Payment system token​

To receive payments from clients, you need to obtain a unique token of the payment system and specify it in the tag parameters. Create a bot in Telegram before obtaining a token. Follow the steps described in the Telegram as an inbound channel article and return to this one.

  1. Open Telegram and enter BotFather in the search bar.
  2. Send the /mybots command to BotFather.
  3. Choose your bot and select Payments.
  4. Choose a payment system from the list.
  5. Choose one of the payment methods:
    • Test for testing the payment system.
    • Live for setting up a real payment system integration.
  6. You will be redirected to a chatbot for the selected payment system. Start the chatbot.
  7. Follow all the steps the chatbot asks for.
  8. Return to the chat with BotFather.
  9. In the last message from BotFather, you will see a list of connected payment systems and tokens for each of them. Copy the token for the selected payment system.
  10. Paste the token in the providerToken parameter.

Price limits​

Telegram sets limits on the minimum and maximum entered amount for each currency. The minimum and maximum amount for each of the currencies roughly correspond to the limit of 1­­–10,000 USD. For each currency except USD, these limits depend on exchange rates and may change over time.

You can find approximate values of the minimum and maximum amount for each supported currency in the Telegram documentation.
