SDKs & client libraries
Use the HTTP client you already know. You can call mintfax from any language; the API uses REST and JSON, with multipart file uploads when you send a fax. There are no official mintfax SDK packages.
Examples
| Language | HTTP client | Guide |
|---|---|---|
| Node.js | Native fetch | Node.js guide |
| Shell | curl | Quickstart |
The Node.js example uses native fetch and verifies webhooks with node:crypto, so even the signature check uses the standard library. Both guides call the API directly.
Generate a client
The OpenAPI 3.1 specification describes the endpoints, parameters, and response formats. You can use a generator that supports OpenAPI 3.1 to create a client for your language.
Get started
Follow the quickstart to register, verify your email, and send a sandbox fax. See authentication for sandbox and live API keys.
