Snapchat Marketing API

  • Business account setup and API access approval requires organization verification and can take weeks
  • Creative asset uploads use a multi-step flow with separate endpoints for different media types and ad formats
  • Content must conform to Snap's specific format requirements -- vertical video, specific resolutions, and duration limits
  • The API is primarily advertising-focused, making organic content publishing through the API complex to navigate
  • OAuth implementation uses Snap's custom flow with short-lived tokens and complex scope requirements

RelayAPI

Ship Faster

Publish Snapchat content with a single API call. No creative asset management, no multi-step uploads, no format conversion. Send your media and metadata, we handle the Snap pipeline.

Official API, Zero Hassle

RelayAPI uses the official Snapchat Marketing API. Your content appears natively across Snap surfaces, while we handle business verification, token management, and format compliance.

Vertical-First Media Optimization

Snapchat requires vertical (9:16) content with specific resolution and duration limits. RelayAPI validates and optimizes your media for Snap's requirements, preventing upload rejections.

Frequently asked questions

Do I need a Snapchat Business account?

Yes. The Snapchat Marketing API requires a verified Business account with approved API access. Personal Snapchat accounts cannot publish through the API.

What content types can I publish to Snapchat through RelayAPI?

RelayAPI supports Snaps, Stories, Spotlight submissions, and ad creatives. All content must meet Snap's vertical format requirements, which RelayAPI validates automatically.

How does Snapchat content differ from other platforms?

Snapchat is vertical-first (9:16 aspect ratio) with strict duration limits. Stories are 1-60 seconds, and Spotlight accepts up to 60 seconds. RelayAPI validates these constraints and optimizes your media before upload.

Can I post to Snapchat Spotlight through RelayAPI?

Yes. RelayAPI supports Spotlight submissions with appropriate metadata, hashtags, and topic tags. We handle the Spotlight-specific submission flow and format requirements.
