Making a Slack bot invite meeting participants to a Google Calendar event. Service accounts cannot add attendees without domain-wide delegation, so the bot authenticates as a real user via an OAuth refresh token and patches the event on that user's calendar copy, with a fallback that never blocks the submission.
When Slack SSO works for staff but not guest accounts: adding Google sign-in as a gated fallback, re-keying users on email, preserving Slack mentions for users who never sign in with Slack, and enforcing who may use which door.
A form sends a URL. The bot decides whether the page lives in a repo it can change, and if so it triggers a CI workflow where an AI coding agent makes a fixed, repetitive edit and opens a pull request, then reports back into the Slack thread. Covers classifying a page via the GitHub contents API, the reusable-workflow pattern, an AI agent in CI, and a secured callback.
A report form sends a URL. The bot normalizes the URL, looks it up in a master spreadsheet to find who owns that page, and @mentions them in-thread, with sensible fallbacks. Covers URL normalization, an efficient bottom-up sheet lookup, and Slack mention resolution including subteam groups.
Parsing a multi-field Slack Workflow form into structured data, appending it to a Google Sheet, posting a review message with an Approve button, and on approval booking a Google Calendar event. Covers form parsing, the Sheets API, Slack interactive buttons, and the Calendar API.
Slack Workflow Builder dropped the outbound webhook action, so a form can no longer call your service directly. Here is how I worked around it by routing form submissions through a private channel that a bot reads, then DMing the requester a computed deadline, all without paying for a third-party connector.
How I built a Slack Workflow integration that lets users submit raw notes, uses Gemini AI to structure them into proper documentation, and automatically creates GitHub PRs for review.
How I added interactive feedback buttons to collect user satisfaction data, log it to BigQuery, and prevent double-clicking with visual confirmation.
Fixing Slack retry duplicates with event deduplication, eliminating Cloud Run cold starts with min-instances, and dealing with cross-region Gemini API latency.
How I automated CDN cache purging through a Slack bot, eliminating late-night manual operations while maintaining security with Slack signature verification and channel restrictions.
How I built a Slack bot that reads Google Calendar events and sends automated weekly reminders with user mentions using Google Apps Script
