I'm building a NodeJS API + Android/IOS Apps connecting to that API.
Additionally, I have a Shopify store where customers register and purchase products.
Now, I need to set up auth flow on these mobile APPS, which will redirect to the Shopify store, authenticate using customer account credentials, allow that customer to log in with APP, and allow API access with that authentication.
API Auth layer developed with JWT authentication for the moment which is working without shopify interaction.
Is there anyone who has done something like this with Shopify customer accounts?

We are building SAAS platform like Shopify. Now we would like our customers to install MailChimp on their store just like Shopify customer installs on their store.
When I was trying MailChimp on Shopify platform, i noticed somehow Shopify receives some key/token from MailChimp when installation completes and then Shopify uses this key/token to update MailChimp list of that store whenever some events occurs. That's what we are looking to build.
I tried MailChimp API (on Playground) with the generated key. But, this API creates store, list etc under my account, then how do i enable this against our customer's MailChimp account?
I would greatly appreciate it if you kindly give me some feedback.
Both Shopify and MailChimp use OAuth to exchange API credentials for users accounts between each other.
In your case, you should probably check out MailChimps OAuth 2 documentation on this topic.
When it comes to integrating MailChimp with your SaaS, your application as to acts as a client to MailChimp. Use OAuth to let your users connect their MailChimp account to your application and store the Refresh and Access Tokens in your database. This allows you to make requests to the MailChimp API to access your user's MailChimp data.
I am working on a project to upgrade an existing payment processing tool, which is using paypal's classic NVP api. Now, I need to program a whole new system that uses the PayPal's REST API and the two systems should share the same paypal account. Here is the question--if I create a REST API credential, will paypal disable my old classic NVP/SOAP API's key (or credential)?
You can use both at the same time without any problem.
I want to generate pay request in paypal using Paypal Api. I am using the following
reference link https://www.x.com/developers/paypal/documentation-tools/api/pay-api-operation
But they people have not explained how to use that code in c#. I want to give a button to user and he'll fill the oauth key and payment request will be sent to merchant account.
Please suggest
