OpenAPI

Overview

openapi.php is the JSON API endpoint based on the OpenAPI specification.

The API uses the existing API keys:

• Full API key: APIKEY
• Read-only API key: READONLYAPIKEY

Both global and tenant-level keys are supported.

The implemented API objects are extension, voicemail, condition, huntlist, did, and queue. They provide endpoints for listing, retrieving, creating, modifying, and deleting configuration records.

OpenAPI Specification

The OpenAPI specification is available from:

openapi.php
openapi.php?spec=1
openapi.php/openapi.json
openapi.php/swagger.json

The response is an OpenAPI 3.0.3 JSON document.

Authentication

The API key can be provided in any of these ways.

Query Parameter

openapi.php/extensions?tenant=TENANTCODE&key=APIKEY

Header

X-API-Key: APIKEY

Bearer Token

Authorization: Bearer APIKEY

API Key Scope

Tenant API Key

When using a tenant-level API key, the tenant parameter is required.

openapi.php/extensions?tenant=TENANTCODE&key=TENANT_API_KEY

Global API Key

When using a global API key, tenant is optional.

If tenant is provided, only that tenant's records are returned.

If tenant is omitted, records from all tenants are returned for list and get requests.

openapi.php/extensions?key=GLOBAL_API_KEY

List Extensions

Endpoint

GET openapi.php/extensions

Alternative compatibility format:

openapi.php?object=extension&action=list

Parameters

Name	Required	Description
key	Yes, unless using header authentication	Full or read-only API key
tenant	Required for tenant keys	Tenant code or tenant name

Example Request

curl "https://pbx.example.com/openapi.php/extensions?tenant=TENANTCODE&key=APIKEY"

Using header authentication:

curl \
  -H "X-API-Key: APIKEY" \
  "https://pbx.example.com/openapi.php/extensions?tenant=TENANTCODE"

Using bearer authentication:

curl \
  -H "Authorization: Bearer APIKEY" \
  "https://pbx.example.com/openapi.php/extensions?tenant=TENANTCODE"

Example Response

[
  {
    "id": 101,
    "number": "100",
    "name": "Reception",
    "tech": "PJSIP"
  },
  {
    "id": 102,
    "number": "101",
    "name": "Office",
    "tech": "SIP"
  }
]

Response Fields

Field	Type	Description
id	integer	Extension internal ID
number	string	Extension number
name	string	Extension display name
tech	string	Extension technology, for example SIP, PJSIP, VIRTUAL, or CUSTOM

Get Extension Information

This endpoint returns detailed information for one extension.

The extension can be selected by internal extension ID or by extension number.

When using the global full API key, the response also includes the extension password when a password exists for the extension technology.

Tenant API keys and read-only API keys do not return the extension password.

Endpoints

Get an extension by ID:

GET openapi.php/extension?id=EXTENSION_ID

Alternative path format:

GET openapi.php/extensions/EXTENSION_ID

Get an extension by number:

GET openapi.php/extension?number=EXTENSION_NUMBER

Alternative path format:

GET openapi.php/extensions/number/EXTENSION_NUMBER

Alternative compatibility format:

openapi.php?object=extension&action=info&id=EXTENSION_ID
openapi.php?object=extension&action=info&number=EXTENSION_NUMBER

Parameters

Name	Required	Description
key	Yes, unless using header authentication	Full or read-only API key
tenant	Required for tenant keys	Tenant code or tenant name
id	Required if number is not provided	Extension internal ID
number	Required if id is not provided	Extension number

Use either id or number, not both.

When using a global API key without the tenant parameter, selecting by extension number can match more than one tenant. In that case the request returns an error and the request should be repeated using the tenant parameter or the extension ID.

Example Requests

Get by ID:

curl "https://pbx.example.com/openapi.php/extension?id=101&tenant=TENANTCODE&key=APIKEY"

Get by number:

curl "https://pbx.example.com/openapi.php/extension?number=100&tenant=TENANTCODE&key=APIKEY"

Using header authentication:

curl \
  -H "X-API-Key: APIKEY" \
  "https://pbx.example.com/openapi.php/extension?number=100&tenant=TENANTCODE"

Example Response

The response includes all fields from the extension table, the normalized fields id, number, name, and tech, the current state when available, the technology username, technology-specific details, and related records.

Related records are returned in the related object. Depending on the extension configuration, this can include state information, registrations, PJSIP contacts, call groups, pickup groups, destinations, queue membership, allowed queue membership, user profile, routing profiles, client rate, caller ID regex, music on hold, parking lot, conditions, media files, and associated phones.

The me_data binary field from media files is not returned in this response.

Additional Configuration Objects

The following objects use the same authentication and HTTP behavior as extensions.

Object	List Endpoint	Single Endpoint	ID Field	Main Table
voicemail	GET openapi.php/voicemails	openapi.php/voicemail?id=ID	uniqueid	voicemail
condition	GET openapi.php/conditions	openapi.php/condition?id=ID	co_id	co_conditions
huntlist	GET openapi.php/huntlists	openapi.php/huntlist?id=ID	hu_id	hu_huntlists
did	GET openapi.php/dids	openapi.php/did?id=ID	di_id	di_dids
queue	GET openapi.php/queues	openapi.php/queue?id=ID	qu_id	qu_queues

Generic Endpoints

Use the plural path for list and create operations:

GET openapi.php/voicemails
POST openapi.php/voicemails
GET openapi.php/conditions
POST openapi.php/conditions
GET openapi.php/huntlists
POST openapi.php/huntlists
GET openapi.php/dids
POST openapi.php/dids
GET openapi.php/queues
POST openapi.php/queues

Use either the singular endpoint with an id parameter or the plural path with the ID:

GET openapi.php/voicemail?id=ID
PATCH openapi.php/voicemail?id=ID
DELETE openapi.php/voicemail?id=ID

GET openapi.php/voicemails/ID
PATCH openapi.php/voicemails/ID
DELETE openapi.php/voicemails/ID

The same pattern applies to condition, huntlist, did, and queue.

Alternative compatibility format:

openapi.php?object=voicemail&action=list
openapi.php?object=voicemail&action=info&id=ID
openapi.php?object=voicemail&action=create
openapi.php?object=voicemail&action=modify&id=ID
openapi.php?object=voicemail&action=delete&id=ID

Generic Request Body

The body is JSON. Fields can be supplied using the database column names used by the web pages.

Short aliases are supported where they are unambiguous:

Object	Alias	Field
voicemail	number	mailbox
voicemail	name	fullname
condition	name	co_name
condition	type	co_type
huntlist	name	hu_name
huntlist	number	hu_number
did	number	di_number
queue	name	qu_name

Destinations

Objects that use destinations accept a destinations object. Each destination item can be either a string in TYPE-ID format or an object with type and id.

{
  "di_number": "390212345678",
  "di_comment": "Main number",
  "destinations": {
    "DID": ["EXT-101"],
    "DID-UNCONDITIONAL": [
      { "type": "VOICEMAIL", "id": 10 }
    ]
  }
}

Supported destination keys:

Object	Destination Keys
voicemail	VOICEMAIL-OPERATOR, VOICEMAIL-FOLLOW, VOICEMAIL-BROADCAST
condition	CONDITION, NOTCONDITION, and CONDITION1 through CONDITION20
huntlist	HUNTLIST, HUNTLIST-TIMEOUT
did	DID, DID-UNCONDITIONAL, DID-SMS, DID-FAXSUCCESS
queue	QUEUE-FULL, QUEUE-TIMEOUT, QUEUE-EXITKEY, QUEUE-ONCALLBACK, QUEUE-NOBODYHOME, QUEUE-NOFREEMEMBER, QUEUE-PERIODICANNOUNCE, QUEUE-BEFORERINGING, QUEUE-ONAUTOPAUSE, QUEUE-ONABANDONEDCALL

Related Records

Get responses include a related object when the object has related configuration.

For conditions, related.extended_infos contains rows from ce_conditions_extended. Create and modify requests can replace these rows by sending extended_infos.

For queues, related.realtime contains the realtime queue row. Create and modify requests can send realtime queue fields either at the top level or nested under queue or realtime. Queue members can be replaced by sending members, queue_member, or queue_members. Allowed queue members can be replaced by sending allowed_members, aq_allowed_queue_member, or allowed_queue_members.

For hunt lists, create and modify requests update the matching follow-me records used by the dialplan.

Examples

Create a voicemail:

curl \
  -X POST \
  -H "Content-Type: application/json" \
  -H "X-API-Key: APIKEY" \
  -d '{"mailbox":"200","fullname":"Sales","password":"1234","email":"sales@example.com"}' \
  "https://pbx.example.com/openapi.php/voicemails?tenant=TENANTCODE"

Modify a DID destination:

curl \
  -X PATCH \
  -H "Content-Type: application/json" \
  -H "X-API-Key: APIKEY" \
  -d '{"destinations":{"DID":["EXT-101"]}}' \
  "https://pbx.example.com/openapi.php/did?id=25&tenant=TENANTCODE"

Create a queue with realtime fields:

curl \
  -X POST \
  -H "Content-Type: application/json" \
  -H "X-API-Key: APIKEY" \
  -d '{"qu_name":"Support","qu_number":"700","queue":{"strategy":"ringall","timeout":20},"members":[{"membername":"100","interface":"Local/AG-000-NF-101@fromotherpbx/n","state_interface":"Custom:100","member_device":"100","penalty":0,"paused":0}]}' \
  "https://pbx.example.com/openapi.php/queues?tenant=TENANTCODE"

Change Logging

Create, modify, and delete operations write a process log entry and a user activity log entry using the OpenAPI user label. Related destination, condition, queue member, and queue realtime changes are also logged where applicable.
