API calls are operations performed when another service communicates with ours. For example, if you use Zapier, each time the two apps in a zap are synced, a certain number of API calls is needed. The syncing interval is either 5 or 15 minutes.
On the free 123 Form Builder plan, you can use up to 20 API calls per day.
If you are a Wix Premium user or Weebly Silver you also have available 20 API calls/day.
On our native paid plans, the number of API calls that you can use is unlimited. If you want to use more than 20 API calls per day, upgrade your account to Individual or Team.
The number of API calls/day can be checked in the My Account – API Keys section.
