Piece authentication is used to gather user credentials and securely store them for future use in different flows. The authentication must be defined as the auth parameter in the createPiece, createTrigger, and createAction functions.

This requirement ensures that the type of authentication can be inferred correctly in triggers and actions.

Friendly Tip: Only at most one authentication is allowed per piece.

​
Secret Text

This authentication collects sensitive information, such as passwords or API keys. It is displayed as a masked input field.

Example:

PieceAuth.SecretText({
    displayName: 'API Key',
    description: 'Enter your API key',
    required: true,
    // Optional Validation
    validate: async ({auth}) => {
        if(auth.startsWith('sk_')){
            return {
                valid: true,
            }
        }
        return {
            valid: false,
            error: 'Invalid Api Key'
        }
    }
})

​
Username and Password

This authentication collects a username and password as separate fields.

Example:

PieceAuth.BasicAuth({
    displayName: 'Credentials',
    description: 'Enter your username and password',
    required: true,
    username: {
        displayName: 'Username',
        description: 'Enter your username',
    },
    password: {
        displayName: 'Password',
        description: 'Enter your password',
    },
    // Optional Validation
    validate: async ({auth}) => {
        if(auth){
            return {
                valid: true,
            }
        }
        return {
            valid: false,
            error: 'Invalid Api Key'
        }
    }
})

​
Custom

This authentication allows for custom authentication by collecting specific properties, such as a base URL and access token.

Example:

PieceAuth.CustomAuth({
    displayName: 'Custom Authentication',
    description: 'Enter custom authentication details',
    props: {
        base_url: Property.ShortText({
            displayName: 'Base URL',
            description: 'Enter the base URL',
            required: true,
        }),
        access_token: PieceAuth.SecretText({
            displayName: 'Access Token',
            description: 'Enter the access token',
            required: true
        })
    },
    // Optional Validation
    validate: async ({auth}) => {
        if(auth){
            return {
                valid: true,
            }
        }
        return {
            valid: false,
            error: 'Invalid Api Key'
        }
    },
    required: true
})

​
OAuth2

This authentication collects OAuth2 authentication details, including the authentication URL, token URL, and scope.

Example:

PieceAuth.OAuth2({
    displayName: 'OAuth2 Authentication',
    grantType: OAuth2GrantType.AUTHORIZATION_CODE,
    required: true,
    authUrl: 'https://example.com/auth',
    tokenUrl: 'https://example.com/token',
    scope: ['read', 'write']
})

Please note OAuth2GrantType.CLIENT_CREDENTIALS is also supported for service-based authentication.
