For the fastest solution integrating blinks, consider using our UI Component libraries, available for both web and mobile.Using these libraries can reduce your integration time by up to 99%.
Headless blink integrations are perfect for developers who want pure data fetching without UI constraints. You get direct API access and can build your own interfaces and implementations from scratch. Headless integration is also ideal for integration into more complex systems, such as AI agents. In the examples below, we’ll walk you through the basics and all available endpoints, helping you determine which endpoint best suits your use case. Before using our APIs, we recommend requesting a client key. A client key is a unique identifier used to register your blink in the terminal. This registration gives you access to:
  • High-performance caching solutions
  • Customized metadata
  • Individualized status messages (onSuccess, onFailure, …)
  • Analytics
These features enable you to build a truly unique experience for your users. To get your client key, please sign up for our terminal. In our examples and API documentation, the client key may be referred to as YOUR_SECRET_TOKEN.
The X-Blink-Client-Key header is optional. You can use our API endpoints without a client key, but you’ll miss out on the features mentioned above.
Dialect’s APIs provide three endpoints for fetching blink data: Blink, BlinkPreview, and BlinkDataTable. Blink UI Components The BlinkPreview allows you to display a preview version of the blink with its own title, description, and image. It can be used for marketing purposes or in cases where you only want to render a preview without needing the full blink data. The Blink endpoint contains all blink-related data, including its actions and the BlinkPreview. Use this API when you plan to interact with the blink. It is highly recommended to use the Dialect API when fetching a blink to benefit from all the additional features our SaaS platform offers. In the following example, we’ll use the stake blink from Jito to guide you through the different API requests.

​
GET Requests

The GET endpoint returns a JSON object that renders the blink or provides blink-relevant data, such as the BlinkDataTable. A Blink contains the complete, interactive data structure. It includes all necessary information to display and interact with a Blink, including its current state, possible actions, and related data. This is the primary structure you’ll work with when implementing blink functionality in your application. Image of a Blink incl. Blink Data Table and Extended Description There are no strict requirements for image dimensions, but we recommend using either 16:9 or 1:1 aspect ratios. 
# CURL example to fetch a blink
# Note: The X-Blink-Client-Key header is optional but recommended

curl 'https://api.dial.to/v1/blink?apiUrl=https%3A%2F%2Fjito.dial.to%2Fstake' \
  --header 'X-Blink-Client-Key: YOUR_SECRET_TOKEN'
The above command will return a JSON object that can be used to render the blink.

Fetching a BlinkDataTable

In addition to the Blink and BlinkPreview endpoints, we offer a BlinkDataTable endpoint. This can be used to highlight important information for your users, such as APY or balances. Because BlinkDataTables are often compute-intensive, they have their own endpoint. This separation allows you to fetch them only when needed. Image of a Blink Data Table

​
Fetching a BlinkPreview

BlinkPreview is a small, static set of data used to display relevant information about the blink. Consider it an opportunity to use marketing language and render a preview instead of the full blink - useful for lists or websites that don’t yet unfurl blinks. It is recommended to use a separate 16:9 image for this preview. Image of a Preview Blink

​
POST requests

Once a user clicks on a button, the blink will send a POST request to your backend. This request always contains the wallet address (account) of the user. Additional data can be sent via the URL, e.g., by using URL parameters. Example URL for POST: https://jito.dial.to/stake/percentage/25 In this blink, we use our example from the Jito staking blink again. Please note that the URL has changed from /stake (GET endpoint) to /stake/percentage (POST endpoint). The number 25 indicates that 25% of the user’s SOL balance will be staked. There are no specific requirements for the design of your link structure or endpoints. Most blinks use the same endpoint for their GET and POST requests and utilize URL parameters to add extra values. 
# CURL example of a blink POST request
# Note: The X-Blink-Client-Key header is optional but recommended

curl 'https://api.dial.to/v1/blink?apiUrl=https%3A%2F%2Fjito.dial.to%2Fstake%2Fpercentage%2F25' \
  --request POST \
  --header 'Content-Type: application/json' \
  --header 'X-Blink-Client-Key: YOUR_SECRET_TOKEN' \
  --data '{
  "type": "transaction",
  "account": "YOUR_WALLET_ADDRESS"
}'
If everything is correct, the blink provider will send a transaction to the frontend that can be signed by the user. Creating a ready-to-sign transaction in the backend and sending this transaction to the frontend is one of the superpowers of building with blinks. This approach gives blink builders the power to implement their services in the way they know works best, thereby:
  • Reducing the chances of incorrect implementations
  • Providing a single point of maintenance
  • Ensuring full control over the blink
Blink clients who want to integrate new services for their users can simply fetch a blink, eliminating the need for client-side SDKs or complex implementation scenarios. Blinks are also the preferred way for teams who want to integrate their services into AI agent kits. The blink provider from the example above will return the following JSON:

Multi-Step Blinks: Action Chaining

Action chaining example flow Action Chaining allows you to create complex workflows by connecting multiple blink actions in a sequential order. Instead of handling single, isolated actions, you can orchestrate a series of interconnected steps to create more complex user experiences. Our SDKs are the recommended way to implement action chaining as they handle the complexity for you.

​
Input types

Blinks can be more than just one-click button actions. In fact, they can become really powerful when you add multiple inputs. If you look at our Standard Blinks Library (SBL), you will find many blinks that feature radio buttons, dropdown menus, checkboxes, and much more. This allows you to build full-fledged forms or even games that run entirely on blinks. Blink Forms If you want to learn more about the input types that you can use for your blink, check out our forms section.

​
Wallets and Apps

As mentioned in the POST section, blinks offer a fast and secure way to implement new services into your app, and implementation becomes even easier when using our UI component kits. Many wallets have already chosen to use blinks instead of implementing each service for their users themselves. Blink integration in apps and wallets The blink UI component kits are available for React and React Native. Using our terminal, you can remotely manage your app’s blinks: add new ones, change their order, and track their performance—all without deploying a new version of your app. The terminal is also home to our Standard Blinks Library (SBL), the fastest way to discover all available blinks. From swapping and lending to staking and more, all blinks can be found there. They can be customized and integrated into your app with no-code solutions in just a few clicks. The blink technology is chain-agnostic. While it originated on Solana, blinks are now fully EVM-compatible. All you need to do is set the correct CORS headers. 
// CORS headers example for multiple chains

import { ACTIONS_CORS_HEADERS } from "@solana/actions";

// CORS for Solana Devnet
const solanaDevnetHeaders = {
  ...ACTIONS_CORS_HEADERS,
  "x-blockchain-ids": "solana:EtWTRABZaYq6iMfeYKouRu166VU2xqa1", // CAIP2 SOL devnet
  "x-action-version": "2.4",
};

// CORS for Monad Testnet
const monadHeaders = {
  ...ACTIONS_CORS_HEADERS,
  "x-blockchain-ids": "eip155:10143", // CAIP2 MON testnet
  "x-action-version": "2.4",
};
