i have PHP project with laravel(5.4 version) framework so i need to implement SAOP API Yousign(Yousign API process the signature of document ) , so I have download and install this package from Github"YouSign-NodeJS-API-Wrapper" to my project ,i put in config file my credentials and the connection to the api is accomplished ,so I tried to implement function initSignature
initSignature(fileToSignRelativePath, firstName, lastName, email, phone, signatureCoordinates) Inits a signature and returns the url of the signing page
i tried to prepare small test script to this function in js and there’s a code here :
var ysAPIWrapper = require('yousign-nodejs-api-wrapper')
console.log(ysAPIWrapper)
ysAPIWrapper.checkAuth().then(function (response) {
console.log(response)
})
ysAPIWrapper.initSignature('C:/document1.pdf','
hosni','akkeri','info@mail.fr','+3367499750', [
{
rectangleCoords: "351,32,551,132",
page: 1,
document: 1
}
],null,null,null).then(function (response, error) {
yarj3oulna mel Promise
console.log(response)

console.log(error)
