast-moving API. Most changes are

    additive (new endpoints, new optional params, new response fields, new

    enum/string values) — clients must tolerate unknown fields and unknown

    string values. Every contract change is listed in the changelog at

    help.ciarem.ai.
