## What it does

Reach for this skill before the agent touches the Document Authoring API: pushing an HTML page, listing documents in a repo, kicking off a preview. It first looks for a cached token in `~/.aem/da-token.json`. If that token is still valid, no browser opens. Tokens last about an hour with a 60-second buffer, so a single session rarely needs a second login.

With no cache, the skill runs the OAuth 2.0 implicit flow through `da-auth-helper`: `npx github:adobe-rnd/da-auth-helper token` opens a browser window, you sign in to Adobe IMS, and the token lands on stdout. Then it verifies the result — a request to `admin.da.live/list/{{ORG}}/{{REPO}}` has to come back HTTP 200 before `DA_TOKEN` counts as ready.

You need Node.js 18+, a browser on the same machine, and network access to `ims-na1.adobelogin.com`. On a headless box the window never appears, so pick a fallback up front: the auth tool of a DA MCP server, or pasting a token copied from DevTools. A 403 on the check is not a token problem — it means the signed-in user lacks access to that `{{ORG}}/{{REPO}}`.

Inside the `create-site` flow, skip this skill; authentication is already part of it.

```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/adobe/skills/tree/HEAD/plugins/aem/edge-delivery-services/skills/da-auth/SKILL.md

## When to use it
- get an Adobe IMS token for `admin.da.live` calls
- push HTML content to DA without copying a token by hand
- list documents in a DA repository
- trigger a DA content preview
- reuse a cached token instead of logging in again

## Example prompts
- Get a DA token and push this page to the repo
- I need `DA_TOKEN` to list the documents in DA
- Refresh the token and trigger a preview of this page

# DA Authentication

Gets a valid Adobe IMS access token and stores it in `DA_TOKEN` for use in subsequent `admin.da.live` API calls.

## When to Use This Skill

Use this skill whenever you need to call the DA Admin API (`admin.da.live`) and do not already have a valid token in scope. Common cases:
- Pushing or updating page content in DA
- Listing documents in a DA repository
- Triggering a DA content preview

Do NOT use this skill when:
- You already obtained a `DA_TOKEN` earlier in the same session and it has not expired (tokens are valid for ~1 hour with a 60-second buffer)
- The **create-site** skill is already handling authentication as part of its own flow
- A DA MCP server is active in the session — use its authentication tool directly instead

## Prerequisites

- Node.js 18+ installed
- A browser accessible from the machine (for the OAuth flow)
- Network access to `ims-na1.adobelogin.com`

## Related Skills

- **create-site** — includes its own DA auth step for new site onboarding; do not invoke da-auth separately within that flow
- **content-driven-development** — use da-auth before pushing authored content to DA
- **building-blocks** — use da-auth if test content needs to be pushed to DA for block development
- **snowflake** — invoke da-auth before Phase 5 (round-trip) so `$DA_TOKEN` is set when snowflake PUTs the converted page to DA
- **da-content** — the reference for what to do with `$DA_TOKEN` once you have it (Source API, preview/publish)

## Step 1: Check for a Cached Token

Before triggering a browser login, check whether a valid token is already cached.

```bash
DA_TOKEN=$(node -e "
  const fs = require('fs');
  const p = process.env.HOME + '/.aem/da-token.json';
  try {
    const t = JSON.parse(fs.readFileSync(p, 'utf8'));
    if (t.expires_at > Date.now() + 60000) process.stdout.write(t.access_token);
  } catch {}
")
```

If `DA_TOKEN` is non-empty, skip to **Step 3**.

## Step 2: Obtain a Token *(login required)*

Choose the option that fits the environment:

**Option A (preferred) — `da-auth-helper` CLI:**

The `da-auth-helper` tool handles the full IMS OAuth 2.0 implicit flow, caches the token at `~/.aem/da-token.json`, and prints the token to stdout.

```bash
# Run directly without a global install
DA_TOKEN=$(npx github:adobe-rnd/da-auth-helper token)
```
