lam.asyncExecute

Learn more about the asyncExecute keyword

Functionality

The asyncExecute keyword executes each specified workflow in parallel. Unlike lam.execute, this keyword runs workflows asynchronously and does not block the current workflow's execution.

Invocation

Data transformation must output:

{
  "lam.asyncExecute": [
    {
      "lam.workflowId": 39,
      "lam.payload": { /* payload data */ }
    }
  ]
}

Key	Description	Type
asyncExecute	The workflows to execute with a payload	Array<{ workflowId, payload }>
workflowId	The workflow ID to invoke asynchronously	Integer
payload	The payload to pass to the workflow	Object

Examples

(payload) => {
  const { input } = payload;
  const { Recipient, PackagesInfo } = input;
  
  const packagePayloads = PackagesInfo.Packages.map(pkg => ({
    "lam.workflowId": 39,
    "lam.payload": {
      address_1: Recipient.Address1,
      address_2: Recipient.Address2,
      EXT_FIELD_first_name: Recipient.Firstname,
      EXT_FIELD_last_name: Recipient.Name,
      EXT_FIELD_email: Recipient.Email,
      EXT_FIELD_phone: Recipient.Tel,
      EXT_FIELD_weight: pkg.Weight.Value,
      custom_user_fields: [
        { order_custom_field_id: 1852 }
      ],
      address_city: Recipient.City,
      address_state_id: Recipient.CountryStateCode,
      address_country_id: Recipient.CountryCode,
      address_zip: Recipient.PostalCode,
      tracking_number: pkg.PreAssignTrackingNumber.TrackingNumber
    }
  }));

  return {
    "lam.asyncExecute": packagePayloads
  };
}

In this example we map an array of packages to the asyncExecute keyword. Laminar will then invoke workflow 39 with each individual payload in parallel.
