Create a new Webhook subscription

📘

Webhook & Sandbox

If you are testing the API, you only have access to the Sandbox environment. You are limited in the webhooks creation: you can create Webhooks only from the application, and not from the API.

Once you have access to the production environment, if you want to continue carrying out tests including Webhook notifications, you can create a Webhook Subscription with the environment set to sandbox.
You will receive the same Webhooks you would receive in Production, the only difference will be the parameter sandbox which will be equal to true
