# Sign Transaction In this section, you will find comprehensive guides to implementing transaction signing using our SDK and API: * [**Sign Transaction SDK**](/wallet-operations/passkeys-signer/sign-transaction/sign-transaction-sdk.md): Get started with our SDK to integrate message signing into your application. The SDK flow abstracts away most interactions, making it the easiest way to get started * [**Sign Transaction API**](/wallet-operations/passkeys-signer/sign-transaction/sign-transaction-api.md): If you're not using TypeScript or prefer to use an API, you can directly make HTTP requests to sign messages. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.0xpass.io/wallet-operations/passkeys-signer/sign-transaction.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
