Error handling: send Slack alert on failure

Trigger a Slack alert when a Kestra workflow fails. A simple, reusable failure notification pattern for monitoring production pipelines.

More Core Blueprints

Automatically purge expired key-value entries from Kestra's internal KV store across namespaces on a daily schedule.

Run scheduled tasks only on business days using a Python calendar check that skips weekends and country-specific public holidays.

Turn plain-English to-do prompts into structured Todoist tasks using DeepSeek AI structured output and a ForEach HTTP loop.

Classify every prompt with OpenAI, then route it to the best-fit LLM across Anthropic, Gemini, Perplexity, and OpenAI for quality and cost.

Cache LLM answers in Redis so repeated questions are served instantly and OpenAI is only called on a genuine cache miss.

A deliberately failing flow that demonstrates block level errors, flow level errors, automatic retries, and KV context for alerting flows.

Use blueprints to kickstart your first workflows.
