SubmitAsyncTransactionRequestBuilder extends RequestBuilder
in package

Builds requests for submitting transactions asynchronously to Horizon

This class provides methods to submit signed transactions to the Stellar network asynchronously. Unlike synchronous submission, async submission returns immediately without waiting for the transaction to be included in a ledger.

Async submission is useful for high-throughput scenarios where you don't need to wait for transaction confirmation. The response indicates whether the transaction was accepted for processing, but not whether it succeeded in the ledger.

Usage Examples:

// Submit a signed transaction asynchronously $response = $sdk->submitAsyncTransaction() ->setTransaction($signedTransaction) ->execute();

// Check async submission status if ($response->getTxStatus() === "PENDING") { echo "Transaction submitted: " . $response->getHash() . PHP_EOL; // Poll transaction status separately }

Methods

__construct()

Constructor

public __construct(Client $httpClient) : mixed
Parameters
$httpClient : Client

The HTTP client used for making requests to Horizon

buildUrl()

Builds the complete request URL with all segments and query parameters

public buildUrl() : string

Combines the URL path segments with query parameters to create the final request URL string that will be sent to Horizon.

Return values
string —

The constructed URL with query parameters

cursor()

Sets <code>cursor</code> parameter on the request.

public cursor(string $cursor) : RequestBuilder

A cursor is a value that points to a specific location in a collection of resources. The cursor attribute itself is an opaque value meaning that users should not try to parse it.

Parameters
$cursor : string

executeRequest()

Executes an HTTP request to Horizon and returns a parsed response object

public executeRequest(string $url, string $requestType[, string|null $requestMethod = "GET" ]) : Response

This method sends the HTTP request to the Horizon server, handles errors, and parses the JSON response into the appropriate response type.

Parameters
$url : string

The complete request URL to fetch

$requestType : string

The expected response type for parsing

$requestMethod : string|null = "GET"

The HTTP method to use (default: "GET")

Tags
throws
HorizonRequestException

If the request fails or response cannot be parsed

Return values
Response —

The parsed response object of the specified type

getAndStream()

Streams Server-Sent Events from Horizon to a callback function

public getAndStream(string $relativeUrl, callable $callback[, bool $retryOnServerException = true ]) : void

This method establishes a persistent connection to Horizon's streaming endpoints using Server-Sent Events (SSE). It processes each event and passes the parsed data to the provided callback function. The stream automatically reconnects on server exceptions if retryOnServerException is true.

Horizon streaming uses SSE to push real-time updates. The stream sends:

  • "hello" message on connection
  • "byebye" message on disconnection
  • JSON data objects for actual events
Parameters
$relativeUrl : string

The relative URL to stream from

$callback : callable

Function to receive parsed event data

$retryOnServerException : bool = true

If true, automatically retry on server errors (default: true)

Tags
throws
GuzzleException

If a network error occurs and retryOnServerException is false

Return values
void —

This method runs indefinitely until interrupted

limit()

Sets <code>limit</code> parameter on the request.

public limit(int $number) : RequestBuilder

It defines maximum number of records to return. For range and default values check documentation of the endpoint requested.

Parameters
$number : int

Maximum number of records to return

Return values
RequestBuilder

setTransaction()

Use this method to set the transaction object to be submitted.

public setTransaction(AbstractTransaction $transaction) : $this

It will be used to build a transaction envelope xdr base64 string that will be submitted to the network.

Parameters
$transaction : AbstractTransaction

Transaction to be submitted to the network.

Return values
$this

setTransactionEnvelopeXdrBase64()

Use this method to set the base 64 encoded transaction envelope to be submitted to the network.

public setTransactionEnvelopeXdrBase64(string $txEnvelopeXdrBase64) : $this
Parameters
$txEnvelopeXdrBase64 : string

The base 64 encoded transaction envelope to be submitted to the network.

Return values
$this

setSegments()

Sets the URL path segments for this request

protected setSegments(string ...$segments) : RequestBuilder

This method constructs the URL path by combining multiple segments. Can only be called once per request builder instance.

Parameters
$segments : string

Variable number of URL path segments

Tags
throws
RuntimeException

If segments have already been set

Return values
RequestBuilder —
