There are various sources for your business to acquire data and use them for productive decision-making. One among those insightful sources is REST API. To centralize data and obtain in-depth data analytics benefits, you can migrate data to Amazon Aurora from REST APIs.

Amazon Aurora REST API integration might seem daunting, but it doesn’t require extensive resources or time. In this article, you will learn about the two popular Amazon Aurora REST API connection methods for seamless data transfer. Check them out, and decide which way seems feasible for your data integration.

How to Connect REST API to Amazon Aurora?

Here are two methods for you to seek REST API to Amazon Aurora migration easily:

  • Method 1: Custom Script Approach to Move Data From REST API to Amazon Aurora
  • Method 2: Using a No-Code Tool For Automated Data Replication from REST API to Amazon Aurora


  • Get an active Amazon Aurora account.
  • Ensure the Amazon Aurora MySQL Instance is active.
  • The MySQL versions should be 5.1 or higher.
  • Make Amazon Aurora’s port number and database hostname available.

Method 1: Custom Script Approach for Aurora REST API Connection

The custom script approach for REST API to Amazon Aurora migration is a three-step process:

  • Step 1: Using Python for Extraction of REST API data using JSON Format
  • Step 2: Upload the REST API data to Amazon S3 Bucket
  • Step 3: Upload the data to Amazon Aurora

Step 1: Use Python for Extraction of REST API Data using JSON Format

  • Use Python to establish a connection with the REST API endpoint to extract data. The code snippet to establish the connection with REST API would vary based on the applications or database you are trying to connect with. 
  • Typically, you will receive the data from REST API in a JSON format. 
  • Save the extracted data in the JSON format on your local device. 

Step 2: Upload the REST API Data to Amazon S3 Bucket

Proceed to upload the JSON file to an Amazon S3 bucket situated in the same region as the Aurora database. You can upload an object to S3 using the AWS CLI or S3 Console.

Using the S3 Console:

  • Sign in to AWS Management Console and open Amazon S3 service.
  • Create or select a bucket. If you don’t have a bucket, create one. Click on the Create bucket button. Choose a globally unique bucket name, and select the region. Configure additional settings as needed and click on Create bucket.
  • Inside your selected bucket, choose the destination folder and click the Upload button. Click the Add files button or drag-and-drop your JSON files into the dialog. You can also select multiple files to upload the data together.
  • Finally, click on Upload to start the uploading process.

Using AWS CLI:

  • Install AWS CLI and configure it by providing your AWS Access Key ID, Secret Access Key, default region, and output format.
  • Use the aws s3 cp command to upload the data to your S3 bucket:
aws s3 cp /path/restapidata.json s3://bucket-name/info.json

Replace /path/restapidata.json with the API data file path and bucket-name with your S3 bucket name. You can use aws s3 sync for uploading multiple files or syncing directories.

  • Log in to AWS Management Console, navigate to S3 service, and select your bucket. Verify that the uploaded data files are present in the bucket.

Step 3: Upload the Data to Amazon Aurora

Loading JSON files from Amazon S3 to Amazon Aurora involves the following steps:

  • Create an Amazon Aurora DB and Target Table: You can select an existing Aurora database or create a new one using AWS Management Console and Amazon RDS service. Then use a MySQL or PostgreSQL client to connect with your Aurora database.
  • Generate an AWS IAM Role for S3 Access: To allow Aurora to access the JSON file stored in S3, establish an AWS Identity and Access Management (IAM) role. Ensure that the IAM role has appropriate permissions (e.g., AmazonS3ReadOnlyAccess) to access the S3 bucket and the JSON file.
  • Load JSON Files from S3 to Amazon Aurora: There are several ways and tools available that help you to load data from S3 to Amazon Aurora. It could include using SQL or PostgreSQL client, AWS Database Migration Service, or AWS Glue. Here’s an example of loading the data using an SQL client.

Execute LOAD DATA FROM S3 SQL statement to import the JSON data into your Amazon Aurora tables.

LOAD DATA FROM S3 's3://bucket-name/path/to/json-files/' 
INTO TABLE table_name 

Replace the syntax with the actual bucket name, file path, table name, and JSON column name.

These steps will help you manually migrate the REST API data to Amazon Aurora.

This method is beneficial in the following scenarios:

  • Optimizing Data Performance: Building custom scripts for migrating data allows you to enhance the performance of specific datasets. Custom scripts help you with data compression, data partitioning, and selective data migration for added optimization. It results in reduced downtime, faster transfer of data, and better resource utilization regardless of the type of integration you perform. 
  • Proper Data Validation: Using custom scripts helps you run data validation checks to find outliers and remove any duplicates during the transfer process. With this, you can confirm data consistency, run integrity checks, and test the data mappings. It enhances the quality of data for better insights. 
  • Flexibility: By using custom scripts, you obtain complete control of the data integration process. You can modify your scripts to meet tailored requirements, such as data format transformations and data enrichment before it is loaded onto the destination. 

Here are some limitations to using the custom script approach for migrating data to Amazon Aurora from REST API:

  • Complex Maintenance Issues: If you always prefer using custom scripts for moving data from REST API to Amazon Aurora, it will require consistent updates and maintenance. Every time the data format changes, you must modify the script as well to make it compatible. It might be a time-consuming process when you have to migrate data through this method regularly. 
  • Data Security Hassles: It might be difficult for custom scripts to handle authorization, authentication, and secured data transmission. As a result, data migration might be vulnerable. This could lead to unauthorized access to sensitive data.  
  • Time and Resource Consuming: Preparing custom scripts consumes a lot of time and effort. It might take a few days or even weeks to build the data pipelines, which might not be efficient for business productivity.  

Method 2: Using a No-Code Tool For Automating the Data Migration Process

The limitations of a custom scripting approach might hinder your business performance. To overcome these hassles, you can embrace a no-code ETL tool. Some perks of using a no-code tool include:

  • Widened Connectivity of Data Sources: No-code tools can integrate with SaaS systems, SDKs, cloud storage, streaming services, and databases for analyzing data in various formats. 
  • Saves Time & Effort: The no-code ETL connectors help in moving data from any siloed source to a unified data warehouse in just a few steps. You don’t have to use coding to build the data pipelines from scratch.
