Configuration

import { withSapiom } from '@sapiom/axios';

const client = withSapiom(axiosInstance, {
  // Required (or use SAPIOM_API_KEY environment variable)
  apiKey: 'sk_...',

  // Optional - Control
  enabled: true,              // Enable Sapiom handling (default: true)
  failureMode: 'open',        // 'open' | 'closed' (default: 'open')
                              // 'open': Allow requests if Sapiom fails (prioritizes availability)
                              // 'closed': Block requests if Sapiom fails (prioritizes security)

  // Optional - Default metadata (applied to all requests)
  agentName: 'my-agent',      // Agent identifier
  agentId: 'agent-123',       // Agent UUID or numeric ID
  serviceName: 'my-service',  // Service name for transactions
  traceId: 'trace-xyz',       // Internal trace UUID
  traceExternalId: 'ext-456', // External trace identifier
});

Per-Request Overrides

Override configuration for individual requests using the __sapiom property:

// Disable Sapiom for a specific request
await client.get('/public-endpoint', {
  __sapiom: { enabled: false }
});

// Override metadata for a specific request
await client.post('/api/resource', data, {
  __sapiom: {
    serviceName: 'different-service',
    actionName: 'custom-action',
    traceExternalId: 'ext-789'
  }
});
