Connect to Todoist

· 4 min read

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

Todoist uses Bearer (token) authentication. You must provide an API key or access token for Retool to authorize requests. Refer to the Todoist documentation on authenticating requests to learn how to obtain an API key or access token.

If Todoist is behind a firewall, you must also allow access from Retool's IP addresses. Add these IP addresses to your firewall's allowlist before you create the resource.

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. Select the REST API integration.

2. Configure the resource

Provide the necessary details to configure the resource so Retool can connect to Todoist. Not all settings are required but refer to the Todoist 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., Todoist).


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 Todoist.
