Instead of embedding Layer’s React components, you can build your own interface directly on top of the Layer API. This gives you full control over the look, feel, and behavior of every accounting experience in your product. The API Reference is the complete resource for building custom UIs. At a high level:
  • Authenticate. Follow Authentication to obtain an access token. For client-side apps, mint business-scoped access tokens on your backend so the browser never holds your client_secret.
  • Read and write data. Use the API to fetch reports, list and categorize transactions, and manage invoices, bills, and more.
  • Stay in sync. Subscribe to webhooks so your UI updates as data changes in Layer.
Reach out to your Layer contact if you’d like guidance on building a specific custom experience.
