Building Abandoned Checkouts App using Saleor CLI


By now, you know how to install the template App into Saleor Cloud. Now, you are ready to build its new features. This guide will show you a rather simple workflow of building new functionality for your App. Yet, it is a good starting point for developing more complex things.

What will I learn?

After finishing this guide, you'll have accomplished the following:

  1. Added a GraphQL query.
  2. Updated permissions for the App using Saleor CLI command.
  3. Generated types and hooks for the query.
  4. Created a simple UI using a generated hook.

What will I build?

You will extend the Saleor template App. The App will fetch data from the store about checkouts that for some reason haven't been turned into orders. Such unfinished transactions are usually called abandoned checkouts, and that's going to be the name of your app. You want to display the checkouts id and date of creation in a list.


  1. Before installing the App, add the extensions data to api/manifest.ts file:
extensions: [
		label:  "Abandoned Checkouts",
		target:  "APP_PAGE",
		permissions: ["MANAGE_PRODUCTS"],
		url:  "/abandoned-checkouts",

Heads up!

Make sure the App you want to develop is installed and activated in Saleor Cloud. It is the only context in which the App is functional. So, you develop the App locally but can see the results only in the Dashboard, not the localhost. You may find the instructions for installing an App in Creating Apps with Saleor CLI guide.

  1. The App fetches data that is not present in the Saleor example database by default. Hence, if you want to see the results of the query, it is best to go to your environment GraphQL Playground and insert a few entities of checkout:
mutation CheckoutCreate {
    input: {
      channel: "default-channel"
      email: ""
      lines: []
  ) {
    checkout {
    errors {

You can read more about Saleor GraphQL Playground in the docs.

Step 1. Updating permissions for the App.

Since the template App doesn't have the permissions for managing checkouts, every attempt to query checkouts will fail. Hence, we need to update the permissions to enable querying Saleor for the data:

  1. In your terminal type in saleor app permission set.
  2. Choose the environment and the App name.
  3. Navigate to MANAGE_CHECKOUTS permission using arrow keys.
  4. Press the space key to select it.

Step 2. Adding GraphQL query.

It is time to create the query. Remember that the fastest way to build and test queries is by using the Saleor GraphQL Playground. The link to your App's GraphQL Playground in provided in the .env file of your App.

  1. Create a FetchAllCheckouts.graphql file in graphql/queries folder.
  2. Copy and paste the query below:
query FetchAllCheckouts {
  checkouts(first: 10) {
    edges {
      node {
        lines {
          variant {
            product {
              thumbnail {

Step 3. Generating types and hooks for the query.

Let's use GraphQL Code Generator to produce the types and hooks which will then be used to build the UI. In the Terminal run:

pnpm run generate

After it has been generated, you may inspect the newly created useFetchAllCheckoutsQuery hook in the generated/graphql.ts file.

Step 4. Building the UI.

To provide the list of fetched checkouts let's use the Material UI components, which are pre-installed in the template App. We will present the data in a form of a simple table:

  1. In the pages folder create a new file called abandoned-carts.tsx. and paste the code below:
const AbandonedCheckoutsPage: NextPage = () => {
  const [{ data, error }] = useFetchAllCheckoutsQuery();

  if (!data?.checkouts) {
    return <div>Loading...</div>;

  if (error) {
    return <div>{error.message}</div>;

  return (
      <h1>Abandoned Checkouts</h1>

        {data?.checkouts.edges.length > 0 ? (
          <TableContainer component={Paper}>
            <Table aria-label="checkouts table">
                  <TableCell>Checkout Id</TableCell>
                  <TableCell>Created At</TableCell>
                {, i) => (
                  <TableRow key={}>
                    <TableCell>{i + 1}.</TableCell>
        ) : (
          <div>No data to display...</div>

export default AbandonedCheckoutsPage;

In the above code, we utilised useFetchAllCheckoutsQuery() to pull data from Saleor. Then, we created a table with three columns: No., Checkout Id and Created At. and iterated over the nodes to display the data in each row.
