123Formbuilder Rate Limits

Rate limit definitions for the 123FormBuilder REST API v2. Reconciles the published per-plan daily API call quotas with the implicit per-form webhook ceiling. The provider does not publicly document burst, per-second, or per-minute throttles; values marked "unspecified" must be confirmed with support before being relied on contractually.

123Formbuilder Rate Limits is the machine-readable rate-limit profile for 123FormBuilder on the APIs.io network, in the API Commons Rate Limits shape.

It captures 7 rate-limit definitions, across the free, gold, platinum, diamond, and enterprise tiers, measuring requests_per_day, webhooks, and scheme.

Limit state is signalled in the limit, remaining, reset, and retryAfter response headers, and an exhausted limit returns HTTP 429.

This profile was written by API Evangelist and has not been verified against a page the provider published; treat every limit as unconfirmed until a dated transcription replaces it.

The profile also includes response codes documented for throttled, quotaExceeded, and serviceUnavailable.

Tagged areas include Online Forms, Form Builder, Submissions, Rate Limiting, and Quotas.
