When Nutshell launched in 2010, open API access was at our core. Today, we’re launching broad new swaths of API access via REST API, with a comprehensive documentation and testing suite (powered by Readme.com). This will enable easier integrations between Nutshell and other tools and give you more control over how you use the platform.
How will the new REST API documentation benefit my team?
We’ve made it easier to access data with better filtering and searching capabilities via our new list APIs. We’ve expanded the availability to access and filter Nutshell timelines. And our REST API powers much of our application, so we will continue to publish more documentation for new capabilities inside Nutshell.
The new documentation also includes an API console so you can test REST API requests with live data and experiment with what’s possible.
Other integration points
In addition to this new REST API and documentation suite, Nutshell integrates through a number of other channels:
We continue to support and maintain our existing JSON-RPC API. Those docs live inside our new developer site
Nutshell Enterprise comes with read-only SQL access for the deepest data access
Our Zapier integration grows every month (we just added a “Log an activity” action)
Webhooks allow you to subscribe to pushes from Nutshell when your data changes
Any saved Nutshell list can be exported as a CSV file
How can I get started with REST API?
If your team is interested in accessing Nutshell’s REST API, our developer website is the resource you need to find guides and documentation for getting started.
FAQs about Nutshell’s REST API
What’s the difference between Nutshell’s REST API and JSON-RPC API?
REST API is resource-based and uses standard HTTP methods (GET, POST, PUT, DELETE), making it easier to learn and more cache-friendly. JSON-RPC is action-based and calls specific functions. REST is ideal for modern integrations and third-party tools, while JSON-RPC offers more flexibility for complex, function-driven workflows.
What can I build with Nutshell’s REST API?
You can build custom integrations to sync Nutshell data with other business tools, automate lead capture from web forms, create custom dashboards and reports, build mobile apps that access your CRM data, and connect Nutshell to accounting software, marketing platforms, or project management tools for seamless data flow.
Do I need to be a developer to use Nutshell’s REST API?
Not necessarily. While the REST API is designed for developers, you can use no-code tools like Zapier to connect Nutshell with other apps without writing code. For custom integrations, you’ll need development skills or can work with a developer to build what you need.
How do I get started with Nutshell’s REST API?
Visit developers.nutshell.com for comprehensive documentation and guides. You’ll need to generate an API key from your Nutshell account, then use the API console to test requests with live data. The documentation includes authentication details, endpoint references, and code examples to help you get up and running quickly.
Is Nutshell’s REST API available on all plans?
The REST API is available on the Enterprise plan, which starts at $79 per user per month (billed annually). Enterprise includes API support, read-only SQL access, and unlimited custom fields. All other Nutshell plans can still integrate using Zapier, webhooks, CSV exports, and the JSON-RPC API.
