Starts on a Rss Feed Read event

Quick overview This workflow watches your blog RSS feed for new posts, sends each post URL to Canvora to generate branded social image formats (and an optional carousel), polls until generation completes, and posts the resulting image links to a Slack channel for review. How it works Triggers when a new item appears in the configured RSS feed on an hourly polling schedule. Builds a Canvora generation request using the blog post URL plus your selected output formats, optional carousel settings, language, and brand kit ID. Creates the generation in Canvora via its API. Polls Canvora every 30 seconds to fetch the generation status until it completes, fails, is cancelled, or times out after about 10 minutes. If the generation succeeds (completed or partial), sorts the returned assets and formats a Slack message containing the public file URLs and an edit link. Posts the message to the chosen Slack channel for human review, or sends a Slack alert if the generation fails or times out. Setup Create a Canvora account and add an API key as an HTTP Header Auth credential (header name X-API-Key). Update the RSS Feed Trigger with your blog’s RSS URL.

Draft and stage LinkedIn re-engagements with HeyReach, Twain, and Slack

Quick overview This workflow runs weekly (or manually) to pull tagged “cold” HeyReach conversations, uses Twain to draft context-aware re-engagement messages, then stages leads in a HeyReach list and notifies Slack for review while tagging processed leads to avoid duplicates. How it works Runs on a weekly schedule or via a manual trigger. Fetches all conversations from the HeyReach Inbox API using pagination. Filters conversations by HeyReach lead tags (include tags like “Cold”/“Not interested” and exclude tags like “Re-engaged”) and extracts each lead’s LinkedIn URL, name, and prior message thread. Sends the conversation context to Twain to generate a re-engagement sequence draft and add the contact to the specified Twain campaign. Adds the lead to a HeyReach re-engagement list and stores the first Twain draft message in a custom user field. Posts the drafted re-engagement message to a Slack channel for review. Tags the lead as “Re-engaged” in HeyReach to prevent reprocessing. Setup Add HeyReach API credentials for HTTP Header Auth and ensure the header matches HeyReach requirements (for example, X-API-KEY). Add Twain API credentials for HTTP Header Auth and ensure the header matc

Post a daily Asana project status digest to Slack

Quick overview This workflow runs every weekday morning to fetch tasks from a specified Asana project, bucket them by due status and completion activity, and post a Slack Block Kit digest with counts, key task links, and per-assignee open workload. How it works Runs on a weekday-morning schedule. Pulls tasks from a chosen Asana project via the Asana REST API, including assignee, due date, completion status, and task links, and paginates through results as needed. Groups open tasks into overdue, due today, due this week, and unassigned buckets, and also collects tasks completed within the configured lookback window. Calculates summary counts and open-task load per assignee. Formats the results into a Slack Block Kit message with a short totals line and up to five linked tasks per bucket. Posts the digest to the specified Slack channel. Setup Add an Asana Personal Access Token (Asana API credentials) and select it for the HTTP request that fetches project tasks. Add a Slack OAuth credential and ensure the app/bot can post messages to your target channel. In the configuration step, set your Asana project GID, Slack channel ID, timezone, and the lookback window for recently completed t

Send monthly real estate market summaries to Slack with Supabase and Rentcast

Quick overview Youtube Video: https://youtu.be/zJlncb1T074?si=fnKE7SPh7I-JGdmx This workflow runs monthly for a configured ZIP code, checks Supabase for recent market rental and sales records, and either reports the existing stats or pulls fresh data from the Rentcast API, upserts it into Supabase, and posts a formatted market update to Slack. How it works Runs on a monthly schedule and sets the target ZIP code to analyze. Queries Supabase tables for rental and sales market records for that ZIP code that are older than the start of the current month. If existing data is found, calculates month-over-month changes from the stored history and posts a Slack update (or an admin error message if the history is insufficient). If no current data exists, fetches the latest rental and sales market statistics from the Rentcast Markets API. Upserts the fetched rental and sales statistics (including history and summary fields) into Supabase using the REST endpoint. Calculates month-over-month changes from the newly fetched history and posts a Slack market summary, or posts an error message if the data is incomplete. Setup Create a Supabase project with market_rentals and market_sales tables and
