Call a Service Action


You can call actions associated with a service from Realm Functions, including incoming webhooks and triggers, or directly from a connected client application. Each service action is available as a method on its respective service client.


You must configure a service rule that enables an action before you can call it.

The examples in this section demonstrate calling the post() action from the HTTP Service. Each service action follows a similar pattern but has distinct parameters. For details on the parameters and usage of a specific action, refer to that action’s reference page.

Call from a Function

To call a service action from a function:

  1. Instantiate a service client from application context using the global variable.
  2. Call the method associated with the action.
const http ="myHttpService");{
    "url": "",
    "headers": { "Content-Type": ["application/json"] },
    "body": { "msg": "Hello from a service action!" }
  .then(() => "Successfully sent the post request!")
