Validate CustomJS access before execution

Know your automation connection works before relying on it.

Trigger

New Task Created

Trigger when a new task is added to Todoist.

Action

Authenticate CustomJS API Key

Tool to authenticate a CustomJS API key. Use when verifying a user's API key before making further requests.

Why this helps

A task can wait silently when an expired API key blocks the automation.

  • Detect credential issues early
  • Reduce failed runs
  • Make setup problems visible

Setup

Build it in a few focused steps.

  • 1Connect Todoist and CustomJS once in the Notis portal.
  • 2Create an automation for CustomJS access checks.
  • 3Tell Notis to authenticate the CustomJS API key when a new task mentions a CustomJS operation, then report success or the exact failure.
  • 4Pick Todoist New Task Created as the trigger and choose the run report channel.
  • 5Test with one task that requests a CustomJS action.

Questions about this workflow

Does this perform the requested action?

No. It verifies access so a later workflow can run safely.

What should I do after a failed check?

Update the CustomJS API key in the connected account and rerun the test task.
