How it works

Reddit requires an OAuth2 bearer token even for script-type apps that use password auth. Anodizer performs a two-step flow on every run:

Exchanges application_id + REDDIT_SECRET + username + REDDIT_PASSWORD for a short-lived bearer token via POST /api/v1/access_token.
Submits a link post to the target subreddit via POST https://oauth.reddit.com/api/submit.

Reddit's API returns HTTP 200 even when a submission fails at the application level. Anodizer checks the json.errors array in the response body and treats any non-empty errors array as a failure.

Setting up a Reddit app

Go to https://www.reddit.com/prefs/apps and create a new script app.
Copy the client ID (shown under the app name) into application_id.
Copy the secret into REDDIT_SECRET.
Use the Reddit account that owns the app as username and set REDDIT_PASSWORD.

Script-type apps are limited to posting as the app owner. If you need to post as a different account, create a separate Reddit account and app for that account.

Example with secrets from environment

announce:
  reddit:
    enabled: true
    application_id: "{{ Env.REDDIT_APP_ID }}"
    username: "{{ Env.REDDIT_USERNAME }}"
    sub: "myproject"
    title_template: "{{ .ProjectName }} {{ .Tag }} released"
    url_template: "{{ .ReleaseURL }}"

REDDIT_APP_ID=abc123xyz
REDDIT_USERNAME=release_bot
REDDIT_SECRET=super_secret_value
REDDIT_PASSWORD=bot_account_password
