Sinch Porting API

Overview

The Porting API automates port-in operations — transferring phone numbers from another carrier into Sinch. It supports portability checks, order creation and management, document uploads, on-demand activation, and webhook notifications for status updates. Currently supports North American (US/CA) numbers only.

Agent Instructions

Before generating code, gather from the user (skip any item already specified in the prompt or context):

1. Use case — portability check, create order, track order, or activate numbers?
2. Activation mode (only for create order) — Automatic (on desiredPortDate) or on-demand (onDemandActivation: true)?
3. Language — any language, or curl. The @sinch/sdk-core Node.js SDK does not currently have dedicated porting methods — use direct HTTP for all porting operations.

Refer to the API reference linked in Links for request/response schemas.

Security: See the Security section below for url fetching policy, handling inbound webhook content, and credential handling.
