Hi,

I'm looking to leverage Alertmanager's functionalities for one of our internal applications, and I'm specifically interested in the webhook receiver to listen for firing and resolved alerts.

I'm interested in getting the unique fingerprint associated with the alert, however I noticed that it is not sent as part of the HTTP POST request as per the config documentation. However, the fingerprint is returned by querying the /api/v1/alerts endpoint, as per this comment. Is there a reason why the fingerprint is not included in the webhook response?

I'll gladly submit a pull request if fingerprints can be added to the webhook response message.

Cheers,
Danny

This was the same query i asked and did not receive any reply. Kindly let me know if you know any solution. Work around is really difficult. It would be great if fingerprint is sent as part of HTTP POST to the webhooks.

The fingerprint is computed from the alert's labels so the webhook endpoint can recompute it if needed.
Changing the webhook data format can impact existing users so it's not free either.

Adding fields is okay, the only impact is the extra bandwidth. Changing fields is not okay.

Thank you both for your answers. If I understand correctly, it seems from Brian's response that adding the fingerprint field to the webhook data would not negatively impact existing users, apart from the extra bandwidth it incurs.

In your opinion, is adding the fingerprint something that would have enough value to justify a change, or should I stick with Simon's proposal of generating the fingerprint from the labels?

Cheers,
Danny
