Binding support

This component supports both input and output binding interfaces.

This component supports output binding with the following operations:

  • create

Specifying a TTL per message

Time to live can be defined on queue level (as illustrated above) or at the message level. The value defined at message level overwrites any value set at queue level.

To set time to live at message level use the metadata section in the request body during the binding invocation.

The field name is ttlInSeconds.

  1. curl -X POST http://localhost:3500/v1.0/bindings/myServiceBusQueue \
  2. -H "Content-Type: application/json" \
  3. -d '{
  4. "data": {
  5. "message": "Hi"
  6. },
  7. "metadata": {
  8. "ttlInSeconds": "60"
