Publer Rate Limits

Publer publishes concrete, numeric rate limits. The API limit is 100 requests per 2-minute fixed window, applied PER USER ACCOUNT across all of that user's API keys — creating additional keys does not buy additional throughput. Every response carries X-RateLimit-Limit, X-RateLimit-Remaining and X-RateLimit-Reset, and exhaustion returns 429 with a distinct error envelope. Separately, Publer enforces per-network DAILY POST LIMITS on a rolling 24-hour UTC window that vary by plan; these are business limits enforced downstream and surface as per-account job failures, not as HTTP 429.

Publer Rate Limits is the machine-readable rate-limit profile for Publer on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 18 rate-limit definitions, measuring requests, posts, and jobs.

The profile also includes 4 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include Social Media, Scheduling, Publishing, Content Management, and Marketing.

Policies

Requesting higher limits
Email support@publer.com with expected request volume (per minute/hour/day), use case and critical endpoints, and project/company contact info.
Publisher best practices
Publer recommends caching idempotent responses, using bulk endpoints (POST /posts/schedule for multiple posts), staggering non-urgent requests to off-peak hours, monitoring the X-RateLimit-* headers, and exponential backoff as the limit approaches.
Async processing
Scheduling and publishing are accepted (202) and processed asynchronously; poll GET /job_status/{job_id} for completion and inspect payload.failures[].
Downstream network limits
Each connected social network enforces its own publishing limits that apply on top of Publer's, and Publer's own daily post limits are aligned to those community guidelines.
