Hi. What sort of functionality do you need? The answer will depend on the level of flexibility you need. Creating subscriptions in Paypal is quite simple, but if you need your system to programmatically alter them, that's a major challenge. On our website, https://calltaker.co, we have implemented 4 different subscription plans, where the customer chooses the plan they want, and then the customer's subscription gets created by the system automatically, with the actual monthly fee dependent on the number of registered users they have (i.e., "per seat" billing). The only action the customer needs to do is to log into Paypal and authorise the subscription. ... View more

Has anyone been able to get quantity updating on quantity-based subscriptions working with PHP? I've spent months trying to get it working. I've tried the raw CURL code, as per the developer docs and returned "PAYMENT_IN_PROGRESS" error. When using the PHP libraries, I get a 204 (no content) response and the subscription is not changed. CURL code: curl -v -X POST https://api-m.paypal.com/v1/billing/subscriptions/I-4PAEKHKDNA81/revise -H "Content-Type: application/json" -H "Authorization: Basic base64_encode($paypal_client_id.':'.$paypal_secret)" -d '{"quantity":"5"}'  (the base64 stuff is just showing how I used PHP to create a base64 version of client_id:client_secret for inserting into the CURL command)   PHP code:  <?php namespace PayPal\Api; require '/opt/bitnami/php/bin/vendor/autoload.php'; use PayPalCheckoutSdk\Orders\OrdersPatchRequest; use PayPalCheckoutSdk\Orders\OrdersGetRequest; use PayPalCheckoutSdk\Orders\OrdersCreateRequest; use PayPalCheckoutSdk\Core\PayPalHttpClient; use PayPalCheckoutSdk\Core\ProductionEnvironment; include('globals.php'); // defines Paypal client_id, client_secret, etc. $subscrID ='I-YT07M8NCEMRN'; // hard coded for test ini_set('error_reporting', E_ALL); // or error_reporting(E_ALL); ini_set('display_errors', '1'); ini_set('display_startup_errors', '1'); $environment=new ProductionEnvironment($paypal_client_id, $paypal_secret); $client = new PayPalHttpClient($environment); $request = new OrdersCreateRequest(); $request->prefer("return=representation"); $request->body =[ "intent" => "CAPTURE", "purchase_units" => [[ "reference_id" => $subscrID, "amount" => [ "value" => "1.77", "currency_code" => "USD" ] ]], "redirect_urls" => [ "cancel_url" => "https://calltaker.co/cancel", "return_url" => "https://calltaker.co/return" ] ]; $createdOrder = $client->execute($request); $request2 = new OrdersPatchRequest($createdOrder->result->id); $request2->body = [ 0=>[ "op" => "add", "path" => "/purchase_units/@reference_id=='$subscrID'/description", "value" => "3 user license" ], 1=>[ "op" => "replace", "path" => "/purchase_units/@reference_id=='$subscrID'/amount", "resource"=>[ "quantity"=>"3" ], "value" => [ "currency_code" => "USD", "value" => "1.56", "quantity" => "3" ] ] ]; try { // Call API with your client and get a response for your call $response2 = $client->execute($request2); // If call returns body in response, you can get the deserialized version from the result attribute of the response print_r($response2); }catch (HttpException $ex) { echo $ex->statusCode; print_r($ex->getMessage()); } $space4='&nbsp; &nbsp; &nbsp; &nbsp; '; foreach($response2 as $key=>$value) { print "$key = "; if (is_array($value)) { print "(array):<BR>"; foreach($value as $key2=>$value2) { print $space4.$key2."="; if (is_array($value2)) { print "(array):<BR>"; foreach($value2 as $key3=>$value3) print $space4.$space4."$key3=$value3<BR>"; } else print "$value2<BR>"; } } else print "$value<BR>"; } ?> ...

Anyone have a resolution? It's now July 2021, 2 years since this thread was opened, and I'm getting the same error. At the moment I cant use Paypal for my business because modifying the quantity of a quantity-based subscription when the customer changes their quantity, doesnt work in Live. Never been able to get it working in Test because the subscription details pages of the sandbox have never worked, so I am testing in live. If I cant resolve this then I'll have to look for an alternative method of billing subscription customers. I have used raw CURL commands, as per the developer docs, and have also used the php Paypal libraries (code below). The PHP code returns nothing, just a 204 status (no content)   namespace PayPal\Api; require '/opt/bitnami/php/bin/vendor/autoload.php'; use PayPal\Common\PayPalResourceModel; use PayPal\Validation\ArgumentValidator; use PayPal\Api\WebhookList; use PayPal\Rest\ApiContext; use PayPal\Validation\UrlValidator; use PayPalCheckoutSdk\Core\PayPalHttpClient; use PayPalCheckoutSdk\Core\PayPalEnvironment; use PayPalCheckoutSdk\Core\ProductionEnvironment; ...
