Payment Gateways

Stripe Subscriptions Integration with Payment Intents API

For the last couple years we with the team have built tons of different payment integrations for our clients. In this tutorial I would like to share with you my experience of developing Stripe subscriptions integration for WordPress (or pretty much any PHP website).

I am also going to use modern Stripe Payment Intents API in this guide. If you want to learn a little bit more about payment intents and why it is so cool to use them, I recommend to take a look at my another tutorial.

In order to make this tutorial simple I included only the very basics which are necessary to make the subscriptions work. Please don’t forget about validations, processing errors and protection against card testing attacks for example. If you need some help with it, you can always contact us and we will develop everything for you the best possible way.

And now let’s dive into the tutorial!

The thing is that it is obsolete right now. Well, it actually works for some cards, but mainly for those cards that are operating in North America. Today our goal is to implement it with brand new Stripe API which is called Payment Intents.

And I am going to guide your through it step by step.

How to Validate Payment Gateway Settings Fields

It seems like my complete payment gateway tutorial is not that complete after all. I didn’t mention there how you can validate payment gateway admin options.

For example let’s assume that we have to validate a USDT address of a TRON network. Here is how it should work:

Let’s assume that we’ve already added a field for a USDT address inside init_form_fields() method. Just like that:
