Connector capabilities

What can ToolJet do with OpenAPI?

Create queries for the operations your app needs, then connect their inputs and results to the interface.

Load an OpenAPI specification
Configure operation parameters
Run API operations

Operations and configuration can vary by connector version. Check the full OpenAPI guide.

An app you could build

Internal service console

Select an operation from your API specification, supply its parameters through a form, and present the response in a table or detail view.

Try this prompt

I have an OpenAPI specification for an internal service with an order lookup operation. Build a service console with a form for the operation's required parameters. Run the request on button click and show the response or a useful error message.

Start with this prompt in ToolJet. Sign in or create an account, then connect your data source and replace the example names and fields with yours.

Review the generated app, configure permissions, and test its queries before sharing it with your team.

Connect OpenAPI

Start with the connection.

Before you begin

Access to the OpenAPI account or endpoint you intend to connect, with the credentials and permissions specified in its setup guide.

Add the data source
Open Data Sources in your ToolJet workspace. Select OpenAPI and enter the required connection details.
Configure and test a query
Choose an operation and supply its inputs. Start with a read operation where available; test writes with non-production data.
Build the interface
Bind query results to components and connect actions to app events. Verify permissions and error handling before rollout.
