JS API Client

This library offers the API client to communicate with mosparo to verify a submission.


With this JavaScript library you can connect to a mosparo installation and verify the submitted data.


Install this library by using npm:

npm install @mosparo/api-client


  1. Create a project in your mosparo installation
  2. Include the mosparo script in your form
<div id="mosparo-box"></div>

<script src="https://[URL]/build/mosparo-frontend.js" defer></script>
    var m;
    window.onload = function(){
        m = new mosparo('mosparo-box', 'https://[URL]', '[UUID]', '[PUBLIC_KEY]', {loadCssResource: true});
  1. Include the library in your project
const mosparo = require('@mosparo/api-client');
  1. After the form was submitted, verify the data before processing it
let client = new mosparo.Client(host, publicKey, privateKey, {});

mosparoSubmitToken = formData._mosparo_submitToken;
mosparoValidationToken = formData._mosparo_validationToken;

client.verifySubmission(formData, mosparoSubmitToken, mosparoValidationToken).then((verificationResult) => {
    if (verificationResult.isSubmittable()) {
        // Send the email or process the data
    } else {
        // Show error message

API Documentation


Client initialization

Create a new client object to use the API client.

 * @param string url URL of the mosparo installation
 * @param string publicKey Public key of the mosparo project
 * @param string privateKey Private key of the mosparo project 
 * @param array args Arguments for the axios request
let client = new Client(url, publicKey, privateKey, args);

Verify form data

To verify the form data, call verifySubmission with the form data in an array and the submit and validation token, which mosparo generated on the form initialization and the form data validation. The method will return a new Promise object that is resolved with the VerificationResult object.

 * @param array formData Array with the form values. All not-processed fields by mosparo (hidden, checkbox, 
 *                       radio and so on) have to be removed from this array
 * @param string mosparoSubmitToken Submit token which mosparo returned on the form initialization
 * @param string mosparoValidationToken Validation token which mosparo returned after the form was validated
 * @return Promise Returns a Promise object that is resolved with a VerificationResult object
client.verifySubmission(formData, mosparoSubmitToken, mosparoValidationToken).then((validationResult) => {
    if (verificationResult.isSubmittable()) {
        // Do your stuff, e.g. sending emails...

Request the statistical data

mosparo also has an API method to get the statistical data for a project. You can use the method getStatisticByDate to get the statistical data. You can specify the range in seconds or a start date from which mosparo should return the statistical data. This method will return a StatisticResult object.

 * @param int range = 0 The range in seconds for which mosparo should return the statistical data (will be rounded up to a full day since mosparo v1.1)
 * @param string startDate = null The Start date from which on mosparo should return the statistical data (requires mosparo v1.1)
 * @return Promise Returns a Promise object that is resolved with a StatisticResult object
client.getStatisticByDate(range, startDate).then((statisticResult) => {
    // Process the statistical data



  • FIELD_NOT_VERIFIED: 'not-verified'
  • FIELD_VALID: 'valid'
  • FIELD_INVALID: 'invalid'

isSubmittable(): boolean

Returns true, if the form is submittable. This means that the verification was successful and the form data are valid.

isValid(): boolean

Returns true, if mosparo determined the form as valid. The difference to isSubmittable() is, that this is the raw result from mosparo while isSubmittable() also checks if the verification was done correctly.

getVerifiedFields(): array (see Constants)

Returns an array with all verified field keys.

getVerifiedField(key): string (see Constants)

Returns the verification status of one field.

hasIssues(): boolean

Returns true, if there were verification issues.

getIssues(): array

Returns an array with all verification issues.


getNumberOfValidSubmissions(): int

Returns the total number of valid submissions in the requested date range.

getNumberOfSpamSubmissions(): int

Returns the total number of spam submissions in the requested date range.

getNumbersByDate(): array

Returns an array with all statistical data for the requested time range. The date is the key in the array, while an array is set as a value. The array contains a key numberOfValidSubmissions with the number of valid submissions and a key numberOfSpamSubmissions with the number of spam submissions.
