I was trying to authenticate to Azure DefaultAzureCredential using @azure/identity in Node js to get the reports of Azure API Management Service.

Things I have done :

1. Created An API Management Service from Azure Portal

2. Registered an application with Azure AD and create a service principal using this documentation.

3. I Have configured environment variables correctly to use DefaultAzureCredential as mentioned in this documentation.

   AZURE_TENANT_ID, AZURE_CLIENT_ID, AZURE_CLIENT_SECRET, AZURE_SUBSCRIPTION,

But the authentication is getting failed and I am not able to generate credentials. when I consoled the new DefaultAzureCredential(); response, it says that UnavailableMessage: 'DefaultAzureCredential => failed to retrieve a token from the included credentials',

I'm developing a website with Nuxt + Node + Express and I'm trying to implement PayPal. I'm using PayPal Node SDK and I created the files just as described in their Github page. I'm developing in my pc (so, localhost..) and using PayPal Sandbox.

The problem is: it works perfectly for the first time. I click the 'Buy' button in the frontend, I'm redirected to PayPal payment page, I pay using Sandbox account, then I'm redirect to my website again with the TOKEN in the URL. The output from the call to the backend API is 'COMPLETED'. BUT, if I login with another user, clear browser cache or even change the browser, and try to BUY again it says that: "Order already captured". After a few hours I can buy again. The only thing that works is RESTARTING the server. I've checked if there's some cookies in the server with cookies-parser but there isn't.

Call anyone help me understand why it happens?

Here is the files/code I used:

Created the paypal_controller.js with:

I'd like to get a subscription information from the subscription API endpoint

/v1/billing/subscriptions https://developer.paypal.com/docs/api/subscriptions/v1/#subscriptions

It requires an auth bearer token, and I don't want to spend weeks setting up an auth handler. Paypal's current repos doesn't support subscriptions endpoint (or most others TBH...): checkout SDK and payouts SDK

These probably have some auth wrapper but I'm struggling to determine how to use it to make fetch() calls from my server to the subscriptions endpoint, does anyone have a solution they've used?

FYI: I'm using paypal smart buttons to create a subscription and then making an api call with subscription id to add details to user in DB

I'm new to Square and want to implement it in a React Native app with a Node backend.

I see that there is a method to save the customer's card details. https://github.com/square/square-nodejs-sdk/blob/master/src/api/customersApi.ts#L230

But there is also the payment form? https://developer.squareup.com/docs/payment-form/how-it-works

Firstly, I cannot see if the payment form is even available in React Native - information seems very scarce.

Secondly, even if I do implement that form, I can't see a way to connect it to the customers API endpoint.

I don't want to use in-app payments (i.e. google or apple pay). I want to be able to save card details like Amazon does, and use them whenever a user places an order in app (probably triggered by a node process). I'm not sure if I'm going about this the correct way, guidance would be appreciated.

I am currently working on react js project where I need two main functionalities of Paypal one is to make payment and other is to make a refund on that payment ( sometimes partial refund on a subset of that payment).

I am following this sdk of the node.js implementation, https://github.com/paypal/Checkout-NodeJS-SDK

but I want to extract the transaction ID and token and such details which I am not able to find in this SDK.

I am just getting the order ID capture ID refund ID but not the transaction ID , so how do I get that ?

also , I am suggested to use smart payment buttons but if I am using the smart payment buttons, I am able to perform the checkout operation,but getting different set of details like

payment ID , payment token and I don't know how to perform the refund for that payment?

I am using Firebase functions to process credit cards through square. My function works great for successful card transactions. However, with card errors such as declined or incorrect cvv, I want to send that error context to the user. What happens with my current code I just get an error 500 from the cloud function. When I look at the function logs, it has an Unhandled error { Error: Bad Request... I can see the desired text in the log but this doesn't get passed to the front end. Here is my current code.

I'm using PayPal Checkout API SDK and I successfully created an order using the smart buttons, so when the user click on the paypal button an order is created. Here's my code for the final capture:
