Welcome to the Courier Documentation

Courier lets you design your notifications once and deliver them to any channel-push notifications, direct messages, SMS, and email-with a single [Courier API](/reference/intro) rather than having to integrate each provider API separately.

What is Courier?

Courier terms and concepts you will commonly see when you use Courier's notification platform.

Courier Users

Courier uses the term `user` to describe the recipient of a notification.

Users

There are two ways that developers can construct the content of the notifications that they send:

Introduction

Content

The Asset Manager is a new way to organize assets in Courier. The Asset Manager can be used to organize your automation, message, and shared content templates.

The Channel Settings contain important configurations that allow you to define if and when the Channel will send to users or be disabled. You can also add integrations and order the send priority when there are multiple integrations in a channel. Channel and integration-specific settings are here as well.

Channel Settings

Send Priority Rules

Courier's business tier customers get access to Send Limits, which lets you set upper limits on the number of messages that can be sent per time period.

Send Limits

Courier employs a robust retry mechanism to ensure reliable notification/webhook delivery and accurate status tracking, even in the event of temporary downstream failures or network issues.

Delivery Pipeline Resilience

This feature aimed to make digests straightforward to configure and implement for our customers without requiring code changes when moving from a frequent transactional message to an aggregated message based on a schedule.

Digesting a Send API

Use automated failover to provide resiliency against potential issues that could prevent a notification from being delivered.

Automated Failover

As part of a Send in Courier, you can define the time to wait before delivering the message and Courier will handle. Courier supports one of three ways to delay

Courier Preferences gives your users the ability to control which notification topics they receive, through the channels of their choice. This feature is designed to give your users control over their communication preferences and to help you comply with data privacy regulations like GDPR and CCPA.

Tenants are a flexible hierarchical database object meant for collecting groups of users and metadata belonging to the user group.

Tenants

Sending With Tenants

When you send a notification to the Courier Inbox with a tenant context, you send the notification to a separate inbox that is only accessible when the `tenantId` is configured.

Inbox and Tenants

User Preferences in Courier can be further refined by using Tenants. For example, if a user belongs to two tenants, the user can choose to opt out of one tenant's topic and opt in to the other.

User Tenant Preferences

Automations is a powerful notifications orchestration service. It allows anyone to easily design smart notification delivery workflows, without having to code anything.

Automations v3

The automations designer is a node-flow based visual programming environment designed for all technical skill levels.

Designer

The Automations Designer

All fields within the designer or an adhoc automation can be pointed to dynamic data using a special `refs` object syntax.

Dynamic Data

Accessing Dynamic Data

Automations Designer supports a variety of methods to trigger an automation. Courier ingests inbound events such as tracking or user identify, and persists them such that they can later get used as a trigger.

Inbound Event Triggers

One of the most common use cases for automations is hooking up notifications to segment events.

Segment

Often times you may want to cancel an automation run. For example, one automation may send out a reminder notification to complete a task. However, this reminder may no longer be necessary if the task is already completed. 

Cancelling

Cancelling An Automation

Automations can conditionally execute a branch of the workflow. This can be useful in any case where you may want to change the actions of an automation based on certain data sent with the template.

Control Flow

Conditional Control Flow

Scheduling is a feature of Automations that enables scheduling of a notification automation via three methods

Scheduling

Courier Automations can be leveraged to create recurring user digests on configured intervals. This can be useful for things like weekly reports or user digests, while also offering user schedule preferences if desired.

Digests

Courier's business tier customers have access to Webhook Triggers in Automations. Webhook Triggers enable you to connect other products and systems to Courier and trigger Automations based on events that happen in those systems. You have the full context of the webhook event payload and can use this data within the automation to send notifications, update profiles, or run workflows using Automation steps. This guide will walk you through how to register an inbound webhook and set up a Webhook Trigger.

Webhook Trigger

Batching is an Automations feature that aggregates events and consolidates multiple notifications into a single update.

Batching

The Throttle feature in Automations restricts the number of events that can trigger notification automations.

Throttle Node

Ad hoc automations can be defined and invoked in a single API call, without needing to create a full automation template. This document outlines the various types of steps you can use in an ad hoc automation run.

Ad hoc Automation Steps

The GET Profile node will attach the profile of the provided user id to the automation context. This allows you to use the profile data in subsequent nodes.

GET Profile

Courier Inbox is a set of APIs and SDKs that make it easy to add a modern notification inbox to your web or mobile application.

Inbox Push Notifications

In order to send notifications to Inbox, you need to [log-in](https://app.courier.com/login) to your Courier account and install the [Courier Provider](https://app.courier.com/channels/courier). Once you've done that, make note of the Client Key. You'll need that value to initialize the Inbox SDK.

Installing the Provider

Installing the Inbox Provider

When you're ready to [send a message](/docs/reference/send/message), it's exactly like sending any other Courier notification, with the difference being that you are sending it to the `inbox` channel.

Making an Inbox Send

Sending a Courier Inbox Message

Instead of defining the content of the entire notification in-line, you can leverage Templates to send a message.

Courier Inbox supports the retrieval and display of different messages, filtered by parameters.

You can invite teammates to your workspace, require them to login via Google SSO, and choose to make your workspace discoverable to teammates who sign up on their own using your verified email domain.

Workspace Security Settings

When you have a long list of notifications, adding tags allows you to search and filter your list of Notifications by multiple, custom parameters in addition to Name and Channel.
