Plans and usage
Free, Grow and Unlimited differ only in monthly invocation volume. What counts, what does not, and how to get alerted before you hit the cap.
Every plan includes all authentication methods, field mapping, CORS, duplicate protection, invocation history and replay. Plans differ only in how many invocations you can make.
| Plan | Invocations / 30 days |
|---|---|
| Free | 500 |
| Grow | 15,000 |
| Unlimited | No cap |
Usage is a rolling 30-day window, not a calendar month. Your dashboard shows current usage against the limit.
What counts
An invocation is one accepted request that we queue for Flow.
Not counted:
- Rejected requests (bad token, disabled webhook, unmapped field)
- Test invocations from the Test button
- Replays of past invocations
- Duplicates suppressed by Duplicate delivery protection
Hitting the limit
Once you reach it, further requests are rejected with quota_exceeded and a 400, and no
Flow workflow runs. Nothing is lost silently - the rejection is visible to your sender and
in the Live Request Inspector.
Change plan from Current plan -> Change plan on the dashboard.
Alerts before it happens
Open the bell icon on the dashboard's Invocations card:
| Alert | Default |
|---|---|
| 80% of plan used | On |
| Plan limit reached | On |
| Elevated failure rate | Off - switch it on |
Quota alerts are on out of the box. The failure-rate alert is not, and it is the one worth enabling: it emails you when an unusual share of your invocations start failing, which is how you find out a sender broke before your merchants do.
Alerts go to the store owner's email by default. Add more recipients in the same dialog - each one confirms by email and gets its own unsubscribe link.
