StrictSendPathsRequestBuilder extends RequestBuilder
in package

Builds requests for the strict send paths endpoint in Horizon

This class provides methods to find payment paths where the source amount and asset are fixed (strict send). It returns possible paths showing what destination assets and amounts will be received when sending the exact source amount.

Query Methods:

  • forSourceAccount(): Filter paths by source account
  • forSourceAsset(): Set the asset to be sent (required)
  • forSourceAmount(): Set the exact amount to be sent (required)
  • forDestinationAccount(): Filter paths by destination account
  • forDestinationAssets(): Filter paths by possible destination assets

This is the recommended method for finding payment paths when you know the exact amount to send and want to discover what the recipient will receive.

Usage Examples:

// Find paths when sending exactly 50 XLM $sourceAsset = Asset::native(); $paths = $sdk->strictSendPaths() ->forSourceAccount("GDAT5...") ->forSourceAsset($sourceAsset) ->forSourceAmount("50") ->forDestinationAccount("GBBD...") ->execute();

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

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

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 —

This instance for method chaining
