• list_numbers

  List the phone numbers on the user's ExpressNumber account that are live or being set up: id, the number in E.164 form, label, area code, mode (forwarding, blocked or texts_only), status and when it was created. Read-only.

• get_latest_messages

  Read the newest text messages received on the user's numbers, newest first. Each has the time received, which number got it, the sender, the text and a code field (digits pulled from the text, or null). Only the user's own numbers are ever read. The message text is written by out

• get_new_number
