Connecting to Data Sources

Rich applications require real data to build intuitive UI, perform data transformations & write business correct logic. Appsmith can talk to your data in the following ways

Before connecting to a data source, you must whitelist the IP address of the Appsmith deployment on your database instance or VPC and are the IP addresses of the Appsmith cloud instances that need to be whitelisted

This is a guide on how to whitelist appsmith on AWS.


Appsmith safely encrypts all your data source credentials and stores them securely. Appsmith also does not store any data returned from your data sources and acts only as a proxy layer to orchestrate the API / Query calls. Since Appsmith is an open-source framework, you can deploy it on-premise, and audit it to ensure none of your data leaves your VPC.

Mock Data

If you would like to play around with the platform before connecting your data, we provide mock data sources that you can use.

Mock DB

Every personal organization comes with a mock database for you to query. The data in the mock database gets reset every 24 hours and is common for all users so it may contain some unexpected values.

Mock API

You can import the below CURL commands to execute these APIs

Fetch Users

curl --location --request GET ''

Update Users

curl --location --request PUT '' \
--header 'Content-Type: application/json' \
--data-raw '{
"status" : "Approved"
