MasChain API Authentication

The MasChain API uses a custom API key header for authentication.

Authentication Header

Include your MasChain API key in the maschain-api-key header:

maschain-api-key: YOUR_MASCHAIN_API_KEY

API Key Management

MasChain API keys are managed by MasChain administrators. Contact the system administrator if you need a new MasChain API key or need to rotate existing keys.

warning

MasChain API keys have elevated privileges and can manage organisation API keys and contracts. Store them securely and never share them.

note

This authentication is different from the DApp API authentication which uses client_id and client_secret.
