What Adyen Platforms (BYOK) is for

Adyen Platforms (BYOK) lets an AI assistant read your own Adyen Platforms data through the Adyen Platforms API with a key you supply (Adyen API key with read-only roles for transfers and capital). Read-only: 12 tools (list_transfers, get_transfer, list_transactions, get_transaction, list_capital_grants, get_capital_grant, list_grant_disbursements, get_grant_disbursement, get_grant_account, list_grant_offers, get_grant_offer, list_dynamic_offers). The BYOK key travels with each request, is used for that one call only and is never stored, logged or cached; it is only ever sent to balanceplatform-api-test.adyen.com, balanceplatform-api-live.adyen.com. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Adyen Platforms. Adyen Platforms and its logos are trademarks of their owners and are used only to say which service the connector works with.

Ask your assistant things like:

  • "What transfers did my balance account make in January 2026?"
  • "What is the status of transfer 1VVF0D5U66PIUIVP?"
  • "Which transactions were booked on balance account BA00000000000000000000001 last month?"
  • "Show transaction EVJN42CKX2223S5N"
  • "Which capital grants does account holder AH00000000000000000000001 have?"
  • "How much is still owed on grant GR00000000000000000000001?"

BYOK key

You bring your own Adyen Platforms Adyen API key with read-only roles for transfers and capital (https://docs.adyen.com/development-resources/api-credentials/). Your assistant sends it in the X-Upstream-Key header with each request. ConnectorBay uses it for that one call only: it is never stored, logged or cached, never shown in an answer, and it is only sent to balanceplatform-api-test.adyen.com, balanceplatform-api-live.adyen.com over https, with no redirects followed. Create a key with the fewest permissions the tools need (read-only if the provider offers it), and revoke it at the provider whenever you like.

Data sources

Live from the Adyen Platforms API (balanceplatform-api-test.adyen.com, balanceplatform-api-live.adyen.com) with a BYOK key; documentation: https://docs.adyen.com/api-explorer/Transfers/4/overview. Endpoints checked against that documentation on 2026-10-16.
