Notification callbacks
Besides webhooks, Getnet provides callback-based notifications: the server calls URLs you provide (callbacks) to notify your system about payment events. This mechanism uses HTTP GET requests with data in the query string and is configured at accreditation time. It is distinct from the webhooks offered in the Regional API, which use HTTP POST, configurable subscriptions, and a different payload format.
To set up GetNet’s notifications via callback, you must state 4 URLs at the time of your accreditation on the Digital Platform. Each one will be destined to receive different notifications of the following types:
- Credit transactions,
- Debit transactions,
- Bank payment slip transactions (boleto),
- Recurring transactions (subscription)
Once the callback URLs are set up, GetNet will automatically send the relevant data to each URL when the specified event occurs. In the event of an error, the information will be resent every 15 minutes up to 4 times.
We always recommend keeping an eye on the certificate expiration date for each URL. In case of renewal or if you need to modify any of the originally stated URLs, please contact our GetNet Integration Support Team.
Notifications structure
In general terms, the HTTP requests have the following structure:
https://YOUR_HOST_EXAMPLE/YOUR_SERVICE_EXAMPLE?query_param_1=valueExample1&query_param_2=valueExample2
Where:https://YOUR_HOST/YOUR_SERVICErefers to one of the 4 callback URLs previously stated.?indicates the beginning of the query section.query_param_1=valueExample1is an example of a query parameter.&is used as a connector between multiple query parameters.
The HTTP GET notifications provided by GetNet will include a specific set of query parameters, some of which are shared across different trigger events, while others are unique and specific to a single trigger event.
