Environment Setup

To begin using the Celar API, you’ll need to send requests to the correct environment and configure your credentials in the Dashboard.

Base URL​

All Celar API requests must be sent to:

https://api.celar.io/api/v1

Environments​

Celar offers two environments:

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

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

Webhooks​

Inside the Dashboard → Settings, you should:

  • Set a Webhook / Callback URL to receive real-time payment status updates.

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