API Documentation

Shorten links straight from your code. One endpoint, one bearer token.

Endpoint

POSThttps://preprod.za.gl/api/shorten
RESTJSON bodyBearer auth

Authentication

Pass your API token in the Authorization header as a bearer token. Grab it from your account dashboard after you create your first link.

Header
Authorization: Bearer YOUR_API_TOKEN

No token yet? You can call the endpoint without one. Za.gl creates an anonymous account on the fly and returns a fresh token in data.newAuthToken. Save it to manage your links later.
