How to Create Trigger Call Custom Trigger Using C# Code in D365

Creating a custom trigger in Dynamics 365 Marketing's real-time journeys enables you to respond instantly to specific customer actions or events, enhancing engagement and personalization. Here's a step-by-step guide to creating and integrating a custom trigger.

We have 2 triggers

Custom Trigger
Record-Related Trigger

1. Custom Trigger

A custom trigger is a manually created event that is fired when an external system, app, or process sends a signal to Dynamics 365.

Key Features

Used for external events (e.g., website visits, form submissions, app interactions).
Requires an external system (such as Power Automate or an API call) to send data to D365.
Can include custom attributes (e.g., event name, location, time).
Provides more flexibility in defining the conditions that trigger the journey.

Example Use Cases

A customer logs into a mobile app, triggering a welcome journey.
A user subscribes to a newsletter via an external website.
A lead scans a QR code at an event.

2. Record-Related Trigger

A record-related trigger is automatically triggered when a specific Dataverse record (e.g., Contact, Lead, Opportunity) is created or updated.

Key Features

Used for internal CRM-based events (e.g., contact updates, case creation).
Works without external systems—it triggers based on Dataverse changes.
Can only track changes for one table (entity) at a time.
More structured—good for standard CRM workflows.

Example Use Cases

A new lead is created in D365, triggering a follow-up email.
A customer case status changes to “Resolved,” triggering a feedback survey.
An opportunity is marked as ‘Won’, starting a thank-you email journey.
