Verify Customjs access before automation work

Catch an expired API key before a document or screenshot run fails halfway through.

Trigger

Webhook received

Notis starts this workflow when an external tool or custom backend sends an HTTP request.

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

Credential failures create silent gaps in otherwise reliable automations.

  • Detects access problems early
  • Protects downstream runs from avoidable errors
  • Makes troubleshooting faster

Setup

Build it in a few focused steps.

  • 1Connect Google Tasks and Customjs in the Notis portal.
  • 2Create an automation for a preflight access check.
  • 3Tell Notis to verify the Customjs API key and report the result.
  • 4Pick the Notis webhook trigger and choose a report channel.
  • 5Send one test webhook and confirm the authentication result.

Questions about this workflow

When should I call this webhook?

Use it before a workflow that depends on Customjs access, such as PDF or browser actions.

Does it expose the API key?

No. The authentication action verifies the configured key and reports success or failure.
