# How to Automate Reddit Ad Campaigns using the API

- Tool: API Automations
- Difficulty: Advanced
- Fix time: 1-2 hours
- Compatibility: Reddit Ads account required | Contact Reddit sales for API access | Separate from Data API
- Last updated: May 2026

## TL;DR

Reddit Ads API (ads-api.reddit.com/api/v2.0/) is entirely separate from the Data API and requires Reddit Ads account access. Use it to automate campaign reporting, budget adjustments, and performance monitoring. Access requires contacting Reddit sales — it's not self-serve. Rate limits are undocumented. Most founders searching this need report automation and budget rules, not full campaign creation.

## Best practices

- Pull reports at the campaign level first, then drill to ad group level only for campaigns that need attention
- Test budget rules against 30 days of historical data before running them live to calibrate thresholds
- Implement safeguards: maximum budget increase per run (e.g., no more than 50% in a single automated change)
- Use separate OAuth2 applications for development and production ad accounts
- Cache campaign metadata (names, current budgets) for 1 hour to reduce API calls
- Always include the previous value in budget change logs: 'Changed daily budget from $200 to $240'
- Set up Reddit Ads account-level spend alerts as an independent safety net against automation failures
- Contact Reddit's API team for documented rate limits before scaling your automation to high request volumes

## Frequently asked questions

### Is the Reddit Ads API the same as the Reddit Data API?

No — they are completely separate products with different base URLs, authentication requirements, and pricing. The Data API (oauth.reddit.com) is for reading and posting content. The Ads API (ads-api.reddit.com/api/v2.0/) is for managing advertising campaigns. You need an active Reddit Ads account and separate API approval for the Ads API.

### How do I get access to the Reddit Ads API?

The Reddit Ads API is not self-serve. You need to contact Reddit Ads support through your ads.reddit.com account dashboard, or reach out to your Reddit account manager if you have one. Smaller advertisers may have limited access — the API is primarily available to larger spenders and agencies.

### What happens when I hit the Ads API rate limit?

The Ads API returns HTTP 429 Too Many Requests. Unlike the Data API, the Ads API rate limits are not publicly documented. Design defensively: add 0.5-1 second delays between calls, use batch report endpoints, and implement exponential backoff starting at 5 seconds. Contact Reddit sales for specific rate limit numbers for your account tier.

### Can I create entirely new campaigns via the API, or just manage existing ones?

The Ads API supports full campaign creation via POST /api/v2.0/campaigns, ad group creation, and ad creation. However, most automation use cases focus on reporting and budget adjustments rather than programmatic campaign creation. Campaign creation via API requires careful setup of targeting parameters, creatives, and compliance settings.

### Is the $12,000/month Data API tier required for Ads API access?

No. The commercial Data API tier ($12,000/month for 50M calls) is for high-volume content reading and posting automation. The Ads API is a separate product available to Reddit Ads customers — you pay only for your ad spend, not a separate API access fee.

### Can I automate cross-platform ad reporting (Reddit + Meta + Google) in one script?

Yes — the pattern is the same for each platform's ads API. Pull data from each API separately, normalize the metrics (impressions, clicks, spend, CPC) into a common schema, aggregate in your reporting layer, and deliver in one unified report. Consider using a data pipeline tool like n8n or Airbyte to standardize multi-platform ad reporting.
