Update calling config
Deprecated alias of /v1/phone-numbers/{id}/whatsapp/calling; same contract. New
integrations should use that path.
Update fields on an already-enabled number. Only fields present in
the body are written; undefined leaves the stored value alone,
explicit null clears a nullable field. No Meta side effect, this
only changes local routing state consumed by the Telnyx webhook
handler.

}Set business username POST
Claim or transfer a WhatsApp Business username for the account. Username rules: 3-35 characters, letters/digits/period/underscore only, must contain at least one letter, no leading or trailing periods, no consecutive periods, no `www` prefix, no domain TLD suffix (e.g. `.com`). If the desired username is currently held by another account, pass `transferAction: "force_transfer"` to request a transfer. On failure the API returns a standard error envelope with one of these codes: `whatsapp_username_unavailable` (already taken and transfer not requested), `whatsapp_username_ineligible` (account not eligible to claim a username), or `whatsapp_username_transfer_required` (username is held elsewhere; retry with `force_transfer`).
