Purchase a dedicated IP

Purchase a dedicated sending IP. Requires a verified, enterprise, or legacy account, and an Idempotency-Key header: a request without the header returns 400 (code 10015) and allocates nothing. Telnyx allocates the next available IP from stock. The optional region and ip_version fields each restrict which stock IP is allocated; they never change the allocated IP’s metadata. An omitted field applies no restriction for that field, and omitting the body applies neither restriction. An unsupported selector value returns 422; a supported value that matches no available IP returns 429 and records the request on the waitlist. Billing: $14/month/IP, charged as a monthly recurring charge (MRC) from purchase. The IP is returned in provisioning status with a Telnyx-managed PTR hostname and carries no mail until you call start_warmup and add it to a pool that routes mail.

Authorizations

Authorization

string

header

required

Telnyx API key supplied as Authorization: Bearer <token>. In production, auth may be validated by the API gateway and forwarded via Telnyx auth headers.

Headers

Idempotency-Key

string

required

Required. Opaque, unquoted key for safely retrying the same purchase. Keys must contain 1 to 255 letters, numbers, hyphens, or underscores. Generate a unique UUID v4 for each purchase and reuse it only when retrying that purchase with the same request. A missing header, or an invalid one —including duplicate, empty, malformed, or overlong values—returns 400 with error code 10015. A request already in progress with the same key returns 409; reusing the key with a different request returns 422. Only successful responses are replayed, for up to 24 hours. Do not include sensitive data in the key.

Required string length: 1 - 255

Pattern: ^[A-Za-z0-9_-]{1,255}$

Body

application/json

Optional purchase selectors. Each supplied field restricts which stock IP is allocated; neither field is written to the IP. Omit the body or a field to apply no restriction for it. Other fields are ignored.

region

enum<string>

Allocate an IP in this region. Supported value: ewr-nj1. Any other value, including an empty string or null, returns 422.

Available options:

ewr-nj1

ip_version

enum<string>

Allocate an IP of this address family. Supported value: ipv4. Any other value, including ipv6 or null, returns 422.

Available options:

ipv4

Response

Dedicated IP allocated

data

object

required

A dedicated sending IP address owned by the account.
