"For TUI Musement, Airbyte cut development time in half and enabled dynamic customer experiences."

“Airbyte helped us accelerate our progress by years, compared to our competitors. We don’t need to worry about connectors and focus on creating value for our users instead of building infrastructure. That’s priceless. The time and energy saved allows us to disrupt and grow faster.”

Rupak Patel
"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."
First, obtain API access for your Postmark account. Log into your Postmark account, navigate to the "Server" you want to work with, and find the "API Token" under the "API" section. This token will allow you to authenticate your requests to the Postmark API.
Use the Postmark API to retrieve the data you need. You can do this by making HTTP GET requests to specific endpoints available in the Postmark API, such as messages or statistics. Use tools like `curl` or create a script in a language like Python to automate this task. Ensure you handle pagination if there is a large volume of data.
Once you have fetched the data, process it as needed. This might involve parsing JSON responses, extracting specific fields, or converting the data into a CSV or JSON file format for easier storage. This step is essential to ensure that the data is in a suitable format for upload to S3.
Log in to your AWS Management Console and navigate to S3. Create a new bucket or use an existing one to store your data. Make note of the bucket name and the desired path within the bucket where you want to store your data files.
Install and configure the AWS Command Line Interface (CLI) on your machine if you haven't already. Use the command `aws configure` to set up your credentials (AWS Access Key ID, Secret Access Key, region, and output format). This configuration allows you to interact with AWS services from your command line.
Use the AWS CLI to upload the processed data files to your S3 bucket. The command will look something like `aws s3 cp your_file.json s3://your-bucket-name/path/`. Ensure you have the necessary permissions to write to the S3 bucket from your AWS account.
After the upload, verify the integrity of the data in S3. You can do this by checking the S3 bucket through the AWS Management Console or using the AWS CLI to list the files in the bucket. Optionally, download a file and compare it with the local version to ensure it has been uploaded correctly.
This guide provides a straightforward approach to moving data from Postmark to S3 using direct API calls and AWS tools, ensuring you maintain full control over the process without relying on third-party services.
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.
