Telnyx

What This Integration Enables

Telnyx is carrier-grade messaging infrastructure, and the thing that separates disciplined SMS operations from expensive noise is what happens before and after the send. FlowRunner agents use Telnyx the way a careful operator would: look the number up first, send with the right sender identity, then verify the message actually arrived and what it cost. Because Number Lookup is a read-only intelligence call, agents can qualify every phone number that enters your workflows without spending a message segment on a dead line. - Send transactional SMS and MMS from a Telnyx number, short code, or alphanumeric sender ID - Validate numbers and detect line type, carrier, and portability before messaging - Check delivery status, encoding, and per-recipient cost on any sent message - Search purchasable inventory by country, area code, and required features - Audit the numbers and Messaging Profiles configured in your account The number inventory operations round out the picture for teams that treat their sender identities as assets. Search Available Numbers lets an agent scout purchasable inventory by market and required features when a new region or campaign needs local presence, and because it is search-only, the agent can present options without ever committing spend. List Phone Numbers and Get Phone Number keep the audit side honest: which numbers you own, which Messaging Profile each rides on, and whether the configuration behind a workflow still matches what the workflow assumes. Text messages land in pockets, which is exactly why FlowRunner's [human-in-the-loop](/concepts/human-in-the-loop) gate sits in front of anything beyond routine transactional sends. The pattern is consistent across every messaging connector FlowRunner offers, but the mechanics here are Telnyx's own: lookups before sends, statuses after them, and a person in between whenever the audience is a list rather than a customer.
