API overview - BillingServ

The BillingServ API lets your application manage customers, packages, invoices, orders, support tickets, usage, reports, and other supported account resources.

Base URL

Use your BillingServ installation’s v2 API URL:

https://your-billingserv-domain.com/api/v2

API v1 is deprecated. New integrations should use v2.

Authentication

Generate a live API key from Admin → API Information, then send it as a bearer token:

Authorization: Bearer <live_api_key>
Accept: application/json

The full key is shown once. Store it securely and never expose it in browser code, logs, or a public repository. Regenerating the key invalidates the previous key.

curl "https://your-billingserv-domain.com/api/v2/customer/lists" \
  -H "Authorization: Bearer <live_api_key>" \
  -H "Accept: application/json"

Request and response format

Send JSON for request bodies unless an endpoint documents another format:

Content-Type: application/json

Successful responses contain "success": true. Errors use the relevant HTTP status and include an error message or validation errors.

Status	Meaning
`200`	Request completed successfully
`401`	API key is missing or invalid
`403`	The authenticated account cannot use the endpoint
`422`	Request validation failed
`429`	Rate limit exceeded

Keep your system synchronized

Polling the API is not required for every change. Configure webhooks to receive customer, payment, invoice, order, subscription, credit note, and support events as they happen.
