Snap Marketing API
Programmatic access to Snapchat's advertising platform for creating and managing ad accounts, campaigns, ad squads, ads, creatives, and audiences across Snap's Story, Spotlight, and Discover placements.

⚙ Agent Friendliness
🔒 Security
All traffic over TLS. OAuth 2.0 with short-lived access tokens (30-minute expiry) is a security positive. Client secret must be kept server-side. Scopes are coarse — snapchat-marketing-api grants broad access to all ad account operations. No webhook signature verification is offered since webhooks are not supported.
⚡ Reliability
Best When
You are running paid campaigns targeting Gen Z and millennial audiences and need to automate creative management, audience syncing, or budget optimization across Snap's ad formats.
Avoid When
Your target audience skews 35+ or B2B, or you cannot complete Snap's app review process since the Marketing API requires explicit permission approval before production access.
Use Cases
- • Automate bulk creation of Snap ad campaigns with localized creatives for multi-market rollouts
- • Sync audience segments from a CDP to Snap Audience Match for targeting custom and lookalike audiences
- • Pull campaign delivery stats and swipe-up metrics for integration into a cross-channel performance dashboard
- • Pause underperforming ad squads automatically when CPA exceeds a defined threshold
- • Upload and manage creative assets (video, images) programmatically for A/B testing at scale
Not For
- • Reaching audiences outside the 13–34 demographic — Snapchat's user base skews young and reach is limited for older demographics
- • Organic Snapchat content management or Stories publishing — the Marketing API covers paid ads only
- • Real-time impression-level bidding control — Snap's auction is automated and not externally accessible
Interface
Authentication
OAuth 2.0 authorization code flow. Access tokens expire in 30 minutes and must be refreshed using a refresh token (expires in 90 days). App must be approved for Marketing API access via Snap's developer portal — this requires an application submission and review period. Scopes include snapchat-marketing-api for full access. Client credentials flow is not supported; user-delegated OAuth is required.
Pricing
API access is free with approved app status. Ad spend is billed to the Snap Ads Manager account. Minimum daily budget requirements apply at the ad squad level ($20/day minimum for most formats).
Agent Metadata
Known Gotchas
- ⚠ App review for Marketing API access can take 1–2 weeks and requires a detailed use case description — agents cannot access production ad accounts without explicit approval, even with a valid OAuth token
- ⚠ The ad object hierarchy (Organization → Ad Account → Campaign → Ad Squad → Ad) requires correctly scoping API calls to the right ad account ID, which is separate from the Organization ID returned during OAuth
- ⚠ Refresh tokens expire after 90 days of inactivity — agents running infrequently must implement token refresh tracking to avoid losing access and requiring full re-authorization
- ⚠ Creative assets (video, images) must be uploaded via a separate Media Library endpoint before they can be referenced in ads; there is no inline asset creation, requiring a multi-step workflow
- ⚠ Reporting data has a processing delay of up to 3 hours — agents querying same-day stats may get incomplete data, and there is no metadata field indicating data freshness in the response
