You can have predefined API templates for each form, which can be reused for sending API requests.
These templates allow you to define the structure of the API request, including the URL, body of the request and additional information.
To manage API templates, you can navigate to Configure -> Message templates -> API templates. This section allows you to add, edit, or delete the API templates, along with the option to mark them as active or inactive.
Each API request would contain all of the submission's responses and metadata.
Additional data
If you want to append additional data to the body, then you can add in those key-value pairs under the additional data section.
