Configuration
7 fields, none required. A dotted path is a nested object and name[] an array of objects — the editor renders the same tree.
| Field | Type | Required | Default | Constraints | Example |
|---|---|---|---|---|---|
template_id MSG91 template to use; overrides the default template set on the connection. | string | No | — | — | 65f1b2c3d4e5f60718293a4b |
mobiles One recipient number, or several separated by commas, in international format with the country code. | string | No | — | — | 919000000000 |
variables Template variables applied to every recipient; keys are case-sensitive and match the ##var## names in the template. | object | No | — | — | {"VAR1":"Acme","VAR2":"1234"} |
recipients Full recipient rows when each number needs its own variables; each entry needs a 'mobiles' key. Overrides the fields above. | array | No | — | array of object | [{"VAR1":"Acme","mobiles":"919000000000"}] |
short_url Rewrite links in the message as MSG91 short URLs so clicks are tracked. | boolean | No | — | — | — |
short_url_expiry How long a tracked short URL stays valid, in seconds. | number | No | — | ≥ 1 | — |
real_time_response Ask MSG91 to answer with the uncached submission result so most API errors surface on this call instead of later. | boolean | No | — | — | — |
- At least one of mobiles, recipients must be set.

In a technical demo we add the MSG91 connection, drop the node on the canvas and let Workflow Health pre-flight it before the first real run.
