Outbound REST Payload Maps
Outbound REST Payload Maps
To query specific records from disparate third-party systems, Asterisk 2 implements customizable outbound network schemas. The integration engine compiles template properties into verified JSON string payloads before dispatching socket frames.
Dynamic Request Serialization Pipeline
The flowchart below maps out how logical call properties compile into outgoing HTTP request blocks:
graph LR
%% Data Source
subgraph ActiveContext["Live Call Context Store"]
VarCaller["CallerID String<br/>(Value: '9001')"]
VarLang["Language string<br/>(Value: 'en')"]
end
%% Schema Mapping
subgraph MappingEngine["JSON Payload Synthesizer"]
MapSchema["Map Request Body Map<br/>(Binds string keys to raw JSON fields)"]
end
%% Socket Outbound
subgraph TransportBus["Outbound Network Buffer"]
StreamBody["Compiled Request Payload<br/>({ 'user': '9001', 'locale': 'en' })"]
end
%% Flows
VarCaller --> MapSchema
VarLang --> MapSchema

Custom Serialization parameters
1. Dynamic Attribute Body Maps
User interfaces configure clear key-value dictionary templates mapping active call keys directly into JSON parameters:
- Body Key:
user_phone-> Source Scope:session.CallerID - Body Key:
auth_code-> Source Scope:local.DtmfInput
2. Strict Transport Validation
If compiled bodies reference unknown parameters, mapping handlers intercept serialization threads instantly, flagging runtime exceptions to drop invalid API payloads automatically.
