Configuration (Admin)

The store's flat key/value settings — everything under Configuration in the admin (general, catalog, sales, customer, email, payment, shipping, …). Unlike the rest of the admin API, Configuration is not one endpoint per screen: its schema is registered at runtime by every installed package, so the API exposes three generic endpoints that work across any current or future section. Everything is keyed by a slug — a dotted section path like sales.order_settings or general.content.

Agent-ask inputs

• Integration token — ask the user; send as Authorization: Bearer <id>|<token>. Needs the configuration permission (else 403).
• Server URL — ask the user for their Bagisto server's base URL (e.g. https://store.example.com) and prefix every endpoint path with it. Never assume localhost or a demo domain.

The three endpoints

Operation	REST	GraphQL field
Menu (schema)	GET configuration/menu	menuAdminConfigurationMenu
Slugs (discovery)	GET configuration/slugs	listAdminConfigurationSlug
Values	GET configuration?slug=…	valuesAdminConfigurationValues
Update	POST configuration	createAdminConfigurationUpdate

Flow: schema → values → update

• Menu returns the whole tree (sections → groups → fields), each field with its code, type, title, default, validation, and whether it's channel-/locale-based — build the config nav AND know which input control each field needs. ?slug=<section> scopes to one node; ?include_values=true (+ ?channel=/?locale=) embeds values so one call renders a populated form.
• Slugs lists every registered slug so you can discover what to pass to Values/Update without trial-and-error.
• Values returns a flat { dottedCode: stringValue } map for a slug (falling back to each field's default). The slug is required — the endpoint refuses to dump the whole table.
• Update writes a values map for a slug and returns the freshly-resolved values.

Field types → controls

boolean → toggle · select/multiselect → dropdown(s) from the field's options · text/textarea/password → inputs · image/file → upload · color → colour picker · type: "custom" (customView) → read-only over the API (route the user to the admin panel).

Channel- / locale-based fields vary per storefront context — add channel/locale switchers, and pass the matching ?channel=/?locale= (or channel/locale keys in the update body) on read and write.

Two hard rules when writing config

1. Every key must start with the slug. On update, every key in values must be prefixed with that request's slug. (slug sales.order_settings → keys like sales.order_settings.reorder.admin). The server refuses any key that escapes the slug (400) — this prevents overwriting an unrelated section. Build keys from the slug you're editing, never a hand-typed path.
2. File/image fields are REST-only. Config image/file fields upload via a multipart POST /api/admin/configuration with the file in the values[<dotted.code>] part. The GraphQL update rejects file-type fields — use REST for any screen with an upload. Scalar-only updates work over either transport.

Validation is server-side from each field's own rule (not trusted from the client) — a bad value returns 422 with the offending field; show it inline.

Status codes to handle

200 read/update OK · 400 missing slug or a key escaping the slug · 401 unauthenticated · 403 permission · 422 field validation failed (or a file field sent over GraphQL — use REST).
