Want to integrate payment gateway in which a post request has to be made to the gateway server.In inline php it works easily as the post request is made from html form to php to gateway server. But how would i carry this out in angular and node. Should I send a request from angular to node and then from node to gateway server?
You can check different payment gateway documentation depending upon the one you want to integrate. Here is stripe documentation

I need some help with PayPal notification integration (react/laravel).
I need to receive notification to my backend every time a client checkout with PayPal successfully.
Is there any way to implement this?
IPN is very old and nearly deprecated, there is no reason to use it with the current PayPal Checkout.
To implement the current PayPal Checkout, follow that guide and make two routes (url paths) on your server, one for 'Create Order' and one for 'Capture Order'. You can use the Checkout-PHP-SDK for the routes' API calls to PayPal, or your own HTTPS implementation of first getting an access token and then doing the call. Both of these routes should return/output only JSON data (no HTML or text). Inside the 2nd route, when the capture API is successful you should verify the amount was correct and store its resulting payment details in your database (particularly purchase_units[0].payments.captures[0].id, which is the PayPal transaction ID) and perform any necessary business logic (such as sending confirmation emails or reserving product) immediately before forwarding your return JSON to the frontend caller. In the event of an error forward the JSON details of it as well, since the frontend must handle such cases.
Pair those 2 routes with this frontend approval flow: https://developer.paypal.com/demo/checkout/#/pattern/server . (If you need to send any additional data from the client to the server, such as an items array or selected options, add a body parameter to the fetch with a value that is a JSON string or object)
Do not use the deprecated PayPal-PHP-SDK, which is for the deprecated v1/payments API
since i was struggling in making API calls to apache server from my angular app running in node-express,
So i was unable to call apache server with POST calls inspite of setting the CORS filter in most of the ways available,
So someone suggested rather of making calls from AngularJs(Frontend) , make it from NodeJs(Backend-server) which serves your angulas(frontEnd) code.
So kindly assisst me in this as to what exactly is the difference between making API call's from frontEnd to any server or from the backend(server) of the same frontEnd ??
What factors makes it more preferable over the other one ?
Is it proxy or CORS thing which effects FrontEnd based API calls ?
Thanking all in advance

CORS is a policy that is voluntarily enforced by the browser (chrome, firefox, etc.). The decision to allow or deny a request is based on the presence of a certain header (Access-Control-Allow-Origin: *) in a response from the server. There is no equivalent policy in a server side setting, so you are free to make cross-origin requests all day.
From enable-cors.org:
[CORS] prevents JavaScript from making requests across domain boundaries
This is why I usually build a small server api in Node to grab data from external 3rd party servers.
When the user makes a request on the front end the request is sent to the backend function with optional parameters which the end-user specified.
Depending on the parameters supplied, different functions might be run before the backend queries the third party API.
3rd party API response is returned to the backend.
Backend either passes the response along or does more stuff before passing the response along.
Then the frontend does stuff with the data based on the response received (ie there were less than 5 results so adding pagination is not necessary).
If developed this way you gain access to the following which all benefit your application/website.
Keep any necessary credentials on the server. ( extremely important )
Obtain logs.
Validate on both the server side and the client side for an added layer of security.
Use the server to filter sensitive results if necessary before they reach the frontend.
Vary which parts of the heavy lifting are done on the server vs the device in order to improve the application performance.
I am developing an app using AngularJS and NodeJS. Being new to both I am struggling a bit.
My app is communicating with payment gateway to facilitate payments. Flow goes like MyApp-->Payment Gateway --> MyApp. I am able to send the request to payment gateway. Problem is I am not able to figure out how I will handle response that is coming from payment gateway. Payment Gateway is sending some data in the post request. I need to process this data before showing results of transaction to user.
Technically speaking I know what needs to be done. Like Step 1) Giving a return URL to Payment Gateway to which Post request will be sent. Step2) This HTML URL of my application will send data received from payment gateway to server side for processing. Step3) Based on processed results I will show transaction result to user.
Where I am struggling is show to achieve this using AngularJS and Nodejs. Pls help
You can use Angular's $http service to easily send and get data from server.
I need to develop a web-based service on Google Appengine (Python 2.7) that involves the sending of sensitive data from a third-party website over to my site (preferably through SSL). Say that my url is https://example.appspot.com, and I want the third-party site http://example.com to send two values through a POST request, one is username and the other is password, to https://example.appspot.com/receiverhandler. This receiver handler is class ReceiverHandler(webapp2.RequestHandler). My question is basically: how can I send this POST data through an SSL connection? I'm not entirely familiar with the SSL protocol, so I have no idea where to begin.
Using urlfetch, just send it to the SSL-secured url: https://example.appspot.com/receiverhandler
This gives great explanation of how to do it, using POST params (payload):

I started using google API recently . I am using simpleauth https://github.com/crhym3/simpleauth for authentication to google app engine . Now I am using google blogger API for publishing my blog and fetching data .
This API requires access_token value to use the API https://developers.google.com/blogger/docs/3.0/using#RetrievingPostsForABlog for Authorization . I cant find a way to get value of access token .
Is there a way to get the value of acces token or am I doing something wrong ?
You need to register your webapp with Google to get a client ID and client secret. Then, you can configure your OAuth2 library with these details to allow you to send fully authenticated requests from your webapp to Blogger.
For the specific scenario you listed, retrieving a blog post, I think you can follow step 1 of this page and then follow these steps. You should be able to copy+paste the key from there into the query params of the GET request.
To issue fully authenticated requests, for publishing new posts, for example, you'll have to get your OAuth2 library with the client ID and client secret and have it issue the requests for you.
