Hubspot is a popular customer relationship management system. In order to request an integration between Hubspot and CardTapp, you will need to obtain your Hubspot API Key. Only Hubspot administrators can access this information.
Here's how to find your API key:
In the very top right corner of your screen, click on the round avatar icon to bring up your account menu.
Click on "Integrations".
Click on "HubSpot API key".
Click on "Generate new key".
Click on "Copy" to capture the API key via your clipboard. This identifier is what you will need to provide to CardTapp so that your integration can be configured.
