Request language templates
Original transport templates derived from this endpoint’s documented method, server, authentication and media type. Replace path/query/credential placeholders with authorized sandbox values. These examples print the raw status and response; they do not infer business success or retry a request. Node requires a runtime with fetch; PHP requires cURL. Generated source-based examples have not been executed against provider accounts. curl --request GET \ --url 'https://sandbox.signup.nmi.com/api/v1/subscriptions/{subscription}' \ --header 'Authorization: Bearer <access-token>' const response = await fetch("https://sandbox.signup.nmi.com/api/v1/subscriptions/{subscription}", { method: 'GET', headers: { "Authorization": "Bearer <access-token>" } }); console.log(response.status, await response.text()); from urllib.request import Request, urlopen from urllib.error import HTTPError request = Request('https://sandbox.signup.nmi.com/api/v1/subscriptions/{subscription}', method='GET', headers={'Authorization': 'Bearer <access-token>'}) try: with urlopen(request, timeout=30) as response: print(response.status, response.read().decode()) except HTTPError as error: print(error.code, error.read().decode()) require 'net/http' require 'uri' uri = URI("https://sandbox.signup.nmi.com/api/v1/subscriptions/{subscription}") request = Net::HTTP::Get.new(uri) request["Authorization"] = "Bearer <access-token>" response = Net::HTTP.start(uri.hostname, uri.port, use_ssl: uri.scheme == 'https', read_timeout: 30) { |http| http.request(request) } puts response.code puts response.body <?php $curl = curl_init('https://sandbox.signup.nmi.com/api/v1/subscriptions/{subscription}'); curl_setopt_array($curl, [ CURLOPT_CUSTOMREQUEST => 'GET', CURLOPT_RETURNTRANSFER => true, CURLOPT_TIMEOUT => 30, CURLOPT_HTTPHEADER => ['Authorization: Bearer <access-token>'] ]); $response = curl_exec($curl); if ($response === false) { throw new RuntimeException(curl_error($curl)); } echo curl_getinfo($curl, CURLINFO_HTTP_CODE), PHP_EOL, $response; curl_close($curl);

Validate the request against its selected schema before submission. Keep secrets outside browser code. Test permitted and denied account access, validation failures and interrupted responses in the sandbox. Account-management or messaging operations require the corresponding partner access and intended recipient context.
