Quick start

Five steps from zero to a successful authenticated call.

01
Get your API key
Open Settings → API Settings in the Business Panel and copy a Business or Branch key.
02
Authenticate your request
Send X-API-Key: YOUR_BRANCH_API_KEY (or a Business API Key for business-scoped calls).
03
Choose your business or branch
Use a Business API Key for business-scoped resources. Use a Branch API Key for sales, items, stock, and device workflows.
04
Make your first API request
Start with credit balance or initialize the branch device when required.
05
Process the response
Read JSON status, data, and handle validation or auth errors.

Authentication

Authenticate with the X-API-Key header. Never put real keys in source control — use placeholders like YOUR_BUSINESS_API_KEY and YOUR_BRANCH_API_KEY.

Headers

X-API-Key: YOUR_BRANCH_API_KEY
Accept: application/json
Content-Type: application/json

Business API Key

Authenticates API requests within the scope of the associated business.
Scope: credits, branch list, subscriptions, suppliers, cross-branch inventory summary.
Cannot call branch operations such as sales, items, stock, initialize, or credit notes.
Supplied as X-API-Key: YOUR_BUSINESS_API_KEY.

Branch API Key

Authenticates API requests within the scope of the associated branch only.
Scope: device init, products, inventory, sales, purchases, credit notes, notices, code lists.
