response

HTTP/1.1 200 OK
Content-Type: application/json

{"code": "TRANSACTION_RECEIVED", "tx_id": 5678}

Response:

Parameters

• code – The response code of the request.

• tx_id – The tx_id of the request this reponse belongs to.

async get_first_unused_tx_id(request: aiohttp.web_request.Request) → aiohttp.web_response.Response

Gets the next transaction id that all of its predecessors exist in the system. If no ids exist in the system - then 0 will be returned.

While most of the time this implies the next tx_id used should be the returned value, this is not guaranteed, since while this value is returned, some new transaction may be written, rendering the returned response irrelevant.

Returns

The next consecutive tx_id, all of its predecessors exist in our system.

Return type

int
