Snapchat API Error 429 — Too Many Requests (Rate Limit)

What Causes Snapchat Error 429?

Snapchat's Marketing API enforces rate limits to prevent abuse. Rate limit thresholds vary by endpoint type (read vs write) and app tier. Unlike Meta's detailed rate limit headers, Snapchat returns a simple 429 with a Retry-After header. High-frequency polling, bulk campaign creation without throttling, and unbounded retry loops are the most common causes.

• 1Polling campaign or ad performance data too frequently
• 2Bulk campaign creation without per-request delays
• 3Retry loops that fire immediately on error instead of backing off
• 4Multiple app instances making concurrent requests against the same token
• 5Fetching large dataset pages without cursor-based pagination throttling

How to Fix Snapchat Error 429

1. 1Check the Retry-After header in the 429 response — wait at least that many seconds.
2. 2Implement exponential backoff: 1s → 2s → 4s → 8s → 16s between retries, capped at 5 retries.
3. 3Reduce polling frequency: switch from per-minute polling to per-15-minutes or use webhooks for status changes.
4. 4Cache frequently-read data: campaign metadata, account structures, and creative lists do not change every second.
5. 5Use cursor-based pagination with brief pauses between page requests during large data exports.
6. 6For bulk launches, add a 100–200ms delay between each create request to stay within write-rate thresholds.
