URL FormatFormat
Code Block |
---|
<http/https>://<my_server>:<port_number>/<version>/<endpoint>/[resource_id]/[association][?args] |
Elements in square brackets [brackets]
are are optional.
Element | Description | Example | ||
---|---|---|---|---|
<http/https> | HTTP protocol identifier. The protocol should be | https | ||
<my_server> | Name of the
| myapp.example.com | ||
<port_number> | Port number over which you access the
3005 . | 3005 | ||
<version> | API version number.
| v4 | ||
<endpoint> | Name of the API endpoint to use. | /connections | ||
[resource_id] | Internal identifier for the specific resource requested from the endpoint. This value defines the object against which the requested operation is performed. | /10 | ||
[association] | If applicable, the association identifiers the API endpoint that is requested using the context determined by the Associations can also be referenced by query parameter. See Embedding Associations below. | /jobGroups | ||
[?args] | In some cases, arguments can be passed to the endpoint in the form of query parameters. | ?arg1=value1&arg2=value2 |
...
Naming Conventions
- Resource names are plural and expressed in camelCase.
- Resource names are consistent between main URL and URL parameter.
...
Parameter lists are consistently enveloped in the following manner:
Code Block { "data": [ { ... } ] }
- Field names are in in
camelCase
and are consistent with the resource name in the URL or with the theembed
URL parameter.
- From early API versions, foreign keys have been replaced with identifiers like the following:
...
Support for basic CRUD (Create, Read, Update, and Delete) operations across most platform objects.

NOTE: Some of these specific operations may not be supported in the current release. For a complete list, see API Endpoints. |
Operation | HTTP Method | Example URL | Notes |
---|---|---|---|
Create | POST | /v4/people | |
POST | /v4/connections | ||
Read | GET | /v4/people/1 | 1 = internal user Id |
GET | /v4/connections/10 | 10 = internal connection Id | |
GET | /v4/people/1/flows | ||
List | GET | /v4/people | |
GET | /v4/connections | ||
Update | PATCH | /v4/people/1 | Partial replacement |
PATCH | /v4/connections/10 | Partial replacement | |
PUT | /v4/people/1 | Full replacement | |
PUT | /v4/connections/10 | Full replacement | |
Delete | DELETE | /v4/people/1 | |
DELETE | /v4/connections/10 |
...
An association can be referenced using the above URL structuring or by applying the embed
query query parameter as part of the reference to the specific resource. In the following example, the sub-jobs of a jobGroup are embedded in the response for jobGroup=1:

---|
https:/myapp.example.com//v4/jobGroups/1?embed=jobs |
...

The id
value value of the association is always included in the response.

HTTP Status Codes and Errors
Request Method | Request Endpoint | HTTP Status Code (success) |
---|---|---|
POST | /v4/<resource> | 201 Created |
GET | /v4/<resource> | 200 OK |
GET | /v4/<resource>/<id> | 304 Not Modified when client has cached version. See Caching below. |
PATCH | /v4/<resource>/<id> | 200 OK |
PUT | /v4/<resource>/<id> | 200 OK |
DELETE | /v4/<resource>/<id> | 204 No Content |
The following error codes can apply to any of the above requests:
Info |

NOTE: 5xx status codes may be generated by the server. |
HTTP Status Code (client errors) | Notes |
---|---|
400 Bad Request | Potential reasons:
|
403 Forbidden | Incorrect permissions to access the Resource. |
404 Not Found | Resource cannot be found. |
410 Gone | Resource has been previously deleted. |
415 Unsupported Media Type | Incorrect Accept header. |
Caching
When a resource has been cached in the client, the client may set an If-Modified-Since
header header in HTTP date format on the request. If so:
General Response | HTTP Status Code |
---|---|
Returns full modified resource | 200 OK |
Returns an empty response for unmodified resource | 304 Not Modified |
Use Cases
REST API Tasks
By chaining together sequences of calls to API endpoints, you can create, read, update, and delete objects using identifiers accessible through the returned JSON. For more information, see API Endpoints.
