Rate Limiting
Junction does not impose a per-customer rate limit on server-to-server API calls at this time.
However, you may occasionally encounter 429 Too Many Requests or 503 Service Unavailable from our infrastructure. You should be prepared to retry your API requests with a reasonable exponential backoff strategy.
Targeted rate limits
You may encounter 429 Too Many Requests in the these specific scenarios:
| Endpoint | Authentication Scheme | Rate Limit |
|---|---|---|
POST /user/refresh/{user_id} | Vital API Key | 8 per hour per user |
Junction may adjust rate limiting based on real-world usage patterns. We will give you sufficient notices if a new enforcement would impact your existing usage patterns.
