A first read · GET /v1/clients

curl "https://api.omnizone.app/v1/clients?limit=5&offset=0" \

JSON responses · Bearer authentication · Workspace-scoped access

Set OMNIZONE_API_KEY in your server environment. This read-only example lists up to five clients.

Connect business records

Work with clients, invoices, bills, and accounts. Use the documented endpoints to link your own back office or reporting tools.

Browse available endpoints

Build your workflow

Call the API from your server or integration service. The OpenAPI specification lists supported methods, request schemas, and responses.

Keep access intentional

API keys belong to a workspace and follow their assigned role and permissions. Plan limits apply; keys can expire or be revoked.

Review plans and API access

Headless storefront

Storefront API

Every shopper action — catalogue, cart, checkout and account — is available as REST with a store publishable key. The same operations power shopper MCP tools on the store host. Card data never appears in the API; pay through the hosted payment link.

A small first step

Connect. Check. Then build.

Create a key
Open Settings → API keys in your workspace. Choose the appropriate role and keep the secret on your server.
Confirm the workspace
Call GET /v1/me to check the workspace and plan associated with your key before reading or writing business records.
Start with a read
Fetch a small list of clients. Then consult the reference for the resources and permissions your integration needs.

Check your connection · GET /v1/me

curl "https://api.omnizone.app/v1/me" \
  --header "Authorization: Bearer $OMNIZONE_API_KEY"

Missing, expired, or revoked keys return 401. Insufficient permissions or plan access can return 403. Handle rate limits with retries and backoff.

MCP & AI integrations

Give your AI tools a controlled way in.

Omnizone hosts a remote MCP server over Streamable HTTP. Add https://api.omnizone.app/mcp as a custom connector in Claude or Cursor to sign in with OAuth (no pasted keys), or use a workspace API key (ozk_…). Tools mirror the public REST catalog — the same role ∩ plan ∩ catalog gates as /v1.

Every tool call is audited with secrets redacted. Prefer a read-only role key for assistants that should not create or update records.

Create a workspace API key
Settings → API keys. Use a role that matches what the assistant should see.
Add the MCP server URL
Use https://api.omnizone.app/mcp with Authorization: Bearer and your key.
List tools in MCP Inspector
Initialize the session, then tools/list. Write tools are omitted when the key cannot perform that action.

Example tool: list_clients → GET /v1/clients. Resources expose JSON schemas; prompts cover common operator tasks.

Client setup

Claude and Cursor

Paste the server URL into your MCP client config. Keep the key in an environment variable — never commit ozk_live_ or ozk_test_ secrets.

Local Wrangler serves /mcp on the same origin as the SPA. Production uses the API host only.

Connected assistants

One MCP URL. The token chooses the mode.

Workspace and store assistants both use https://api.omnizone.app/mcp. The token is bound to one workspace. A store token is also bound to one store. Arguments that name another workspace or store are rejected.

The token dialogs in Settings → Connected apps and Commerce → Connected assistants show this same URL. Your workspace address does not serve /mcp.

Token or OAuth

Paste a token
Settings → Connected apps for the whole workspace, or Commerce → Settings → Connected assistants for one store. The secret is shown once. Send it as Authorization: Bearer.
Or sign in with OAuth
The client discovers the API host, then opens /oauth/authorize and exchanges the code at /oauth/token. On the consent page choose the whole workspace or one store, and the store tool set. Refresh tokens stop working when the connection is revoked.

What each profile exposes

workspace_readonly
Reads the public REST catalog. Write tools are omitted. Refused on anything except GET and HEAD under /v1.
Tool groups: merchant_read
workspace_role
Reads and writes follow the workspace role on the key. tools/list is the schema.
Tool groups: merchant_read, merchant_write
store_assistant
Store tools only: browse, cart, or the full set. The same token cannot call /v1.
Tool groups: store_assistant

Verification

Customer tools stay closed until the phone or email matches that order on this store, or a code is verified. Methods: order_phone, otp. send_verification_code does not return the code.

Notifications

One notification URL per connection. The signing secret is shown once. A workspace connection can subscribe to product.created, product.updated, product.deleted, stock.changed, order.placed, order.paid, order.cancelled, shipment.updated, return.created, return.updated, customer.created, cart.abandoned. A store connection only receives order.placed, order.paid, order.cancelled, shipment.updated, return.updated, cart.abandoned.

Errors

unauthorized 401
Missing, expired, or revoked token.
scope_forbidden 403
The arguments name another workspace or store, or a store token called /v1.
rate_limited 429
The connection is over its request limit. Retry after the hint.
connected_assistants_limit 402
This plan has no room for another assistant. The response includes the plan comparison.
verification_required
Customer data stays hidden until this conversation is verified.
checkout_over_max
The cart is over this connection's checkout maximum.

Interactic

Create the connection
Workspace: Settings → Connected apps. Store: Commerce → Settings → Connected assistants. Name it, then copy the token. It is not shown again.
Add the Omnizone server
In Interactic, open the agent, then MCP tools, and add a server. URL https://api.omnizone.app/mcp. Header Authorization: Bearer and the token. Interactic is at https://interactic.app.
Or use OAuth
Skip the pasted token. When Interactic starts the sign-in, pick the whole workspace or one store on the consent page.
Check the tools
MCP Inspector: initialize, then tools/list. A read-only workspace profile has no writes. Browse has no cart.

Claude, Cursor, and MCP Inspector

Claude
Add a custom connector with https://api.omnizone.app/mcp. OAuth signs in, or set Authorization: Bearer from an environment variable.
Cursor
The mcp.json block above uses the same URL. Keep the token in an environment variable.
MCP Inspector
Streamable HTTP, initialize, then tools/list, then tools/call. A store token lists only that store's tool set.

Shopper assistants

Shopper MCP on the store host

Each live store publishes Streamable HTTP MCP at /mcp on the store address — not the merchant MCP on the API host. Connect Claude, ChatGPT, Cursor or a custom agent to that URL. Shopper OAuth (PKCE) issues shopper tokens. Assistants never receive card numbers; checkout is prepare_checkout then a hosted payment link or COD.

The same catalogue, cart, checkout, orders, addresses and wishlist run through the Storefront API. Turn the assistant on or off in Commerce → Settings → AI agents.

Open the store /developers page
It lists every tool schema, OAuth URLs, and a sample purchase. MCP Inspector: initialize, then tools/list.
Add the store MCP URL
Claude, Cursor mcp.json, ChatGPT custom GPT, or any Streamable HTTP client. No merchant API keys.
Complete shopper OAuth when asked
Guest tools browse and fill a cart. Account, checkout and orders need the shopper token.
