"With Airbyte, we could just push a few buttons, allow API access, and bring all the data into Google BigQuery. By blending all the different marketing data sources, we can gain valuable insights."
Postmark allows you to create webhooks to send event data to a specified URL whenever an email-related event occurs. Start by logging into your Postmark account. Navigate to the "Servers" section, select your server, and then go to the "Webhooks" tab. Configure a webhook to capture the event types you are interested in (such as email bounces, deliveries, opens, etc.) and specify the URL of your intermediary server that will process these events.
Set up a simple server to receive and process incoming webhook requests from Postmark. This can be done using a cloud provider (like AWS, Google Cloud, or any VPS) with a basic web server configuration. Use a technology stack you are comfortable with (such as Node.js, Python Flask, etc.) to create an endpoint that accepts HTTP POST requests from Postmark.
Once your server receives a webhook request from Postmark, it needs to parse the JSON payload. Ensure your server-side code is equipped to handle the data format sent by Postmark. Typically, this involves extracting relevant details about the email events from the JSON body.
To interact with Google Pub/Sub, your server needs to authenticate with Google Cloud Platform (GCP). Set up a service account in GCP and download its JSON key file. Your server will use this key to authenticate API calls to Google Pub/Sub. Ensure that the service account has the necessary permissions to publish messages to your Pub/Sub topic.
On your server, install the Google Cloud client library appropriate for your programming language. For instance, if you're using Node.js, you can install the `@google-cloud/pubsub` package. This library will provide the necessary methods to interface with Google Pub/Sub.
Using the client library, write code to publish the parsed data from the webhook to a specific Pub/Sub topic. Ensure that your server extracts the necessary information from the webhook payload and formats it correctly before sending it to Pub/Sub. Handle any potential exceptions or errors in the publishing process to ensure reliable data transfer.
After setting up the above components, test the entire flow by triggering events in Postmark that will send data to your intermediary server. Verify that the data is correctly received and processed, and that messages are successfully published to Google Pub/Sub. Implement logging on your server to monitor requests and responses, and consider setting up alerts for any failures or issues.
By following these steps, you can effectively move data from Postmark to Google Pub/Sub without using third-party connectors or integrations, ensuring a seamless and direct data flow.
FAQs
What is ETL?
ETL, an acronym for Extract, Transform, Load, is a vital data integration process. It involves extracting data from diverse sources, transforming it into a usable format, and loading it into a database, data warehouse or data lake. This process enables meaningful data analysis, enhancing business intelligence.

What is ELT?
ELT, standing for Extract, Load, Transform, is a modern take on the traditional ETL data integration process. In ELT, data is first extracted from various sources, loaded directly into a data warehouse, and then transformed. This approach enhances data processing speed, analytical flexibility and autonomy.
Difference between ETL and ELT?
ETL and ELT are critical data integration strategies with key differences. ETL (Extract, Transform, Load) transforms data before loading, ideal for structured data. In contrast, ELT (Extract, Load, Transform) loads data before transformation, perfect for processing large, diverse data sets in modern data warehouses. ELT is becoming the new standard as it offers a lot more flexibility and autonomy to data analysts.
