Blink Reddit Ads

Blink Reddit Ads

Manage Reddit Ads through the Composio-backed composio_reddit_ads connector (83 native tools available). Reddit Ads is separate from regular Reddit (composio_reddit) — it lives on a different host, requires different OAuth scopes, and has its own connect step in Workspace Settings.

Provider key: composio_reddit_ads Base URL: https://ads-api.reddit.com/api/v3/ Auth: Composio-managed OAuth2

Setup the user must complete first

1. Connect "Reddit Ads" in Workspace Settings → Connectors. Connecting regular Reddit (for organic posts) is not the same — Reddit Ads needs its own connection.
2. The Composio Auth Config must request all of these scopes (Composio's names → Reddit's underlying scope names): identity, adsread (ads:read), adsedit (ads:edit), adsconversions, history, read. Without adsread the Reddit API returns 404 (yes — 404, not 403) on every /api/v3/* endpoint.
3. The user must be a member of a Reddit Ads Business Manager with at least one ad account assigned to them. Personal Reddit accounts that have never opened Reddit Ads return empty business / ad account lists.
4. After Composio Auth Config scope changes, the user must disconnect and reconnect the integration so Reddit re-issues the OAuth token with the new scopes baked in. Existing tokens are NOT silently upgraded.

Identity check

blink connector exec composio_reddit_ads me GET
# → returns the authenticated user's Reddit identity

Find your ad accounts

Most write paths need an ad_account_id (format: a2_<base36>). Walk the graph: user → businesses → ad accounts.

# Businesses you're a member of
blink connector exec composio_reddit_ads businesses GET

# Ad accounts under a business
blink connector exec composio_reddit_ads businesses/BUSINESS_ID/ad_accounts GET

Capture an id once and reuse it:

AD_ACCOUNT_ID=$(blink connector exec composio_reddit_ads businesses/BUSINESS_ID/ad_accounts GET --json \
  | python3 -c "import json,sys; print(json.load(sys.stdin)['data']['data'][0]['id'])")

Campaigns

# List campaigns in an ad account
blink connector exec composio_reddit_ads ad_accounts/$AD_ACCOUNT_ID/campaigns GET

# Create a paused campaign
# Objective options: TRAFFIC, CONVERSIONS, REACH, VIDEO_VIEWS, APP_INSTALLS, IMPRESSIONS, LEAD_GENERATION
blink connector exec composio_reddit_ads ad_accounts/$AD_ACCOUNT_ID/campaigns POST '{
  "data": {"name":"Spring launch","objective":"TRAFFIC","status":"PAUSED"}
}'

# Update campaign (e.g. activate)
blink connector exec composio_reddit_ads ad_accounts/$AD_ACCOUNT_ID/campaigns/CAMPAIGN_ID POST '{
  "data": {"status":"ACTIVE"}
}'

# Delete (soft-deletes; still appears in historical reports)
blink connector exec composio_reddit_ads ad_accounts/$AD_ACCOUNT_ID/campaigns/CAMPAIGN_ID DELETE

Ad groups

# List all ad groups in an account
blink connector exec composio_reddit_ads ad_accounts/$AD_ACCOUNT_ID/ad_groups GET

# Filter to one campaign
blink connector exec composio_reddit_ads ad_accounts/$AD_ACCOUNT_ID/ad_groups GET '{"campaign_ids":"CAMPAIGN_ID"}'

Reports (insights)

# Daily breakdown for one ad account, last 30 days
blink connector exec composio_reddit_ads ad_accounts/$AD_ACCOUNT_ID/reports POST '{
  "data": {
    "breakdowns":["DATE"],
    "fields":["IMPRESSIONS","CLICKS","SPEND","CONVERSIONS","CTR","CPM","CPC"],
    "starts_at":"2026-04-01T00:00:00Z",
    "ends_at":"2026-04-30T23:59:59Z"
  }
}'

# Per-campaign roll-up
blink connector exec composio_reddit_ads ad_accounts/$AD_ACCOUNT_ID/reports POST '{
  "data": {
    "breakdowns":["CAMPAIGN_ID"],
    "fields":["IMPRESSIONS","SPEND","CLICKS"],
    "starts_at":"2026-04-01T00:00:00Z",
    "ends_at":"2026-04-30T23:59:59Z"
  }
}'

SPEND is returned in micros of the ad account's currency.
