Create a people batch

POST /v1/companies/#/people_batches creates a people batch and returns its .

Scope: people_batches:write

Request details

The body of the request is a JSON object that must contain:

• A unique UUID idempotency_key

  This idempotency_key must be generated on the caller’s side to ensure idempotency of requests. If the idempotency_key is not unique for the given company, the upload will result in a 409 error.

  The idempotency_key is the caller’s unique identifier for a batch request - it is required to ensure that each batch is only created once. Once a batch is created the response will show the batch_uuid.

• A batch_action

• Within the batch, there must be an entity_type, e.g. “employee”

• Each person object must contain an external_id from your system for create actions.

  • The external_id will not be persisted.

For any other optional attributes, see the API reference or the detailed input section.

Response details

The batch_uuid, Gusto’s unique identifier for a batch request, is returned. This is required to later fetch the batch status.

bash

{
  "batch_uuid": "9f879a17-7166-4b5e-9266-334a642898c6",
}

• 201 Created: Batch accepted and we return the batch_uuid
• 409 Conflict: When the same idempotency_key is used more than once
• 422 Unprocessable Entity: When there is an issue with the batch data itself, e.g. JSON validation errors

Examples

Minimum / mandatory inputs for each Employee

bash

{
  "idempotency_key": "bcfc9744-0ab3-4ef3-ab0d-e728255d659c",
  "batch_action" : "create",
  "batch": [
    {
      "entity_type": "employee",
      "person": {
        "external_id": "employee-abc-123",
        "first_name": "Alice",
        "last_name": "Smith"
      }
    }
  ]
}

external_id

As outlined in the Request section of this guide, the external_id is your unique identifier for a person—this will be your employee identifier.

The external_id is used only ephemerally while the batch is processing, and then returned in the batch results alongside the person’s employee_uuid. You must associate the Gusto employee_uuid with your external_idin order to reference the person in later API calls.

Optional inputs

Only the minimum person data is mandatory—each of these sections is optional:

• home address , optionally with "work_from_home" status

  • either home address or work location, or both can be provided

  • when home address with "work_from_home" is given, we internally create a new work location, and passing-in a work address is not permitted.

• work address (aka company location; needs to be created via regular API calls)

  • this is taking the UUID of an existing work location

• job details

• compensation

• Bank Accounts and Paycheck Distributions for Direct Deposit.

  • ordered list of bank accounts with splits (all-in-one)

• Department

  • department_uuid
