What Telnyx (BYOK) is for

Telnyx (BYOK) lets an AI assistant read your own Telnyx data through the Telnyx API with a key you supply (API key (V2)). Read-only: 8 tools (get_balance, list_phone_numbers, list_messaging_profiles, get_message, list_connections, list_outbound_voice_profiles, list_recordings, list_call_control_applications). The BYOK key travels with each request, is used for that one call only and is never stored, logged or cached; it is only ever sent to api.telnyx.com. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Telnyx. Telnyx and its logos are trademarks of their owners and are used only to say which service the connector works with.

Ask your assistant things like:

• "How much balance do I have left on Telnyx?"
• "Which phone numbers do I own on Telnyx and are they active?"
• "What messaging profiles are set up in Telnyx?"
• "Was this Telnyx text message delivered?"
• "Which Telnyx voice connections are active?"
• "What spend limits do my Telnyx outbound voice profiles have?"

What it does

• get_balance: Show the account balance, available credit, credit limit, pending charges and currency.
• list_phone_numbers: List the account's phone numbers with status, type, country, connection, messaging profile and feature flags. Optional filters on status and number.
• list_messaging_profiles: List messaging profiles with name, enabled flag, daily spend limit, sender settings and timestamps.
• get_message: Get one SMS/MMS message record by ID: direction, type, sender, recipients with delivery status, text, parts, cost, timestamps and errors.
• list_connections: List voice connections (SIP trunks and apps) with name, active flag, webhook version and outbound voice profile.
• list_outbound_voice_profiles: List outbound voice profiles with daily spend limit, concurrent call limit, destination rate cap and enabled flag.
• list_recordings: List call recordings with caller, callee, duration, start and end time and status (download links are not returned).
• list_call_control_applications: List call control applications with name, active flag, webhook version and channel limits.

BYOK key

You bring your own Telnyx API key (V2) (https://portal.telnyx.com/#/api-keys). Your assistant sends it in the X-Upstream-Key header with each request. ConnectorBay uses it for that one call only: it is never stored, logged or cached, never shown in an answer, and it is only sent to api.telnyx.com over https, with no redirects followed. Create a key with the fewest permissions the tools need (read-only if the provider offers it), and revoke it at the provider whenever you like.

Telnyx (BYOK) — Privacy Policy

Effective 24 October 2026. Unify Dynamics LLC ("we", "us"), Menlo Park, California.

What Telnyx (BYOK) is. Telnyx (BYOK) is a connector (an MCP server and REST API) that an AI assistant calls on your behalf to read your own Telnyx data: Read your Telnyx balance, phone numbers, messaging profiles, message records, voice connections and call recordings with BYOK. You bring your own Telnyx API key (V2); the assistant sends it to us with each request.

BYOK key. The key you supply is used to make the one Telnyx call you asked for. Our application does not store it, write it to a log, put it in a cache, or share it. It is sent only to api.telnyx.com, over https, and is removed from any text we return to you or your assistant. We do not follow redirects with your key. If Telnyx rejects it, we say so without repeating it.

What we receive. The arguments of each tool call, the BYOK key (for that call only), the technical headers needed to serve the request (an IP address or a client identifier supplied by the assistant) and standard server logs. What Telnyx receives. The request we make on your behalf, including the key and the arguments, under Telnyx's own terms and privacy policy. Telnyx acts at your direction and is the only recipient of the data of your request besides our hosting provider.

What we return. The answer Telnyx gives for your request, trimmed to the fields the tool documents. We do not keep it: it is returned to your assistant and not stored, cached or used to train anything.

What we do not do. We do not build a profile, sell or share personal information, or keep your Telnyx data. Rate-limit counters (a client identifier and timestamps) are held in memory for at most 24 hours. Hosting access logs (IP addresses, request paths and status codes) are kept for up to 30 days for security and abuse prevention; our application adds no request headers or bodies to them.

Sub-processors. Telnyx (the API you call with a BYOK key, at your direction). Hosting: Vercel (United States regions).

Your rights. Because we store no personal data beyond short-lived logs, requests to access, correct or delete data are usually satisfied automatically; you can still contact agent@connectorbay.com and we will respond within 30 days. Revoke your key at Telnyx at any time to end all access.

Children. Telnyx (BYOK) is a general-audience service operated by the adult using the assistant, under Telnyx's own age rules.

Changes. We will post changes here with a new effective date.
