What is the API key and when do I need it?

Important Note

This version of the API was deprecated. If you still need to automate your data collection processes, and retrieve collected data or make various operations related to your 123FormBuilder account through API calls, you can use our new and improved API v2. Please visit our developer documentation for more details.

The API key is a secret token that is used to identify the origin of a request. Each 123FormBuilder account has an API key. You can find it by selecting your username and then clicking on API Keys.

API Keys

In case it’s not already displayed, you’ll need to generate it by pressing the Create now button. After you create it, you can copy it and also see how many API calls per day you can make.

Copy Key

You need this API Key in three main situations:

1. When you want to publish your forms on certain platforms, such as Joomla, or Sitefinity.

2. When you want to integrate your forms with certain 3rd party apps (e.g. Zapier).

In your form’s Applications section, you can find the most used zaps between us and other applications.

Applications by Zapier

Click on 123FormBuilder to open all the available zaps that you can create with us.

More integrations

3. When you want to use our API in your own development endeavors. We invite you to browse our knowledge base for developers for more information.

For points 2 and 3, the number of API calls that you can use in a day is very important.


  1. Hi, we
    just built a web site on the Wix platform to connect to our warehouse management system and I have added and customized a 123 form to our site! Now my question; In order to process the new customer registration/ order on our web site and connect the customer account to our warehouse portal, we must connect to (Wix-API) or (123FormBuilder-API) ???

    1. Hello Mow. You will need to add a script on the form which will send the submissions data to your own warehouse management system. To add a script to your form you will need our Platinum Plan. The script will be placed in your form’s Settings – Advanced section – Form Tab – Add a JS script to your form.
      For API integrations you will need to use 123FormBuilder API since we are a thrid-party app on Wix website.

  2. Is there anyway to make it so that the fields that are clicked on my employee forms update my quick books client accounts so I don’t have to enter it manually? Could it automatically enter charges from my reoccurring charges list on QuickBooks?

    1. Hello!

      To get your API code, go to My Account and you’ll find the code under Account Details. If no code is displayed, click on the create now link to generate your code.

  3. Dears,

    I would like to use your form to submit the information to an external API.

    How can I do so?
