GraphQL: How to Create an Entity Customer with an Account / AccountId Automatically?

V5 Question
1

Hi everyone,

I’m working on an integration between our Reservation Service and SambaPOS.

The expected flow is:

  1. Customer makes a reservation.

  2. Customer pays a deposit (DP) in our Reservation Service.

  3. Reservation Service creates the customer in SambaPOS.

  4. SambaPOS creates an Account for that customer.

  5. We post the deposit amount into the customer’s account.

Creating the customer through GraphQL works:

mutation {
  addEntity(entity: {
    entityType: "Customers",
    name: "Ceem",
    customData: [
      { name: "Phone", value: "1234567890" },
      { name: "Tanggal DP", value: "08/21/2026 12:00 am" },
      { name: "Booking Date & Time", value: "08/21/2026 12:00 am" }
    ]
  }) {
    id
    accountId
    type
    name
  }
}

The entity is successfully created, but accountId is 0.

I checked the GraphQL schema for EntityInputType and it only contains:

entityType
name
customData

There is no accountId or createAccount field.

I also checked all available mutations through introspection and I couldn’t find any createAccount / addAccount mutation.

What I tried with Automation

I created a SambaPOS script that calls:

api.Entity("Ceem").CreateAccount();

When I run/test this script directly from SambaPOS, it works correctly and the account is created.

I then created an Automation Rule:

Event:
Automation Command Executed

Automation Command:
Create Customer Account

Action:
Execute Script

If I trigger the rule from inside SambaPOS, it also works.

However, when I trigger the Automation Command through GraphQL:

mutation {
  executeAutomationCommand(
    name: "Create Customer Account"
    terminal: "Kasir"
    department: "DINE IN"
    user: "Administrator"
    ticketType: "Ticket"
  )
}

the mutation succeeds, but the expected account creation does not happen.

GraphQL Parameters Issue

I also tried passing the customer name through parameters.

For example:

parameters: [
  { name: "CustomerName", value: "Ceem" }
]

but SambaPOS returns:

System.MissingMethodException:
No parameterless constructor defined for this object.

GraphQL.ObjectExtensions.ToObject(...)

I get the same error when trying notifyEvent with parameters.

Without parameters, executeAutomationCommand works.

I also tried notifyEvent with AutomationCommandExecuted, but using parameters results in the same MissingMethodException.

What I’m trying to achieve

Ultimately I want this to happen without any manual action in SambaPOS:

Reservation Service
       |
       | Customer Paid Deposit
       v
SambaPOS GraphQL
       |
       +--> Create Customer Entity
       |
       +--> Create Customer Account
       |
       +--> Post Deposit to Customer Account

Currently the blocking part is:

Entity created successfully
        ↓
accountId = 0
        ↓
How can I create/link the account automatically?

Is there a supported way through GraphQL to:

  1. Create an Entity and automatically create its Account?

  2. Call something equivalent to api.Entity(name).CreateAccount()?

  3. Trigger an Automation Rule from GraphQL in the same context as triggering it from SambaPOS?

  4. Or is there another recommended approach for posting customer deposits from an external application?

The important requirement is that this needs to run server-side automatically, without someone having to open SambaPOS and manually create the account or enter the deposit.

Any guidance on the recommended SambaPOS approach would be greatly appreciated.
