Mercury Bank + Slack Integration\n\nThis project integrates Mercury Bank's API with Slack, allowing you to:\n- Check account balances\n- View recent transactions\n- Get notifications for important account events\n- Search and filter transactions\n- **Receive automatic notifications for new transactions**\n\n## Project Structure\n\n- `/backend/` - Server-side code for handling API requests\n - `index.ts` - Main HTTP entry point\n - `mercury.ts` - Mercury API client\n - `slack.ts` - Slack message formatting and command handling\n - `notifications.ts` - Transaction notification system\n - `cron.ts` - Scheduled job to check for new transactions\n- `/shared/` - Shared types and utilities\n - `types.ts` - TypeScript interfaces for Mercury and Slack data\n\n## Setup Requirements\n\n1. Mercury API credentials (stored as environment variables)\n2. Slack App with slash commands configured\n3. Slack Incoming Webhook URL for transaction notifications\n4. Webhook URL from this Val pointing to your Slack app\n\n## Usage\n\nOnce configured, you can use the following slash commands in Slack:\n- `/mercury balance` - Check your account balances\n- `/mercury transactions [count]` - View recent transactions\n- `/mercury search [query]` - Search transactions\n\n## Transaction Notifications\n\nThe integration supports two methods for transaction notifications:\n\n1. **Webhook Method** (if Mercury supports webhooks):\n - Receives real-time notifications from Mercury when transactions occur\n - Posts formatted transaction details to your Slack channel immediately\n\n2. **Polling Method** (fallback option):\n - Regularly checks for new transactions via the Mercury API\n - Compares with previously seen transactions to identify new ones\n - Posts new transaction details to your Slack channel\n\n## Security Notes\n\n- All API credentials are stored as environment variables\n- No sensitive data is logged or stored",[],[235],{"_102":244,"_95":245,"_151":246,"_153":-5,"_154":136,"_155":247,"_157":158,"_104":248,"_99":173,"_160":239,"_162":249,"_163":22,"_164":-5,"_165":250,"_98":251},"d40e4a4c-30eb-11f0-87bf-569c3dd06744","SETUP.md","8b7a1158-30eb-11f0-afbe-569c3dd06744",14,["D",1747244988152],"# Setup Guide for Mercury Bank + Slack Integration\n\nFollow these steps to set up your Mercury Bank and Slack integration:\n\n## 1. Mercury API Setup\n\n1. Log in to your Mercury account at https://mercury.com\n2. Navigate to Developer Settings\n3. Create a new API key with the following permissions:\n - `accounts:read` - To read account information\n - `transactions:read` - To read transaction data\n4. Copy your API key for the next step\n\n### Mercury Webhook Setup (If Available)\n\nIf Mercury supports webhooks for transaction notifications:\n\n1. In your Mercury developer settings, look for \"Webhooks\" or \"Event Subscriptions\"\n2. Register a new webhook with the following details:\n - URL: Your Val Town HTTP endpoint URL (same as for Slack commands)\n - Events: Subscribe to `transaction.created` or similar events\n - Authentication: Follow Mercury's instructions for webhook authentication\n\n## 2. Val Town Environment Variables\n\nSet up the following environment variables in Val Town:\n\n1. `MERCURY_API_KEY` - Your Mercury API key from step 1\n2. `SLACK_SIGNING_SECRET` - You'll get this in step 3\n3. `SLACK_WEBHOOK_URL` - You'll get this in step 3\n\n## 3. Slack App Setup\n\n1. Go to https://api.slack.com/apps and click \"Create New App\"\n2. Choose \"From scratch\" and give your app a name (e.g., \"Mercury Bank\")\n3. Select the workspace where you want to install the app\n4. Under \"Basic Information\", note your \"Signing Secret\" and add it to Val Town as `SLACK_SIGNING_SECRET`\n5. Under \"Slash Commands\", create a new command:\n - Command: `/mercury`\n - Request URL: Your Val Town HTTP endpoint URL (copy from the Val Town UI)\n - Short Description: \"Interact with your Mercury bank account\"\n - Usage Hint: \"[balance|transactions|search] [args]\"\n6. Under \"Incoming Webhooks\", activate incoming webhooks\n - Click \"Add New Webhook to Workspace\"\n - Select the channel where you want transaction notifications to appear\n - Copy the Webhook URL and add it to Val Town as `SLACK_WEBHOOK_URL`\n7. Under \"OAuth & Permissions\", add the following scopes:\n - `commands` - To create slash commands\n - `chat:write` - To post messages in channels\n - `incoming-webhook` - To post notifications via webhook\n8. Install the app to your workspace\n\n## 4. Cron Job Configuration\n\nThe integration includes a cron job that checks for new transactions regularly:\n\n1. In Val Town, locate the `cron.ts` file\n2. Click on the \"Schedule\" button to set up the cron schedule\n3. Recommended: Set it to run every 15 minutes (*/15 * * * *)\n\n## 5. Testing the Integration\n\n1. In Slack, try the command `/mercury help` to see available commands\n2. Try `/mercury balance` to see your account balances\n3. Try `/mercury transactions 5` to see your 5 most recent transactions\n4. For transaction notifications:\n - If using webhooks: Make a test transaction in Mercury\n - If using polling: Wait for the cron job to run, or trigger it manually\n\n## Troubleshooting\n\n- If you see \"An unexpected error occurred\", check your Val Town logs for details\n- Ensure your Mercury API key has the correct permissions\n- Verify that your Slack app is properly configured with the correct URL\n- For transaction notifications, check that the `SLACK_WEBHOOK_URL` is correctly set\n\n## Security Considerations\n\n- Your Mercury API key has access to sensitive financial data. Keep it secure.\n- Consider implementing additional authentication if multiple users will access this integration.\n- For production use, implement proper request signature verification from Slack and Mercury.",[],[245],"files",[148,167,178,188,198,207,217,224,233,243],"counts",{"_256":32,"_257":173,"_258":32,"_259":221},"pulls","branches","forks","envVars","contents",[262,265,268,271],{"_102":149,"_95":150,"_151":152,"_153":-5,"_154":136,"_155":156,"_157":158,"_104":263,"_99":32,"_160":161,"_162":-5,"_163":22,"_164":-5,"_98":264},["D",1747244814390],[150],{"_102":218,"_95":219,"_151":220,"_153":-5,"_154":136,"_155":221,"_157":158,"_104":266,"_99":32,"_160":161,"_162":-5,"_163":22,"_164":-5,"_98":267},["D",1747244801116],[219],{"_102":234,"_95":235,"_151":236,"_153":-5,"_154":136,"_155":237,"_157":158,"_104":269,"_99":193,"_160":239,"_162":240,"_163":22,"_164":-5,"_98":270},["D",1747245000784],[235],{"_102":244,"_95":245,"_151":246,"_153":-5,"_154":136,"_155":247,"_157":158,"_104":272,"_99":173,"_160":239,"_162":249,"_163":22,"_164":-5,"_98":273},["D",1747244988152],[245],"upstreamProject","upstreamBranch","emptyEnvVars","isNew","flags",[],"routes/_app.x.$handle.$name.environment-variables",{"_93":94,"_95":96,"_100":282,"_259":287},{"_102":103,"_95":96,"_104":283,"_106":-5,"_107":22,"_108":109,"_110":-5,"_111":-5,"_14":112,"_113":-5,"_114":22,"_115":-5,"_116":32,"_16":117,"_118":119,"_120":119,"_121":122,"_123":122,"_124":122,"_125":119,"_126":119,"_23":284,"_130":285,"_133":286,"_145":22},["D",1747244711627],{"_93":94,"_128":129},{"_93":94,"_132":129},{"_99":135,"_95":43,"_102":136,"_137":103,"_138":-5,"_139":-5,"_140":-5,"_141":-5,"_142":-5,"_143":96,"_144":94},[288,294,297],{"_289":290,"_104":291,"_292":-5,"_110":72,"_293":22},"key","SLACK_WEBHOOK_URL",["D",1747245754237],"updatedAt","isEmpty",{"_289":295,"_104":296,"_292":-5,"_110":72,"_293":22},"SLACK_SIGNING_SECRET",["D",1747245702318],{"_289":298,"_104":299,"_292":-5,"_110":72,"_293":22},"MERCURY_API_KEY",["D",1747245119707],"actionData","errors"]
