The populated fields vary based on the transaction type. For **CRYPTO\_DEPOSIT** and **CRYPTO\_WITHDRAWAL** transaction types, you must use [Fetch Transaction Details V2](/api-reference/transactions/fetch-transaction-details-v2). We also recommend migrating all transaction detail lookups to V2, as V1 will be deprecated soon. ## OpenAPI ````yaml GET /v1/transactions/{transaction_id} openapi: 3.1.0 info: title: Fin.com API version: 1.0.0 description: A simple API specification servers: - url: https://sandbox.api.fin.com description: Sandbox server - url: https://api.fin.com description: Production server security: [] tags: - name: Authentication description: A modified OAuth 2.0 Client Credential Flow - name: Customers description: Customer management and document upload operations - name: Balances description: Retrieve wallet balance information - name: Catalogue description: | A set of endpoints to retrieve contextual data to assemble requests to fin.com's API - name: Beneficiaries description: Manage beneficiary accounts for payments and transfers - name: Transactions description: Transaction history and management for beneficiaries - name: Virtual Accounts description: Create and manage virtual accounts for USD to USDC conversions - name: Fees & FX Rates description: Retrieve fees and foreign exchange rates paths: /v1/transactions/{transaction_id}: get: tags: - Transactions summary: Fetch Transaction Details V1 description: >- Returns full details for a transaction by ID, including status, amounts, fees, and settlement data.
