SendGrid Webhooks
To integrate SendGrid webhooks with ngrok:
This guide covers how to use ngrok to integrate your localhost app with SendGrid by using Webhooks. SendGrid webhooks can be used to notify an external application with information about events that occur as SendGrid processes your email.
By integrating ngrok with SendGrid, you can:
- Develop and test SendGrid webhooks locally, eliminating the time in deploying your development code to a public environment and setting it up in HTTPS.
- Inspect and troubleshoot requests from SendGrid in real-time via the inspection UI and API.
- Modify and Replay SendGrid Webhook requests with a single click and without spending time reproducing events manually in your SendGrid account.
- Secure your app with SendGrid validation provided by ngrok. Invalid requests are blocked by ngrok before reaching your app.
Step 1: Start your app
For this tutorial, we'll use the sample NodeJS app available on GitHub.
To install this sample, run the following commands in a terminal:
Loading…
This will get the project installed locally.
Now you can launch the app by running the following command:
Loading…
The app runs by default on port 3000.
You can validate that the app is up and running by visiting http://localhost:3000. The application logs request headers and body in the terminal and responds with a message in the browser.
