Server tool list (20)
Raw names from tools/list. Only developers need these.
| get_docs | Read a TgPay Merchant API integration doc. START HERE before integrating: topics quickstart, invoices, subscriptions, transfers-checks, webhooks, errors. |
| connect | Start token issuance WITHOUT the Mini App UI: creates a merchant-app request and returns a t.me approve link plus a poll_secret. Show the link to the human — they approve with one button in the @tgpaycryptobot bot — then call connect_status with the poll_secret. Use only when no API token is configured yet. |
| connect_status | Poll a connect request. Returns pending | denied | expired, or — once approved — the app id and the API TOKEN (returned exactly once: save it to the project's .env immediately, never print it in logs). The token is SCOPED (read, invoices, subscriptions, webhooks) — it cannot move money out of the app; transfers/refunds/checks need the primary token the human holds in the Mini App. Poll every 3-5 seconds while pending. |
| getMe | Verify the token: app id, name, webhook config, token scopes. |
| getBalance | Merchant app balance per asset (available + onhold). |
| getCurrencies | Supported crypto assets (code/name/decimals) and fiats. |
| getExchangeRates | Current asset↔fiat display rates. |
| getStats | App volume/count stats for a period. |
| getInvoices | List invoices (newest first). |
| getChecks | List checks. |
| getTransfers | List app→user transfers. |
| getSubscriptionPlans | List subscription plans. |
| getSubscriptions | List subscriptions (subscribers). |
| createInvoice | Create a one-off payment invoice; the payer opens result.mini_app_invoice_url. See the invoices doc. |
| deleteInvoice | Delete an unpaid invoice. |
| deleteCheck | Delete an unclaimed check (refunds the hold). |
| createSubscriptionPlan | Create an IMMUTABLE recurring-billing plan; send payers to result.mini_app_subscribe_url. See the subscriptions doc. |
| archiveSubscriptionPlan | Stop new signups for a plan (live subscriptions keep renewing). |
| cancelSubscription | Stop future charges for one subscription (paid time runs out). |
| updateApp | Update app name / webhook_url (https) / webhook_events opt-in list. Needs the 'webhooks' scope (the connect-issued token has it) or the primary token. See the webhooks doc for the event types and signature verification. |
