By default, your Site will be set to use the Chargify Test Gateway. The Test Gateway is great for playing around, but in order to test your integration with a sandbox gateway, or to sell subscriptions using a real gateway, you will need to choose a gateway and enter your credentials.
When using the Chargify Test Gateway:
Any Site that is in test mode will only work with gateways accounts that are provided as test, developer, or sandbox accounts from your gateway provider. Usually, these “test” gateways use a different URL than their production counterparts, and Sites that are in test mode will only connect to these URLs.
Any Site that is in production mode will only work with real, live gateway accounts. If you are experiencing problems with incorrect credentials, ensure that you don’t have a mismatch between your Chargify Site mode (test vs. production) and your type of gateway (test vs. live)
You may only change gateways if the Site has no live subscriptions. If you need to change gateways, you may either create another Site, or cancel all of the subscriptions within your Site. If you are working with a test site, you may also consider clearing your Site data for a quick way to “reset” your Site and change gateways.
To set up your gateway and credentials, start by selecting the site you want to modify.
Next, click the Settings tab.
Click “Use this Gateway” next to the name of your gateway provider. Some providers may be disabled if they do not support the Site’s selected currency or if the site already has subscriptions.
Finally, enter your gateway credentials. All fields are required. The credentials requested for your gateway should be provided by your gateway, either via email or in their administrative interface. Be sure that you are entering your test credentials for a test site or live credentials for a production site.
