Configure Commerce App Business Config

Adds or modifies the businessConfig.schema array in an existing app.commerce.config.ts. Each entry in the schema defines one merchant-configurable setting that Commerce Admin will render as a UI field. Other extensibility domains (webhooks, events) are added separately via their own skills.

Prerequisites

• Verify the app is scaffolded and initialized, not merely that the config exists. Require both:
  • app.commerce.config.ts present in the project root, and
  • the project initialized — signalled by the generated src/commerce-extensibility-1/ directory and installed node_modules (the @adobe/aio-commerce-lib-app dependency).
• If app.commerce.config.ts is missing, stop and invoke commerce-app-init first (it writes the config, then runs init).
• If the config is present but the project is not initialized (no src/commerce-extensibility-1/ or node_modules), run npx @adobe/aio-commerce-lib-app init before continuing. Init is idempotent — it finds the existing config, skips the interactive prompts, installs dependencies, and generates the project files.

Step 1 — Understand intent

For each setting the user wants to expose, gather:

• Name — machine identifier for the field (used as the config key read by the app at runtime)
• Type — one of: list, text, password, email, url, tel, boolean
• Label (optional) — human-readable label shown in Admin
• Description (optional) — help text shown alongside the field in Admin
• Default value (optional, type-dependent — see constraints in Step 2)
• For list fields additionally: selectionMode ("single" or "multiple") and options (each with a label and value string)

Step 2 — Derive config values

Apply the following per-type validation rules before writing. Surface any issues to the user before proceeding.

businessConfig.schema must contain at least one field — an empty array is rejected at build time.

Step 3 — Update app.commerce.config.ts

Add (or merge into) the top-level businessConfig.schema array, preserving all other domains. If the config already has a businessConfig key, append to businessConfig.schema rather than replacing it.

Minimal examples:

businessConfig: {
  schema: [
    // Password (masked input — API keys, secrets)
    { name: "api_key", type: "password", label: "API Key", default: "" },

    // Single-select list
    {
      name: "region", type: "list", selectionMode: "single",
      label: "Region",
      options: [{ label: "EU", value: "eu" }, { label: "US", value: "us" }],
      default: "eu",   // required; must match an option value
    },

    // Boolean toggle
    { name: "debug_mode", type: "boolean", label: "Enable Debug Mode", default: false },

    // Dynamic list — options resolved at runtime via a factory that receives the action's params.
    // Required `default` factory for single-select; optional for multiple (falls back to []).
    {
      name: "paymentMethod", type: "dynamicList", selectionMode: "single",
      label: "Default Payment Method",
      options: async (params) => {
        const methods = await fetchPaymentMethods(params.SOME_API_KEY);
        return methods.map((m) => ({ label: m.title, value: m.code }));
      },
      default: (resolvedOptions) => resolvedOptions[0].value,
    },
  ],
}

See assets/business-config.ts for the full reference showing all field types.

Step 4 — Register the extension point

Run init so that commerce/configuration/1 is added to app.config.yaml and install.yaml, and the required @adobe/aio-commerce-lib-config dependency is installed. This is idempotent — safe to run even if the extension is already registered.

npx @adobe/aio-commerce-lib-app init

Step 5 — Validate

Build the project to confirm the updated config is valid:

aio app build

A build failure with a validation error points directly to the offending field.

Reading config in runtime actions

Use @adobe/aio-commerce-lib-config to read the values merchants set in Commerce Admin. The library must be initialized with the generated schema on every action invocation before any config call.

Basic pattern

import {
  initialize,
  getConfigurationByKey,
  getConfiguration,
  byCodeAndLevel,
} from "@adobe/aio-commerce-lib-config";
// Schema is generated by `aio app build` into .generated/configuration-schema.json
// under the commerce-configuration-1 extension; adjust the relative path for your action.
import schema from "../../.generated/configuration-schema.json" with { type: "json" };

export async function main(params) {
  await initialize({ schema });

  // Read a single field — config is null if the key has never been set
  const { config } = await getConfigurationByKey(
    "api_key", // the `name` from your schema
    byCodeAndLevel("global", "global"), // scope
  );
  const apiKey = config?.value ?? "";

  // Read all fields for a scope
  const { config: allConfig } = await getConfiguration(
    byCodeAndLevel("global", "global"),
  );
  // allConfig is an array of { name, value, origin } entries

  return { statusCode: 200, body: { success: true } };
}

Scope selectors

Values inherit from parent scopes — a field not set on store_view falls back to store, website, then global.

Password fields

aio app build generates AIO_COMMERCE_CONFIG_ENCRYPTION_KEY automatically into .env the first time it encounters a password field (and validates it on subsequent builds). No manual setup needed.

To decrypt values at runtime, the key must be available to the action. Wire it as an input in the action's ext.config.yaml:

inputs:
  AIO_COMMERCE_CONFIG_ENCRYPTION_KEY: $AIO_COMMERCE_CONFIG_ENCRYPTION_KEY

With the key in place, getConfigurationByKey returns the plaintext value — no extra decryption code needed.

Common Issues

• list/single default missing: Single-select list fields require a default — it can't be omitted. It must exactly match one of the option value strings.
• defineConfig not found: Ensure @adobe/aio-commerce-lib-app is installed and defineConfig is imported from @adobe/aio-commerce-lib-app/config.

Quality Bar

• aio app build completes without errors

Chaining

After aio app build passes:

• Add webhook interceptors — invoke commerce-app-webhooks to intercept Commerce operations before or after they execute
• Add event subscriptions — invoke commerce-app-eventing to subscribe to Commerce or external events
• Extend the Admin UI — invoke commerce-app-admin-ui to add custom columns, mass actions, order view buttons, or menu entries in Commerce Admin
