Reddit Commenting V1

Three self-contained commenting actions — write a top-level comment on a post, reply to an existing comment, or edit your own comment's body. One run = one action = one dataset record.

Bring a Reddit Token V2 + matching proxy, or reuse a saved account from the Reddit Vault. Pick the action, paste the target, write the body, hit Start.

---

What you can do

The Post field accepts: full URL (https://reddit.com/r/sub/comments/1sys4r2/...), stripped ID (1sys4r2), or t3_ fullname (t3_1sys4r2). The Parent comment / Comment fields accept: full URL, stripped ID (ogv9p8c), or t1_ fullname (t1_ogv9p8c).

Reddit markdown is supported in every text field — **bold**, *italic*, > quote, [link](url), - bullet, fenced code, tables.

All actions (Reddit account required)

1. Create Comment — write a top-level comment on a post

Credentials

All 3 actions need a signed-in Reddit account. Save it once in Reddit Vault and reuse the name forever, or paste a Token V2 + matching proxy inline for one-off runs.

Credential lifetimes

Credential	Lifetime	When to refresh
Token V2 (token_v2 cookie)	~24 hours	Daily — or save a Reddit Session in the vault and let it auto-refresh
Reddit Session (reddit_session cookie)	~180 days	Roughly twice a year, or when a run reports unauthorized

How to extract these from your browser: open Reddit in Chrome / Brave / Edge / Firefox, then DevTools → Application → Cookies → https://www.reddit.com. Filter by token_v2 or reddit_session and copy the Value column.

Option A — Use saved account (vault) (recommended)

1. Run the Reddit Vault actor once with mode STORE, an account name (e.g. motor_tip8865), your Token V2 (or Reddit Session for auto-refresh), and the matching proxy.
2. In this actor, set Credential source = Use saved account (vault) and Saved account name = motor_tip8865.
3. Token V2 + proxy are pulled from the vault on every run. If you saved a Reddit Session, the Token V2 auto-refreshes whenever it expires.

Option B — Paste Token V2 + proxy inline

1. Set Credential source = Paste Token V2 + proxy.
2. Paste the eyJ… Token V2 cookie value (encrypted by Apify at rest).
3. Paste the Proxy as ip:port:user:pass — must be the same IP that minted the Token V2 (Reddit IP-binds these cookies).

---

How to run

1. Action → Create Comment, Reply to Comment, or Edit Comment.
2. Fill the matching section (only the chosen action's section matters — the others are ignored).
3. Pick a Credential source and fill the matching vault or manual fields.
4. Hit Start. One run = one comment action = one row in the dataset.

---

Output

Every run pushes exactly one record to the run's default dataset. Success and failure both produce a row — the success field distinguishes them.

Front-loaded column	Meaning
success	true if Reddit accepted the action, false otherwise
operation	create, reply, or edit
comment	The comment target you supplied (reply / edit actions)
post	The post target you supplied (create action)
text	First 200 characters of the body you sent (echoed for traceability)
account_name	Vault account name (or "manual" for inline credentials)
error	Human-readable message on failure, null on success
error_kind	Short error code (UNAUTHORIZED, RATELIMIT, THREAD_LOCKED, BANNED, SHADOWBAN, NOT_OWNER, …), null on success
bearer_expires_at	When the saved Token V2 expires (helps you spot upcoming refresh)
rate_limit / rate_used / rate_remaining / rate_reset_in_seconds	Live per-account rate-limit counters from Reddit

Need the new comment's ID / permalink in the output? Use Reddit Commenting V2 — same actions, richer success record (comment_id, permalink, parent fullname), plus optional inline images and GIFs.

Common edge cases

Edge case	Cause	How it surfaces
Bearer expired	Saved Token V2 past ~24 h, no vault session for auto-refresh	Row with success: false, error_kind: UNAUTHORIZED. Re-save the account in Reddit Vault with a Reddit Session for auto-refresh.
Bearer minted on a different IP	Token V2 minted on a different proxy than the one paired with it	Row with success: false, error_kind: UNAUTHORIZED. Re-mint the Token V2 on the proxy you'll use, save them as a pair.
Thread locked	Mod has locked the post / comment — no new replies accepted	Row with success: false, error_kind: THREAD_LOCKED. Pick a different target.
Thread archived	Posts older than 6 months — Reddit no longer accepts comments	Row with success: false, error_kind: THREAD_ARCHIVED. Pick a non-archived target.
Banned from subreddit	Your account is banned from the subreddit	Row with success: false, error_kind: BANNED. Use a different account or get unbanned.
Subreddit private / quarantined	Your account doesn't have access (or hasn't accepted the quarantine prompt)	Row with success: false, error_kind: FORBIDDEN or QUARANTINED.
Reddit rate-limit hit	Per-account write throttle reached	Row with success: false, error_kind: RATELIMIT. Wait — rate_remaining tells you how many calls are left.
Comment shadowbanned	Reddit accepts the comment silently but doesn't show it to other users (anti-spam shadowing on new / low-karma accounts)	Row with success: true — comment is in the dataset but may not appear publicly. Warm the account up before automating.
Not your comment (edit)	The comment belongs to a different account	Row with success: false, error_kind: NOT_OWNER.
Empty body	Forgot to paste comment / reply text	Run FAILED immediately, no row pushed, no charge.
Missing required input	Forgot to paste the post / comment URL	Run FAILED immediately, no row pushed, no charge.

Why this actor is fast

• Speed — 1–3 seconds per action, end-to-end. Pure HTTP to Reddit. No browser to boot, no Playwright / Selenium / Puppeteer overhead. Competing browser-based actors typically take 15–60 seconds per call.
• Reliability — zero browser flakiness. No headless-Chromium crashes. No JS-render timeouts. No captcha pages.
• Footprint — under 100 MB RAM per run. Most browser-based actors need 1–4 GB. Built for reliability behind the scenes — just paste your inputs and run.

Status & error reference

Run status (Apify-side, shown on the run page)

Status	Apify message	Meaning	What to do
	"Actor succeeded with N results in the dataset"	Run finished, one record pushed.	Open the dataset to view the result.
	"The Actor process failed…"	Validation error or missing required input.	Check the run log. You are NOT charged for failed runs.
	"The Actor timed out. You can resurrect it with a longer timeout to continue where you left off."	Run exceeded timeout (rare — comments are fast).	Re-run; check proxy is reachable.
	"The Actor process was aborted. You can resurrect it to continue where you left off."	You stopped the run manually.	No charge for unpushed results.

Common in-run conditions (visible in run log and output record)

Condition	Cause	Result
RATELIMIT from Reddit	Per-account write throttle hit.	Run SUCCEEDED, failure row with error_kind: RATELIMIT.
Bearer expired / invalid	Saved Token V2 past ~24 h, no vault session for auto-refresh.	Run SUCCEEDED, failure row with error_kind: UNAUTHORIZED.
Thread locked / archived	Post / comment no longer accepting new replies.	Run SUCCEEDED, failure row with error_kind: THREAD_LOCKED or THREAD_ARCHIVED.
Subreddit ban / quarantine	Account doesn't have write access to the community.	Run SUCCEEDED, failure row with error_kind: BANNED or QUARANTINED.
NOT_OWNER (edit)	The comment isn't yours.	Run SUCCEEDED, failure row with error_kind: NOT_OWNER.
Validation error: missing target / body	Required input not provided.	Run FAILED immediately, no charge.

---

Pricing

Pay-per-result. You're only charged for records actually pushed to the dataset — failed runs, validation errors, and credential errors that never reach Reddit cost nothing.

Event	Trigger	Price (per 1,000)
result	Each row pushed to the dataset (success or failure)	$1.99

Every comment — create, reply, or edit — is one row, one charge.

Need a different shape of data?

• Reddit Vault — save Reddit accounts once, call them by name from this actor (free)
• Reddit Commenting V2 — newer version: returns comment_id + permalink on success, supports inline images / GIFs
• Reddit Manage Comments V2 — Comment Insights, Linked Comment Info, save / unsave / follow / unfollow / delete / edit
• Reddit Voting V2 — upvote / downvote / clear your vote on posts and comments
• Reddit Posting V2 — create text / link / image / gallery / video / GIF / crosspost / poll posts
• Reddit Post Manager V1 — edit / delete / save / flair / lock / NSFW / spoiler / hide / report your posts
• Reddit Posts & Feeds V2 — home feed + post state controls
• Reddit Subreddits — info, browse, join / leave, create
• Reddit Users V1 — profile, lookup, follow, block, friend

All of them accept the same accountName field, so saving credentials in Reddit Vault unlocks them all.
