Template Hook
Populate template message variables dynamically
Template hook will likely be your best buddie in your conversation flows.
The engine uses the {{ mustache }} templating engine (like Python Jinja) to populate the dynamic variables.
It is used to dynamically create a conversation message body.
JAWCE also supports RESTFul based hooks.
Only JAWCE supports both reflective and restful based hooks
"PAYMENT_ORDER":
type: text
template: "rest:/gpay/order"
message:
- "Thank you {{ user }}."
- ""
- "Your Avon order has been processed with reference: {{ reference }}"
- "for {{ currency }} {{ amount }}"
routes:
"re:.*": "HOME_MENU"
The tagged template hook should return a render-payload matching each variable in the defined template
@RestController
class OrderController {
@PostMapping("/order")
public Object orderDetailsTemplate(@RequestBody HookArgsRest args) {
// .. process business logic
// .. get order details from db or a service
// .. return a render-payload of Map matching template variables
args.setTemplateDynamicBody(
new TemplateDynamicBody(
null,
null,
Map.of(
"user", args.getChannelUser().name(),
"reference", "order-#1234",
"currency", "USD",
"amount", 20.50
)
));
return args;
}
}
