Production credentials: Public Key, Access Token, Client ID, Client Secret

Configuration of webhooks in partner:

Via dashboard:
  1. Create an application on the homepage of your Dashboard.
  2. With the application created, go to the Webhooks Notifications tab in your Dashboard and configure the URLs of production and test from which notifications will be received.
  3. You will also be able to experiment and test if the indicated URL is receiving notifications correctly, being able to verify the request, the response given by the server and the description of the event.
  4. If you need to identify multiple accounts, at the end of the indicated URL you can indicate the parameter ?customer=(sellername) endpoint to identify the sellers.
  5. Next, select the events from which you will receive notifications in json format via an HTTP POST to the URL specified above. An event is any type of update to the reported object, including status or attribute changes. See the events that can be configured in the table below.
Setup while creating payments:
  1. In the notification_url field, indicate the URL from which notifications will be received.
  2. Implement the notifications receiver.
If you want to receive notifications only from Webhook and not from IPN, you can add in the notification_url the parameter source_news=webhook. For example:

Note: When you receive a notification on your platform, Mercado Pago waits for a response to validate that you received it correctly. For that, you must return an HTTP STATUS 200 (OK) or 201 (CREATED). If this response is not sent, it will be understood that you have not received the notification and a further attempt to send it will be made until you submit the response.

Production environment

Specific procedure for a merchant to go live:

If the merchant is part of a group of corporations that Mercado Pago follows-up punctually, a call to validate the integration should be made, the test payments in Mercado Pago's system should ve revised, thinking on a progressive roll-out method, etc.
