Process card payments online with Stripe…
Cab Grid Pro has credit card payment processing built in via Paypal. However, there are some limitations to Paypal – such as currency and the countries where it is supported.
What’s more, we’ve done the integration work to provide a Stripe add-in plugin for Cab Grid Pro. This makes it super-easy to take card payments for journeys calculated through Cab Grid Pro.
Steps for setting up Stripe with Cab Grid Pro…
- Insure you have the latest version of Cab Grid Pro installed on your website (v4.3+ required)
- Sign up for a Stripe account
- Purchase and download the Stripe Add-on
- Install the Stripe Add-on on your website:
- Admin > Plugins > Add New > Upload Plugin
- Activate: Admin > Plugins > Installed Plugins > Cab Grid Stripe Integration > Activate
- Collect your API keys from Stripe (copy both TEST and LIVE publishable and secret API keys)
- Enter (paste) your API keys in the Cab Grid Stripe Integration settings page:
- Admin > Cab Grid Pro > Stripe
- Click ‘Save Changes’ button
- You may wish to configure other settings, such as the icon shown in the checkout window and the label on the checkout/pay button
The customer experience with Stripe enabled…
When the Cab Grid Pro Stripe Integration add-on plugin is installed and activated, customers will automatically be offered a payment button once their booking info has been submitted. This means the booking request will always be sent regardless of whether the payment is completed.
The ‘Booking Sent Message:’ under Cab Grid Pro > OPTIONS can be used to advise customers to complete their payment online. For example, you might enter a message like, “Please make a payment to guarantee this reservation…”
When a payment is successfully completed Stripe will email details. This should include the system reference number so you can marry the booking request email to the payment.
After the customer completes a Stripe payment they are shown the ‘Success Message’ configured under the Cab Grid Pro Stripe Integration settings page.
Maintain the Paypal Option…
Paypal can still be offered along-side Stripe. If you enter your Paypal email address under Cab Grid Pro > OPTIONS > Paypal ID & Currency, the Paypal button will also be shown. If you remove your Paypal ID, then the Paypal button will not show.
Configuring Cab Grid Pro Stripe Integration Options
The WordPress admin interface provides the following options. This is accessible by choosing the STRIPE tab on the main Cab Grid Pro admin page, or choosing the Stripe item in the Cab Grid Pro sub-menu in the WordPress Admin.
Choose the currency for Stripe transactions by selecting from the drop-down. This lists all currencies supported by Stripe.
This is independent of the currency symbol, which is set in the main Cab Grid Pro OPTIONS tab.
Surcharge/Deposit (charge amount variation)
Use a formula to adjust the price to apply a surcharge or deposit discount. Enter a formula in this box and it will be applied to the calculated price.
It is advisable to describe any price modifications in the ‘Booking Sent Message‘ field under the OPTIONS tab on the Cab Grid Pro admin page in WordPress.
If an additional fee should be charged for online Stripe transactions, this can be entered here.
Example 1: To add a fixed amount of $3.50, enter +3
Example 2: To add a 3 percent surcharge, enter *1.03
If a deposit (or part) payment is preferred instead of full payment, a formula can be defined to calculate the fee paid.
Example 1: To take a 15% deposit, enter *0.15
Example 2: To insure the deposit is not too low add a fixed amount enter *0.15+3 to charge 15% of full price and add $3.00.
Stripe can operate in either LIVE or TEST mode.
In TEST mode, only the test card number is valid (4242 4242 4242 4242). Any expiry date and CVC number (3 digits) can be used. Test mode simulates the functions of a real transaction without actually processing one.
In LIVE mode, only real valid card numbers are accepted and processed.
Stripe provides API keys for both LIVE and TEST modes. They are separate and distinct. Depending on what mode you have set, the interface will present fields for the appropriate API keys.
Publishable Key (LIVE/TEST)
The publishable key is required for Stripe to function. Stripe requires API keys for both LIVE and TEST modes. These are separate and distinct strings of characters.
Publishable API keys usually begin pk_test_ or pk_live_ and can be obtained from the Stripe dashboard after logging in.
To obtain either LIVE & TEST API keys you must click the switch labelled, “View Test Data” under the API menu on the left side of your Stripe Dashboard
Secret Key (LIVE/TEST)
The secret key is also required for Stripe to function properly on your site. Stripe requires API keys for both LIVE and TEST modes. These are separate and distinct strings of characters.
Publishable API keys usually begin sk_test_ or sk_live_ and can be obtained from the Stripe dashboard after logging in.
This is an image that is displayed at the top of the Stripe checkout box (as illustrated here with the Cab Grid icon).
Clicking the text box opens the media browser where you can either upload or select an image to be used.
This is text that is shown at the top of the Stripe checkout box. It would usually be your company name.
This is the text shown on the checkout buttons. There are two instances: Firstly, the button that opens the checkout box and, secondly, the button that submits the card details. The same text (as entered here) is used to label both buttons.
This is the message shown to visitors if the Stripe card transaction is successfully processed. It would potentially provide information or instructions concerning the booking.
Troubleshooting Problems with the Stripe Add-on for Cab Grid Pro
There is currently only one known issue that causes problems with the Stripe Add-on: Conflict with additional Stripe integrations.
An error message may appear like this:
Cannot declare class Stripe\Stripe, because the name is already in use
In this case, another plugin or theme that invokes Stripe can cause a fatal PHP error. From version 1.4.2 of the Stripe Add-on we attempt to mitigate this issue, but if the other plugin/theme does not account for this, the error will persist.
The only way to rectify this is to ask the other plugin or theme developer to update their code (or update it yourself).
