Common Setup

Authentication

Postmark uses two types of API tokens:

Token	Header	Scope
Server Token	`X-Postmark-Server-Token`	Sending emails, templates, bounces, webhooks, message streams
Account Token	`X-Postmark-Account-Token`	Managing servers, domains, sender signatures

Get your Server API Token from Postmark Servers.

SDK Installation

Detect the project language and install the appropriate SDK:

File	Language	Install Command
`package.json`	Node.js / TypeScript	`npm install postmark`
`requirements.txt` / `pyproject.toml`	Python	`pip install postmarker`
`Gemfile`	Ruby	`gem install postmark`
`composer.json`	PHP	`composer require wildbit/postmark-php`
`.csproj` / `.sln`	.NET	`dotnet add package Postmark`

Message Streams

Postmark separates email by intent into Message Streams:

Stream	Value	Purpose
Transactional	`outbound`	1:1 triggered emails (welcome, password reset, receipts) — default
Broadcast	`broadcast`	Marketing, newsletters, announcements

Never mix transactional and broadcast email in the same stream — it damages deliverability.
