How to fill PDF Form Field Values in Node.JS

If I told you that setting up a system for filling out PDF forms could be achieved in less than five minutes, you would probably call me crazy. However, I have a secret weapon up my sleeve that allows us to implement advanced features like this in no time at all. Allow me to show you the process.

Here’s a reference to add to your package.json file, allowing the installation of the API client that we will be using.

"dependencies": {
    "cloudmersive-convert-api-client": "^2.1.6"
  }

Next, we call editPdfSetFormFields, shown here:

var CloudmersiveConvertApiClient = require('cloudmersive-convert-api-client');
var defaultClient = CloudmersiveConvertApiClient.ApiClient.instance;
// Configure API key authorization: Apikey
var Apikey = defaultClient.authentications['Apikey'];
Apikey.apiKey = 'YOUR API KEY';
// Uncomment the following line to set a prefix for the API key, e.g. "Token" (defaults to null)
//Apikey.apiKeyPrefix = 'Token';
var apiInstance = new CloudmersiveConvertApiClient.EditPdfApi();
var fieldValues = new CloudmersiveConvertApiClient.SetPdfFormFieldsRequest(); // SetPdfFormFieldsRequest |
var callback = function(error, data, response) {
if (error) {
console.error(error);
} else {
console.log('API called successfully. Returned data: ' + data);
}
};
apiInstance.editPdfSetFormFields(fieldValues, callback);

And there you have it, ladies and gentlemen, our completed solution. This function pairs nicely with editPdfGetFormFields, which will provide the fields available as well as the type of data for each.
