Has anyone implemented paypal with CB?

[Mert Öztürk]

Hello,

I am searching for a Paypal integration example with CB or is it possible to be done?

Thanks

Mert

Hi Mert,

 

I think there is a REST API for PayPal.

 

If you need REST client examples you can go easily to kivra's restclient https://github.com/kivra/restclient

 

 

Cheers,

Ibrahim.

Hello,

I just could not succeed adding restc application to my cb app.

When  i add "{restc, ".*", {git, "git://github.com/kivra/restclient.git", {tag, "0.3.0"}}}" as rebar dependency on rebar.config, and compile it, it just doesnt work.

application:start(restc) outputs the error with its deps app hackney: {error,{not_started,hackney}}

Do i have to get deps of restc to boss deps folder and recompile it?

Thanks

That means you need to start hackney first with application:start(hackney)

Hello Jesse,

Forgot to mention. It is the deps folder of restc app and when i type application:start(hackney) i got the following: {error,{"no such file or directory","hackney.app"}}

Thanks

Oh gotcha. You want to 'rebar get-deps' and 'rebar compile' from within the root of your CB app.

With hackney in the deps directory of your restc app, it's not going to be recognized by the parent app.

I recompiled with rebar get-deps compile but didnt work again.

restc app is something like below;

restc deps

   - erlsom

   - hackney -------------------------hackney deps

                                                 - idna

                                                 - ssl_verify_hostname

   - idna

   - jsx

   - mochiweb_util

   - ssl_verify_hostname

I can see that they are compiled well and ebins are not empty.

And i cant start with application:start(restc)

Do i have to make changes in boss.config?

Or should i sub-deps of restc and add them manually by one by one to work hackney first and then the restc?

First time of adding an extra library with deps in it so i couldnt figure out how to do it correctly.

Thanks

Mert

All of those deps you see in the restc app *should* be in your CB app's deps directory, at the same level as boss, erlydtl, boss_db, etc.

The deps within deps/restc/deps are outright ignored by erlang.

Well bad news is hackney doesn't work with https connection as they wrote "it works". I searched a bit and they had many issues with connection failures.

Can you guys suggest any advice for making REST calls for to use Paypal (https) ?

Good news is i can now add libraries to my app :)

Thanks

I'm pretty sure I use ibrowse, but when I get back, I'll let you know. I can probably share some paypal code from my work-in-progress payment framework for Nitrogen.

First thing i tried was ibrowse but it also can not make a rest call to a website with https.

Thanks

Update: restc and hackney worked fine with latest Erlang OTP 18.3;

Hello Jesse,

I have implemented a token request with https://github.com/kivra/oauth2_client which is also using restc and it is ok.

Do you have something in mind about making a payment call with restc. I just couldnt figured it out how to put variables in correct form to send REST call.

Trying to implement the call below with CB;

curl -v https://api.sandbox.paypal.com/v1/payments/payment \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer Access-Token" \
  -d '{
    "intent":"sale",
    "redirect_urls":{
      "return_url":"http://example.com/your_redirect_url.html",
      "cancel_url":"http://example.com/your_cancel_url.html"
    },
    "payer":{
      "payment_method":"paypal"
    },
    "transactions":[
      {
        "amount":{
          "total":"7.47",
          "currency":"USD"
        }
      }
    ]
  }'

Hi Mert,

Sorry for falling off the world for a bit there.

Here's my paypal code: http://pastebin.com/0ybSKHkG

Here's the code I use for Paypal with its IPN (Instant Payment Notification) system.  I haven't used paypal with oauth2, so I'm not sure what it takes to do that.

This module (for Nitrogen, so it has some nitrogen element records in it, but easy enough to figure out) generates a basic HTML form (ppb_paypal_nitro:form/6) that submits to the paypal server.

When the payment is processed, the paypal servers make a request to https://mywebserver/ppb_paypal_nitro with whatever data paypal sends. This request ends up running the ppb_paypal_nitro:main() function, which ends up running ppb_paypal_nitro:process_ipn().  This is where I call the server, and hilariously, I'm just using httpc, the built-in Inets client in Erlang.

Functions that might not be familiar to you here are:

wf:q(atom) - Request a POST or GET value

wf:request_body() - Retrieve the entire POST request body in raw form.

ppb:process_payment() is purely a side-effect thing, so the implementation is unnecessary.  It basically just calls a callback to update the database that a payment was received.

Hopefully this helps a bit,

-Jesse
