Guide**\n\n## What this workflow does\n\nA Telegram bot to manage your PPOB business:\n\n* Check **deposit balance**\n* Browse **product price list**\n* Start **prepaid topups**\n* **Check** and **pay** postpaid bills\n* Show **transaction history**\n (Inline keyboards + message/callback handling are included.)\n\n## Prerequisites\n\n* n8n up and running (self-hosted or desktop).\n* A **Telegram Bot Token** (create via @BotFather).\n* A **Digiflazz** account with **Username** and **API Key**.\n\n## Environment variables (set in n8n)\n\n* `DIGIFLAZZ_USERNAME` = your Digiflazz username\n* `DIGIFLAZZ_API_KEY` = your Digiflazz API key\n\n> n8n \u2192 Settings (or container env) \u2192 add the vars \u2192 restart if needed.\n\n## Install steps\n\n1. **Import** the workflow JSON into n8n.\n2. Open **Telegram Trigger** \u2192 select your **Telegram credentials**.\n\n * Updates listened: `message` & `callback_query` (already configured).\n3. **Activate** the workflow.\n4. On Telegram, DM your bot and send `/start`.\n\n## How to use (commands & buttons)\n\n* `/start` \u2192 Welcome & quick actions.\n* `/menu` \u2192 Main menu:\n\n * **\ud83d\udcb0 Check Balance** \u2192 calls `cek-saldo` and formats status with traffic-light icons (Red < Rp100k, Yellow < Rp500k, Green \u2265 Rp500k). Timestamp uses **Asia/Jakarta**.\n * **\ud83d\udecd\ufe0f Product List** \u2192 calls `price-list`, groups by category, renders inline buttons.\n * **\ud83d\udcb3 Prepaid Topup** \u2192 choose product type (Pulsa/Data/PLN/Game/E-Wallet/TV). Bot prompts for the required number/ID.\n * **\ud83c\udff7\ufe0f Check Bills** / **\ud83d\udcb0 Pay Bills** \u2192 choose bill type, bot prompts for customer ID; workflow prepares inquiry/payment call.\n * **\ud83d\udcb8 Deposit** \u2192 shows admin contact & deposit tips.\n * **\ud83d\udcc8 History** \u2192 scaffold provided for last 7 days.\n\n## Under the hood (API & signing)\n\n* **MD5 signature** is built in Code nodes using Node\u2019s `crypto`, e.g.\n `md5(username + apiKey + 'pricelist' | 'depo' | 'history')`.\n* HTTP nodes hit Digiflazz endpoints: `cek-saldo`, `price-list`, `transaction`, `inquiry`.\n* Switch router maps `/start`, `/menu`, and inline `callback_data` to the right branch.\n\n## Customize\n\n* Update admin contacts/text in **Telegram** nodes to your details.\n* Map additional product/bill flows and payload fields as needed.\n* For production, replace the simple in-memory session in Code nodes with **Redis/DB**.\n\n## Notes & gaps\n\n* **Transaction History** and **category-level product clicks** are scaffolded; add the missing HTTP calls/routers if you want full results in chat.\n* Keep your API key in env vars\u2014**never** hard-code in nodes.\n\n**Quick test**\n\n1. Send `/start` \u2192 tap **\ud83d\udcb0 Check Balance**.\n2. Tap **\ud83d\udecd\ufe0f Product List** \u2192 see grouped categories.\n3.
