Rate limits
Each plan has a monthly submission cap. When you hit it, new submissions return a 429 error until the next billing period — or you upgrade. See the pricing page for the current numbers.
Behavior at the limit
A request that exceeds the monthly cap returns:
HTTP/1.1 429 Too Many Requests with the JSON body described in Response format.
What counts
Successful form submissions across all of your forms count toward the same pool. The dashboard shows current usage with days left in the billing period.
Webhook endpoint cap
Personal and legacy Free plans get 1 webhook endpoint per form, enough to wire one destination end-to-end. Lite and Pro unlock unlimited endpoints per form, so a single submission can fan out to Slack and Zapier and your own backend. There is no per-month delivery cap on any plan; webhooks fire on every non-spam submission that lands. See Delivery & retries for the full behavior.
