Creating Custom Triggers

Custom form triggers let you perform custom business logic on a successful form submission, e.g. sending form submission data to an e-mail address of your choice, or maybe sending the data via an HTTP request, issued to your custom API endpoint.


To learn more about built-in triggers and triggers in general, visit the Triggers article.

Creating a custom trigger can be achieved by registering a simple form-trigger-handler plugin in the Form Builder API. In other words, in the api/formBuilder/src/index.ts file.

Consider the following example:

type: "form-trigger-handler",
trigger: "e-mail",
async handle({ trigger, data, formSubmission }) {
const myEmailClient = ...;

As we can see, the two properties that need to be defined are trigger and handle, which, respectively, define the name of the trigger, and the logic that needs to be executed. In this particular example, we are executing the send method on an imaginary e-mail client - myEmailClient.

Note that the handle callback function can be an async function. Also, there is no limit when it comes to the number of triggers that can be defined.
