The Nautobot REST API provides a powerful interface for integrating, automating, and managing network infrastructure. Below is a step-by-step overview of the key components and usage patterns.

1. API Endpoint Structure
   • The base API endpoint is: https://<hostname>/api/
   • Major resources are organized by app modules such as dcim, ipam, and tenancy.
   • Example: To list devices, use: /api/dcim/devices/
2. HTTP Methods
   • GET: Retrieve data from Nautobot.
   • POST: Create a new object or resource.
   • PUT/PATCH: Update an existing object.
   • DELETE: Remove a resource from the system.
3. Authentication & Authorization
   • API tokens are used for secure authentication. Include in the request header:

     Authorization: Token <your_api_token>

   • Supports session authentication for UI browsing.
4. API Versioning
   • Specify the API version using the Accept header or api_version URL parameter.
   • Example Header:

     Accept: application/json; version=2.0

   • Example URL: /api/dcim/devices/?api_version=2.0
5. Filtering & Pagination
   • Use query parameters to filter results.
   • Example:
     /api/dcim/interfaces/?device=<device_uuid>
   • Pagination follows a standard limit/offset style.
6. Example API Call
   • To retrieve details of a specific IP address:

     curl -s http://nautobot/api/ipam/ip-addresses/<uuid>/ | jq '.'

     This returns a JSON payload with all attributes and links to related objects.
7. Interactive API Documentation
   • An interactive API playground is available at /api/docs/ on your Nautobot instance, supporting exploration and live testing.

The REST API is the best choice for full CRUD automation, provisioning, and systems integration workflows.

The Nautobot GraphQL API delivers a streamlined, read-only interface for querying exactly the data you need, with minimal overhead and deep flexibility. Here is a step-by-step explanation of its core usage and functionality.

1. GraphQL API Endpoints
   • Interactive Explorer: /graphql/ offers an in-browser playground (GraphiQL) with autocompletion and documentation.
   • Programmatic Use: /api/graphql/ is designed for API clients and applications.
2. Authentication
   • Use the same API token as for REST calls, included in the request header:

     Authorization: Token <your_api_token>

3. Read-Only Queries
   • The GraphQL API is designed for data retrieval—mutation and delete operations are not supported.
4. Query Structure and Variables
   • Send HTTP POST requests with JSON that includes a query string and optional variables object.
   • Example JSON request:

     {
       "query": "query ($id: Int!) { device(id: $id) { name } }",
       "variables": { "id": 3 }
     }

   • Basic GraphQL query format:

     query {
       devices {
         name
         site { name }
         primary_ip4 { address }
       }
     }

5. Filtering and Pagination
   • Filter at any level of the query by passing arguments:

     query {
       devices(location: "ams01", limit: 1, offset: 1) {
         name
       }
     }

   • Use limit and offset to manage large datasets and control result size.
6. Relationships and Nested Queries
   • Traverse relationships directly with nested field queries.
   • Example – Filter devices and show interfaces named "GigabitEthernet1/1":

     query {
       devices(role: "edge", limit: 2) {
         name
         interfaces(name: "GigabitEthernet1/1") {
           name
           status
         }
       }
     }

7. GraphiQL: Building and Testing Queries
   • The GraphiQL interface offers autocomplete, schema documentation, and instant feedback for query development.
   • Easily adapt and validate queries before integrating them into scripts/clients.
8. Saving and Managing Queries
   • Saved queries can be managed and executed from the Data Management section in Nautobot.
   • Saved queries can also be executed via API endpoints for automation or reporting.

The Nautobot GraphQL API is ideal for efficient, customized reporting and dashboarding, providing rapid access to complex, deeply linked data with a single request.

Employing best practices helps you leverage the Nautobot GraphQL API effectively, ensuring robust, optimized, and maintainable queries. Here’s a step-by-step approach to getting the most out of GraphQL.

1. Use GraphiQL for Query Design
   • Build and test queries in the interactive GraphiQL interface (/graphql/) before moving them into automation scripts or applications.
   • Take advantage of autocompletion and schema documentation for reliable query construction.
2. Favor Variable-Based Queries
   • Structure queries to use variables instead of hardcoded values for better flexibility and code reusability.
   • This method makes automation scripts and dashboard code easier to read and update.
3. Filter and Limit Results
   • Use filters within queries to narrow down the result set and only fetch necessary data.
   • Apply limit and offset arguments to handle large datasets efficiently and avoid overloading client applications.
4. Select Only Required Fields
   • Specify only the fields you need in your query to minimize response size and improve performance.
   • Avoid requesting entire objects unless all data is necessary for your task.
5. Traverse Relationships Thoughtfully
   • Leverage GraphQL’s ability to traverse related data; nest fields carefully to reduce redundant or excessive data retrieval.
   • Plan nested queries to target relevant relationships rather than retrieving broad swathes of data.
6. Test, Document, and Save Queries
   • Always validate queries in GraphiQL or with test scripts before deployment.
   • Document complex queries for future reference and team use.
   • Save and reuse commonly used queries for reporting, dashboards, or automation.

Following these best practices ensures efficient, maintainable, and robust integration with Nautobot’s GraphQL API, supporting your automation, reporting, and data retrieval needs.

Even with robust APIs, issues can arise during integration or daily use. This troubleshooting guide leads you through the most common problems encountered with Nautobot's REST and GraphQL APIs, along with practical steps to resolve them.

1. API Authentication Issues
   • Double-check your API token for typos or omissions.
   • Ensure tokens have not expired or been revoked.
   • Verify that the token is included properly:

     Authorization: Token <your_api_token>

2. Version Mismatch and Breaking Changes
   • Always specify the API version your application depends on, using the Accept header or api_version URL parameter to avoid unexpected changes.
   • If you encounter unknown fields or failed requests after an upgrade, consult the instance’s API documentation to review any breaking or non-breaking changes.
3. Permissions and Access Problems
   • Confirm your user or token has the correct permissions for the desired endpoints and actions.
   • For denied access errors (like HTTP 403), review Nautobot’s permission model for the affected resource type.
4. Malformed Requests
   • Validate your request body is formatted as expected—use JSON for both REST and GraphQL requests.
   • For REST, ensure required fields and valid data types are provided.
   • For GraphQL, use the GraphiQL interface to build and check query syntax.
5. Filtering, Pagination, and Performance
   • When retrieving large data sets, use limit and offset pagination parameters to reduce response size and load.
   • Exclude many-to-many fields if performance is impacted by large nested datasets.
   • Narrow down results with filters instead of broad queries.
6. Handling Error Messages
   • Review HTTP status codes (e.g., 400, 403, 404, 500) and error messages in responses for clues.
   • Utilize error IDs (when present) to cross-reference solutions in Nautobot documentation or plugin guides.
   • Log requests and responses for failed calls to assist in debugging.
7. Common GraphQL Pitfalls
   • Ensure your queries only request supported fields—unsupported or misspelled fields will cause errors.
   • Remember that GraphQL endpoints are read-only; create, update, or delete operations must use the REST API.
   • Large or deeply nested queries can impact performance; break them up for better results.
8. API Connectivity Troubles
   • Test basic connectivity to your Nautobot instance (via ping or curl).
   • Ensure any proxies or firewalls are not blocking API access or redirecting requests.
9. Where to Find Help
   • Consult the interactive API docs (`/api/docs/` for REST or `/graphql/` for GraphQL) for up-to-date schemas and usage.
   • Search official documentation, community forums, or Nautobot discussions for known issues and solutions.
   • Use logging and error IDs to speed up support requests.

Methodical troubleshooting using these steps will resolve most integration issues and keep your Nautobot API automations running smoothly.
