Working with Events and presignedUrl

4 min
Events and presignedUrl requires partners to provide webhook for Klavi event reception, and proactively obtain analysis result files based on the presignedUrl in the event.
1.Configure the webhook for event reception
Partners need to configure the following information in the Console:
Webhook for event reception
The above information can also be provided to Klavi business personnel for Klavi to fill in.
2.Passive reception and parse events through webhook
After Klavi completes the data analysis, it will send notifications to the configured webhooks.

The default lifecycle of presignedUrl is 7 day, starting from eventTime. Partners need to complete file retrieval before the end of the lifecycle, otherwise the URL will become invalid.
