# Buy Telnyx Number

`POST /api/channels/telnyx/numbers/buy`

## Request

- Base URL: `https://api.dialogbrain.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api.dialogbrain.com/api/channels/telnyx/numbers/buy`
- Auth: none declared

Order a number.

Regulated countries (Thailand among them) require identity documents
before the order activates. Telnyx returns that as an error, which we
pass through verbatim — a generic failure would leave the user with no
idea that paperwork is what is missing.

  - `api_key` string, required: Telnyx API v2 key
  - `phone_number` string, required
