Connect purchasing to your system
Grossa provides purchasing and activation APIs where service settings and account permissions allow access.
Get access in your account
Open the API section of the Telegram bot to check access, issue credentials and obtain the current documentation. Public storefront pages do not contain private API credentials.
Keep the integration on your server
Check quantities, current availability and order results. Store API keys securely on the server. Follow documented status handling and avoid repeating a paid purchase merely because a request timed out.
Track fulfillment separately
Starting an activation and completing it are different events. Handle pending orders and requests for customer information. Use the published API contract rather than scraping this catalog.
Start with the right batch.
Choose a plan, review its terms and place your order in your Grossa account. The minimum batch depends on the product.
