API Key Scopes

API keys are needed to authorize requests against some of the Crossmint HTTP APIs. By using an API key, Crossmint knows which project is making the call, and can deduct credits off your quota.

API key scopes are the permissions a key has to access or modify certain resources in your Crossmint developer project. It's a good security practice to enable only the permissions you need, and not more.


API keys are not needed to use Crossmint to accept credit card or cross chain payments

Crossmint's payment products do not require API keys. To use them follow the documentation under payments.

API key scopes can be configured from the API Keys section of the developer console. Please note that these are project based and you can have multiple keys with different levels of permissions.
