Overview of New Features in the Toncenter API

The first half of this year was dedicated to expanding the Toncenter API with powerful new features that apps and services can leverage to deliver an exceptional user experience.

— Actions API
The Actions API can detect patterns in sequences of blockchain transactions and return user-friendly data, such as “Exchange 1,000 USDt on DeDust DEX”, “Deposit TON into @stakee staking”, or “Bid in a Telegram Gift auction”.

Since its initial release, the API has undergone several updates using a convenient versioning system. With each version — v1, v2, and etc — the number of supported actions and services has continued to grow.

— Pending API
This API allows you to track blockchain operations that are still in progress. Messages sent to the blockchain appear instantly in this API, along with their processing status.

— Standardized Action IDs
Normalized extrernal message hash are now standardized, ensuring a reliable way to locate and track any sent message within the TON Blockchain. This is especially useful when monitoring pending actions.

— Streaming API (WebSockets / SSE)
The Streaming API provides real-time updates on both pending and confirmed transactions and actions.

— Emulation API
The Emulation API predicts what actions will occur before a message is sent to the blockchain, improving both user convenience and safety.

— Metadata API Enhancements
This API allows retrieval of cached token metadata, including icons and additional descriptive information.

— Traces API Enhancements
Transaction trace detection has been improved, with better recognition of related transaction series on the blockchain.

— TON DNS Support

— Get-method ID Support

Most of these features were not only introduced but also iterated on multiple times, with refinements improving their usability and accuracy.

We’re proud to equip developers with powerful new tools—and even prouder that leading TON products have already adopted them, driving a leap forward in UI and UX. More on this in the next post.
