Connect to AssemblyAI

· 3 min read

You can connect to AssemblyAI using Retool's REST API integration and make it available as a resource. Once complete, you can write queries to interact with the AssemblyAI API.


All users for Retool organizations on Free or Team plans have global Edit permissions and can add, edit, and remove resources. If your organization manages user permissions for resources, you must be a member of a group with Edit all permissions.

To create your AssemblyAI resource, you'll need:

1. Create a new resource

Sign in to your Retool organization and navigate to the Resources tab. Click Create new, then select Resource.

Retool can connect to almost any API or database, and has built-in integrations for popular data sources. For AssemblyAI, you'll use the REST API integration.

2. Configure the resource

Provide the necessary details to configure the resource so Retool can connect to AssemblyAI. Not all settings are required but refer to the AssemblyAI documentation to learn what is needed.


These settings configure the name and location of the resource within Retool.


The name to use for the resource (e.g., AssemblyAI).


The folder in which to save the resource.


A brief description of the resource (e.g., Customer data).


These settings configure how Retool connects to AssemblyAI.

3. Save the resource

Click Create resource to complete the setup. You can then click either Create an app to immediately start building a Retool app or Back to resources to return to the list of resources.

Wrap up

Your AssemblyAI resource is now ready to use. You write queries to make API requests by specifying the request method and endpoint, additional parameters to include, and the request body.

To verify you can successfully interact with AssemblyAI, write a test query to retrieve some data. The following example request fetches a transcript with a given identifier as a URL path parameter.
