Environment Setup

To begin using the Celar API, choose the correct environment and configure your credentials in the Dashboard.

Celar offers two API environments:

Production (live)
https://api.celar.io/api/v1
Use this for all live transactions.

Sandbox (development)
https://api.sandbox.celar.io/api/v1
Use this for testing integrations and simulating live workflows.

Inside the Dashboard -> Settings, you should:

Set a Webhook / Callback URL to receive real-time payment status updates.
Configure webhook URLs separately for sandbox and production if you use both environments.

Without setting a webhook, you will not be notified of different payment activities on the API.
