Overview

Integration → Call API supports initiating a call and downloading of call recording via HTTP requests: 

Dial parameters

• outbound queues are supported via prefixes, in the same way as dialed from a desk phone
• to notify a 3rd party about call events via HTTP callbacks configure URL adapter parameter in the link:
  
  
• an example of URL adapter for event handling:
  
  
• to create a sample URL adapter paste the following link onto the form (parameters will be parsed automatically) 

​https://test/identity.asp?CallType={{CallTypeName}}&Event={{DialApiEventName}}&CallID={{CallID}}&RequestID={{DialApiRequestID}}&EventCode={{DialApiEventCode}}&IsCallRecorded={{IsCallRecorded}}&Guid={{CallUUID}}

Linking events to calls

• the dial API returns an integer request ID as JSON ({RequestID:00000}), for example
  
  
• this RequestID is passed to the event callback via {{DialApiRequestID}} placeholder in the corresponding URL adapter
• the adapter also supports {{CallID}} placeholder which together with the {{DialApiRequestID}} allow to link calls to the corresponding API request
• every call to the dial API initiates a pair calls: one to dial the agent and another to dial the requested number, for example
  ​
  
• in the event callback there are 2 placeholders available to differentiate between different events belonging to those calls: {{CallTypeName}} and {{DialApiEventName}} (see the table below)

Some examples of event callback requests made via the sample adapter described above:

https://test/identity.asp?CallType=API&Event=pickup&CallID=1000000087849&RequestID=513&EventCode=2&IsCallRecorded=&Guid=bfa2dbc8-ab8a-34c8-f243-c2aad8c446ff
https://test/identity.asp?CallType=Outgoing&Event=pickup&CallID=1000000087850&RequestID=513&EventCode=2&IsCallRecorded=&Guid=923041af-adb5-a8ae-f29c-e60ea5e17448
https://test/identity.asp?CallType=Outgoing&Event=hangup&CallID=1000000087850&RequestID=513&EventCode=1&IsCallRecorded=1&Guid=923041af-adb5-a8ae-f29c-e60ea5e17448
https://test/identity.asp?CallType=API&Event=hangup&CallID=1000000087849&RequestID=513&EventCode=1&IsCallRecorded=1&Guid=bfa2dbc8-ab8a-34c8-f243-c2aad8c446ff

The above examples are for the pair of calls (API and Outgoing) generated via a single request to the dial API that returned {RequestID:513} where both the agent and the dialed party picked up the call.
