Sinch Fax API
Overview
The Sinch Fax API lets you send and receive faxes programmatically. It supports multiple file formats, webhooks for incoming faxes, fax-to-email delivery, and automatic retries. Used for healthcare, legal, financial, and government applications where fax remains a required communication channel.
Agent Instructions
Before generating code, gather from the user (skip any item already specified in the prompt or context):
- Use case — sending, receiving, fax-to-email, or managing services?
- Approach — SDK or direct API calls (curl/fetch/requests)?
- Language — for SDK: Node.js (preview) or .NET (partial). For direct API: any language, or curl. Java and Python must use direct HTTP — there is no SDK wrapper.
When the user chooses SDK, refer to the sinch-sdks skill for installation and client initialization, then to the Fax API Reference linked in Links.
When the user chooses direct API calls, refer to the Fax 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.
