Sep24PostRequestBuilder extends RequestBuilder

Builder for SEP-24 POST requests to interactive deposit and withdrawal endpoints

This builder constructs and executes POST requests to SEP-24 interactive endpoints, handling multipart form data submission including both field data and file uploads. It is used internally by the InteractiveService to initiate deposit and withdrawal flows that require user interaction through a web interface.

The builder handles:

  • JWT authentication token injection
  • Multipart form encoding for fields and files
  • Response parsing into SEP24InteractiveResponse

Methods

__construct()

Constructor.

public __construct(Client $httpClient, string $serviceAddress, string $endpoint, string $jwtToken, array<string|int, mixed> $fields[, array<string|int, mixed>|null $files = null ]) : mixed
Parameters
$httpClient : Client

the client to be used for the request.

$serviceAddress : string

the server address of the sep-24 service (e.g. from sep-01).

$endpoint : string

the endpoint to be called. e.g. 'transactions/withdraw/interactive'

$jwtToken : string

the jwt token obtained from sep-10 authentication.

$fields : array<string|int, mixed>

the data fields to be added to the request.

$files : array<string|int, mixed>|null = null

the files to be added to the request.

buildUrl()

Builds the url for the request.

public buildUrl() : string
Return values
string

the constructed url.

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

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
