Form.io validation endpoint

Form.io not only serves as a Form platform for your Serverless applications but can also serve as a complete REST API platform as well. This is because everything that happens within Form.io, does so through the use of a robust REST API call within the form platform.

The following documentation outlines a complete walkthrough of using the Form.io API platform for validating a form.

To use Form.io first we have to create an account next create a project, setup it, and create a form.

How to use the Form.io API .

1. We have to login

   endpoint: https://formio.form.io/user/login
   header: content-type : application/json
   body  : 
   {
       "data": {
           "email": "{{email}}",
           "password": "{{password}}"
       }
   }

From the response’s header get the x-jwt-token and save it in a variable if you are using POSTMAN and from the body of response you will find login info about the user and list project .

2) To validate a form we need 2 things the PROJECT_ID and the FORM_NAME now we can format the ENDPOINT like that

https://{{PROJECT_ID}}.form.io/{{FORM_NAME}}/validate
header: content-type : application/json, x-jwt-token : {{x-jwt-token}}
data : {
	"data": {
	 // form data
	}
}

To validate a form there is 3 sections that interest us :

1. Validation

2. Conditional

3. Logic

For the validation section all constraint work except JSONLogic Validation

For Conditional section nothing works, the API does not react on any code .

And for the logic section only simple logic works
