An authentication guide for connecting a Notion Worker to outside services such as GitHub, Stripe, Salesforce, Google, or Slack. It covers personal API keys, personal access tokens, and OAuth, a sign-in method where the service grants access without sharing a password.

Use it when a worker needs to read from or send data to an outside service. It helps decide between a personal key or token and OAuth by checking the provider’s current documentation.

It helps choose the right way to give the worker access to a non-Notion service. It also separates these credentials from Notion API tokens and ntn login.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00054	$0.02773
Opus 5	$0.00027	$0.01386
Sonnet 5	$0.00011	$0.00555
Haiku 4.5	$0.00005	$0.00277

Security

Grade A, and why

auth-guide scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

How it starts

The opening of the file, as written. The whole thing — 228 lines — stays where its author put it; the contents beside it link to each section on GitHub.

What this guide is for

This guide is for authentication against the third-party service your worker integrates with — the place data is coming from or going to (GitHub, Stripe, Salesforce, Google, Slack, etc.).

Use it when the worker needs credentials for a non-Notion API. Do not use it for Notion API tokens, ntn login, or general Notion workspace setup.

Most workers will use one of two auth patterns from the upstream service:

personal API key / personal access token
OAuth

Decision framework

Before recommending anything, check the provider's current developer docs. Confirm whether it offers:

personal API keys / personal access tokens
OAuth
neither

Always research the provider's current auth docs on the web before advising the user. Do not rely on memory for auth availability, setup steps, or settings locations.

Then choose mechanically:

Service offers personal API keys / PATs? Recommend API key / PAT first. It is usually the simplest fit for an individual-scoped worker.
Service is OAuth-only? Use OAuth.
Both exist, but the worker should not depend on one person's credential or should be easy to re-auth if that person leaves? Recommend OAuth.
Service has neither? See "When neither option is available" at the end of this guide.

State the recommendation in one sentence with the reason. Example: "Linear offers personal API keys, so use an API key; it's the simplest fit here."

Setup: API key

Pattern: store the credential in .env (or directly in the deployed worker's secrets), read it from process.env inside the capability's execute, push .env to the deployed worker before going live.

Look up the provider's current docs for creating a token. Link the user to the exact settings page when possible.
Have the user add the token to .env themselves (create the file if it doesn't exist), or tell them the equivalent ntn workers env set command. Tell them the variable name to use:
```
GITHUB_API_TOKEN=<paste your token here>
```

auth-guide is a skill published in the GitHub repository colebemis/notion-workers (127 stars, last pushed 2d ago), licensed MIT. It adds 54 tokens to every session and 2,773 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
