stripe firebase函數設置默認支付

Question

我想通過firebase函數設置添加到條帶的最後一張卡片作爲默認值，雖然我似乎無法使其工作。

// Add a payment source (card) for a user by writing a stripe payment source token to Realtime database 
exports.addPaymentSource = functions.database.ref('/users/{userId}/sources/{pushId}/token').onWrite(event => { 
    const source = event.data.val(); 
    if (source === null) return null; 
    return admin.database().ref(`/users/${event.params.userId}/customer_id`).once('value').then(snapshot => { 
    return snapshot.val(); 
    }).then(customer => { 
    return stripe.customers.createSource(customer, {source}); 
    return stripe.customers.update(customer, {default_source: source}); 
    }).then(response => { 
     return event.data.adminRef.parent.set(response); 
    }, error => { 
     return event.data.adminRef.parent.child('error').set(userFacingMessage(error)).then(() => { 
     // return reportError(error, {user: event.params.userId}); 
     consolg.log(error, {user: event.params.userId}); 
     }); 
    }); 
});

您試圖在此函數中返回兩件事。這是行不通的。它應該創建源，但不會更新它。

return stripe.customers.createSource(customer, {source}); 
return stripe.customers.update(customer, {default_source: source});
