Use the Crossmint connector to integrate NFT and blockchain-based digital assets.
Integrating your application with Crossmint lets you use these operations in an automation. It exposes 26 actions, listed below. Add the connector from the Connections area, authenticate, then select its operations in the automation builder. Capabilities: actions.
Authentication
Before you begin, make sure you have the following information:
Connection Name: Choose a meaningful name for your connection. This name helps you identify the connection within your application or integration settings.
Authentication Type: The authentication method for this connector is defined in the connection setup. Select the connector in the Connections area to see the fields it requires.
Obtaining Your API Key
Log in to the Crossmint console at crossmint.com/console (use staging.crossmint.com/console if you want a staging/test key first).
Open your project, then go to the API Keys page.
In the Server-side keys section, click Create new key.
Toggle on the scopes this connector needs, such as the collections and NFT scopes, then click Create server key.
Copy the generated API key and store it securely. Production keys are shown only once — once you close the dialog or navigate away, you can't view the key secret again.
