<MethodEndpoint method={"get"} path={"/v2/config/digital-wallet/openid/sdjwt/transaction-data/{transactionDataId}"}></MethodEndpoint>



Reads one transaction data record by its `transactionDataId`.

The digital wallet of the organisation must be deployed. If it is not, the server answers with HTTP 400.

Unique identifier of the sandbox organisation to use for this request. When you send this header, the service runs the operation in the context of the named sandbox organisation, that is, against the wallet of that sandbox organisation and not against the main wallet of the organisation. Leave the header out to use the main wallet.\n\nThe service reads this header only when you authenticate with a bearer access token. When you authenticate with an API key, the service takes the sandbox organisation from the API key and ignores this header. To run an API-key call in a sandbox organisation, bind the key to the sandbox organisation with `PUT /v2/config/admin/apikey/{apiKeyId}/sandbox-org` instead.\n\n`X-SubwalletId` is the deprecated name of this header. The service continues to accept it, but `X-SandboxOrgId` wins if you send both headers.\n\nThe sandbox organisation must exist, must belong to your organisation and must be deployed. An unknown identifier, an identifier of a sandbox organisation that is not deployed, and an identifier that belongs to a different organisation all make the call fail with HTTP 400.","in":"header","name":"X-SandboxOrgId","required":false,"schema":{"type":"string"},"example":"6889e1a4c5b2f30001a3d710"}}></ParamsItem></ul></div></details><div><div><ApiTabs label={undefined} id={undefined}><TabItem label={"200"} value={"200"}><div>
