Build your own integration

If the system you want to connect isn’t in the integrations list, you can build your own connection with the Fiddle REST API. It exposes the same core data — items, stock, orders, and more — so you can read and write programmatically.

Get started

1. Generate an API key in Fiddle under Settings.
2. Authenticate your requests with that key.
3. Read the reference documentation to find the endpoints you need.
4. Build and test against your own account before going live.

What you can do

• Read and update items, stock levels, and locations.
• Create and read orders to route them in and push updates back out.
• Automate workflows between Fiddle and your other systems.

Keep API keys secret and rotate them if one is exposed. Treat them like passwords.

API requests are rate limited. Send a valid API key with every request to get the higher limit, and handle retries gracefully.

Visit the developer documentation for the full API reference, authentication details, and examples. If a prebuilt connection covers your needs instead, check the Integrations overview first.
