Plans and limits
Which plans include webhooks, flow triggers and API connections, and the bounds each of them enforces.
Webhooks, flow triggers, API connections and AI actions are part of the Business plan. Every number on this page is generated from the code that enforces it.
By plan
| Free | Starter | Pro | Business | |
|---|---|---|---|---|
| Webhooks, flow triggers and API connections | No | No | No | Yes |
| Automations | No | No | Yes | Yes |
| Automation flows | 0 | 0 | 5 | 25 |
| Templates automations may send per day | 0 | 0 | 0 | 1,000 |
The daily template allowance is shared by an account and its projects. Automations on a plan without webhooks still run on customer messages, keywords and buttons; they cannot be started by your system or call it.
When an account leaves the Business plan, its webhook endpoints, connections and actions
are kept and can still be edited, switched off or deleted, but nothing is sent to or
called through them, and flow trigger URLs answer 403 not_in_plan.
