API Limit - how could I have reached this limit?

I have received the message below via email. I don't understand now I could possibly have reached 1000 requests because I have only been working on the form for the last hour and it has only just gone live? It is a gift registry which needs to be live. The website has only just been published with this form on it? Please can you look into this - I appreciate it thank you.

It seems like you have reached your API limit. FREE accounts are limited to 1,000 requests per day. Your API access has been disabled for the rest of the day.Since we understand that it can be an inconvenience to have your access stop working because you have reached your API limit, we'd like to remind you that you can upgrade and your API access will be running smoothly again.

The API limits reset on daily basis. If you reached the limit before the day ends, you have 2 options:

First, you can upgrade your account to a larger plan. 

Second, just ask the support team to reset it, however, the turnaround time can be 1-2 hours. You may ask us in advance before the limit it reached.

Here are the API limits according to plan subscriptions.

Free: 1000

BRONZE:10,000

SILVER: 40,000

GOLD: 100,000

API limit counts the number of times APPS on your forms are called. Please note that the API limit is different from your submission limit. I have reset the API limit for your account and you may disregard the email you have received.

Let us know if you need any further assistance. Thank you.
