Adding a form to an ecommerce site and sending data to Sanity and Stripe

Last updated: Jul 6, 2022
Hey guys, I am admittedly a total noob with the back end. Heck, I am even pretty new to JS in general. I am using React for the first time as well on this project. I have a simple question with hopefully a simple solution. Bonus points if you explain it assuming I am 5 years old. So my issue is this. I currently have an ecommerce shop that sells customizable goods (customizable text, color, etc) all set up through sanity, nextjs, and react... I want to add a simple two or three required text fields form to a product page (probably with react hook form) above two buttons (these buttons pass state to my cart component). I need this form to send the text the customer typed in the field back to the same sanity studio where I push out products to the database (if possible?) so I can view the customer's order requests they input into the form externally (is there a way to have only the successful orders from stripe send back the custom data into the sanity studio?)
Within my ecommerce page is a dynamic single product page where you find the typical things: pictures of product, title of product, description of product all of which are pulled dynamically from the slug. Under the description I have the quantity and then under this I have the add to cart and buy now buttons. The buy now button just adds to cart and opens the cart sidebar component. Within the cart sidebar component there is a proceed to payment button which redirects them to stripes checkout page. This page will redirect them back to either my success or cancel page.

You could setup a webhook in stripe to trigger on successful payments https://stripe.com/docs/webhooks .. Stripe should send your order data in the body of the request, use that to patch in the data into sanity https://www.sanity.io/docs/http-mutations

Thank you so much!!! That actually helps a lot. But how could I collect this data and send it to stripe? I am still a bit confused on how to actually implement the forms for asking what text they would like on their order, etc?

If it helps at all, this is the data structure I mimicked since a lot of this is new to me https://github.com/adrianhajdin/ecommerce_sanity_stripe

Heres a quick way to do in your /product/[slug] page...in sanity create an object for your product options, then patch in the data. You will probably have to return the options object in your stripe.js file too
import React, { useState } from 'react';
import { AiOutlineMinus, AiOutlinePlus, AiFillStar, AiOutlineStar } from 'react-icons/ai';

import { client, urlFor } from '../../lib/client';
import { Product } from '../../components';
import { useStateContext } from '../../context/StateContext';

const ProductDetails = ({ product, products }) => {
  const [options, setOptions] = useState({optionOne: '', optionTwo: ''});
  const { image, name, details, price, } = product;
  product.options = options
  const [index, setIndex] = useState(0);
  const { decQty, incQty, qty, onAdd, setShowCart } = useStateContext();

  const handleBuyNow = () => {
    onAdd(product, qty);


  return (
      <div className="product-detail-container">
          <div className="image-container">
            <img src={urlFor(image && image[index])} className="product-detail-image" />
          <div className="small-images-container">
            {image?.map((item, i) => (
                className={i === index ? 'small-image selected-image' : 'small-image'}

New to JavaScript and React and you chose to make a headless shop? My friend, you are my hero of the day! 😛

LOL well, it all started out by me underestimating the complexity behind processing payments securely. Built an entirely static site that was gorgeous but without a tutorial for all of the backend stuff I was helplessly lost on how to execute what I needed with best practice. So I scrapped my progress and started fresh following a youtube tutorial for this. I have officially gone down the rabbit hole, but I have learned a TON and am so excited to get a better understanding of all the fundamentals now that I seen the whole process in action! Struggling through foreign coding languages has been surprisingly addicting haha

I totally get it. I do the seven stages of grief for every major project but I'm still here so something must be keeping me in the mix!
