php - Stripe invalid request - using a token more than once -


code: 

stripe::setapikey($stripe_secret_key); stripe::setapiversion('2017-02-14');    // either create new customer object or retrieve existing customer object  $db->query(" select stripecustomertoken stripe_ids upper(useremail) = upper(:email) "); $db->bind(':email', $user_email); $db->execute(); $customer_token = $db->fetchsinglecolumn();  if(!$customer_token) {     $customer = stripe_customer::create(         [             'card' => $stripe_card_token,             'description' => $user_email,             'email'=>$user_email         ],         $stripe_access_token     );      $customer_token = $customer->id;      $db->query(" insert stripe_ids (useremail, stripecustomertoken) values (:e, :custid) ");     $db->bind(':e', $user_email);     $db->bind(':custid', $customer_token);     $db->execute(); }  if(!$customer_token)     throw new exception('no stripe customer token detected. payment not processed.');  $customer = stripe_customer::retrieve($customer_token);    // using token id, retrieve full token object , retrieve fingerprint `card.fingerprint` attribute  $current_card = stripe_token::retrieve($stripe_card_token); $current_card_fingerprint = $current_card->card->fingerprint; $current_card_id = $current_card->card->id;    // iterate through list of customer's saved sources , check if has same value `fingerprint`  $source_exists = false; foreach($customer->sources->data $i => $fingerprint) {     if($current_card_fingerprint === $fingerprint)         $source_exists = true; }    // if not, add card customer object  if(!$source_exists)     $customer->sources->create(['source' => $stripe_card_token]);  $customer->default_source = $current_card_id; $customer->save();    // create charge using customer id , card id  $charge = [     'customer' => $customer->id,     'source' => $current_card_id,     'amount' => $total_gross_received_cents,     'currency' => 'eur',     'description' => $transaction_description_str,     'application_fee' => $databiz_fee ];  $charge_obj = stripe_charge::create($charge, $stripe_access_token);  if(empty($charge_obj))     throw new exception('no stripe charge object detected. payment not processed.');  $charge_token = $charge_obj->id;

issue:

each time customer uses application, must enter cc details. therefore want to:

  1. create customer, if not exist
  2. check if have current card source and, if not, add source
  3. charge used card

i running trouble whereby returning customer's default card not being updated used card (resulting in funds coming default), added card id charge object, , saved current card customer's default.

the issue that, on live transaction, getting invalidrequest exception - cannot use token more once.

can point out me going wrong?

the token you're providing when adding card customer (with $customer->sources->create(...)) has been consumed api request. should check integration ensure $stripe_card_token contains "fresh" token created checkout or elements.

a few other things noticed:

  • you're using connect direct charges. means customer objects must exist on connected account, not on platform's account. when retrieve customer, don't specify connected account's api key, request issued on platform's account , fail (since customer id doesn't exist on platform's account)

  • you're using old version (1.x) of stripe's php library. should consider upgrading more recent version. require updating code new syntax (stripe_class -> \stripe\class)

  • when looking if card exists on customer, iterate on $customer->sources->data. note when retrieving customer object, attribute contain @ 10 sources. if customer has more 10 sources, need use pagination retrieve full list.

    note if use recent version of stripe's php library, can use auto-pagination feature handle easily.

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom
