    -   Swap transfers now support two methods for signing and tracking transactions:
        1.  Get payload/post transaction ([WalletConnect](https://d9awyx7m9zmryg2.productfruits.help/en/article/types-of-crypto-wallets-for-security-tokens))
        2.  Get payload/post payload ([Integrated wallet](https://d9awyx7m9zmryg2.productfruits.help/en/article/integrated-wallets))
-   **Direct access to testing services will no longer be available**, all testing requests must go through the API gateway URLs (`api-testing.tokeny.com/[service]`). This change is currently limited to the testing environment, with **production updates planned for 31st January**. Please ensure your integrations are updated to align with the new gateway requirements. For detailed guidance on the migration process and a complete list of changes, please refer to the article [here](https://docs.tokeny.com/docs/migration-of-urls-to-use-the-api-gateway).
