Overview
IP Fabric is an API-first client, which means that every click in the user interface (UI) has an associated API call.
Python IP Fabric (SDK)
API-first principles allow the IP Fabric team to maintain a Software Development Kit (SDK) that can be used for automation. While the IP Fabric main GUI is written in TypeScript, we have chosen to write the SDK in Python, as it is the most common language used by network engineers.
The SDK documentation can be found at https://gitlab.com/ip-fabric/integrations/python-ipfabric.
While using SDK is more straightforward than calling API directly, we recommend making yourself familiar with the rest of the documentation, as many SDK calls map directly to API calls.
Postman Collection
An IP Fabric Postman Collection is also available for testing API calls. The collection can be found in the IP Fabric Public Workspace, and documentation can be found here in Postman Collection.
Using API Directly
The following documentation is meant to get you started working with the API and provide you with a tutorial on how it works.
Most of the tables within IP Fabric have a Table description
option under the
...
(3-dot menu) in their top-right corner. It describes how to interact with
the API, the data required in the payload, and the endpoint to send the request
to. This is the easiest way to learn how to use the API. For more information,
please see
Table Description.
Another option is to use the Network
tab of the web
browser’s Developer tools
, which will show you the endpoints and data required
to make a successful call to the platform.

API Versioning
Starting with version 5.0
, we have adopted a rather fast-moving API versioning
schema. This allows for tighter control over the changes and provides an
opportunity for maintaining backward compatibility for a manageable time frame.
The design still leverages API version directly in the URL over alternative approaches, such as the extended Accept header. This allows for unambiguous exchange of state between IP Fabric and customers; nothing more than the URL is needed to identify the resource being accessed.
URL Schema a Version in URL
The URL schema looks like:
https://{hostname}/api/v{major}.{minor}/{resource_path}
we use the following shortened version throughout the documentation:
/api/{api_version}/{resource_path}
where:
major
andminor
follow the release version of the platform. So, if version4.4.3
of the IP Fabric platform is deployed, its latest API path would be/api/v4.4/
.
- The whole
.{minor}
is optional, and it is treated as0
if omitted.
{api_version}
stands for the complete version string. For example,v5.1
. Please mind thev
prefix.
API Version Deprecation and Allowed Changes
IP Fabric commits to keeping support for all minor
versions within the particular
major
version (so, for example, in version 5.4.3
, we allow /api/v5.1/
calls). But API may break between major releases.
We call a major release a release that introduces some complex functionality.
This typically means a large code refactoring, changes to the data model, etc.
Keeping backward compatibility is frequently not feasible in such
cases (for example, v3
brought support for snapshots, v4
brought graphs, v5
RBAC).
Naturally, backward-compatible changes (typically addition of a new attribute) don’t need to be gated and can appear in responses even when an older API version is used within the request.
Changes and depreciations are communicated via the API documentation
and release notes. We will mark attributes
as deprecated: true
in the OpenAPI schema when we fully migrate to the OpenAPI
3.0+ Specification.
Responses made with minor < release_minor
will contain a custom header warning
the client about the use of a potentially old API. We leverage
the IETF Draft for Deprecation header. It is included and set to true
(Deprecation: true
) in every response to
a call made with an older than the current API version.
Requests made with major < release_major
(obsolete version) will be refused
with the HTTP code 410 Gone
(406 Not Acceptable
would also be reasonable, but we
explicitly mention this in the apidoc in relationship with the Accept
header; so
not to confuse these two, the 410
was selected).
Requests made with an API version newer than the currently supported version are
also refused with 410 Gone
(while 404
or 406
would be probably closer
semantically, we don’t want to confuse clients and keep 410
for all
version-related errors).
The error body, in both cases, is a JSON depicting current platform version as well as the current API version:
{
"message": "Unsupported API version used.",
"release_version": "5.4.2+1",
"api_version": "v5.4"
}
This may look excessive at first, but it is to promote the client code to be changed with every update, as to keep track with all small changes and updates we bring. But in reality, clients would typically be fine if they update the API version when moving to the new major release only. Frequently, the client code will not change, except for the API version. Thus, we recommend using a global constant for it.
Technology Table Endpoints
The technology tables use POST
requests only for reading information, and
the payload is used to specify or filter requested data from listed tables. The
POST
and DELETE
requests can be used for intent verification rules at each
endpoint.
At a technology table, click ...
(3-dot button) in the top right corner of the
table and select the Table description
option that exposes the endpoints (can
be used with filters as well):
Payload Definition
{
"attributeFilters": {},
"columns": ["id", ...],
"filters": {},
"pagination": {},
"snapshot": "<UUID|$last|$prev|$lastLocked>",
"reports": "<FRONTEND_URL>" | ["REPORT_ID"]
}
columns
– Specifies columns that we request for the endpoint.filters
– (Optional) Filtering options, for any column or intent verification.- Example:
"filters": {"vendor":["like","cisco"],"family":["eq","lap"],"reload":["color","eq","0"]}
- Example:
pagination
– (Recommended) Specifies the pagination and response limits.- Example:
{"limit":1000,"start":0}
- It is currently recommended to query 1000 rows or fewer at a time.
- Example:
snapshot
– Specify the snapshot ID or use:$last
,$prev
,$lastlocked
- Note: some tables (i.e., settings) do not allow the
snapshot
parameter.
- Note: some tables (i.e., settings) do not allow the
reports
– (Optional) Frontend URL where the reports are displayed or an array of report IDs as strings.- Examples:
"reports": "/inventory/devices"
"reports": ["304796641"]
- Examples:
attributeFilters
– (Optional) Applies an attribute filter to the table.- Example:
"attributeFilters": {"siteName": ["LAB01"]}
- Note: some tables (i.e., settings) do not allow the
attributeFilters
parameter.
- Example:
