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 Basic free 123 Form Builder plan, you can use up to 100 API calls per day.
If you are a Wix Premium or Weebly Silver user, you have available 200 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 API calls per day, upgrade your account to Gold, Platinum, or Professional.
The number of API calls/day can be checked in the My Account → API Keys section.
