How to update custom field values for Customer

arjanduijzer

I'm writing a sync between Lightspeed and another system. I want to store my external customerId in Lightspeed, using a custom field.

So, i've created a custom field for that, but unfortunately i cannot update custom fields using the API.

How can I accomplish this?

Thanks,

Arjan

Hi @arjanduijzer,

Thank you for contacting us.

You can do this by using the following payload in the customer endpoint.

PUT /Customer/{customer_id}.json

Payload:

{
	"CustomFieldValues": {
            "CustomFieldValue": {
                "customFieldID": "2",
                "type": "string",
                "value": "123456789"
            }
        }
}

I hope this helps.

Thanks for your answer. I've tested this from my code, but unfortunately it seems not working. The field value is not updated (not in result and not in Lightspeed)

This is my request, specially the field "WWMRelationId"

PUT https://api.lightspeedapp.com/API/Account/164996/Customer/1 HTTP/1.1

Accept: application/json

Authorization: Bearer *************

Cookie: __cfduid=************

Content-Type: application/json; charset=utf-8

Content-Length: 926

Host: api.lightspeedapp.com

{"customFieldValue":[{"customFieldValueID":294,"customFieldID":2,"name":"Nieuwsbrief","type":"boolean","value":"true"},{"customFieldValueID":1089,"customFieldID":7,"name":"Erkenningnummer","type":"string","value":"12345"},{"customFieldValueID":1090,"customFieldID":4,"name":"Jachtaktenummer","type":"integer","value":"1"},{"customFieldValueID":1091,"customFieldID":5,"name":"Verlofnummer","type":"integer","value":"2"},{"customFieldValueID":1092,"customFieldID":6,"name":"Verona Clientnummer","type":"integer","value":"3"},{"customFieldValueID":1093,"customFieldID":3,"name":"Erkenninghouder","type":"boolean","value":"true"},{"customFieldValueID":1124,"customFieldID":1,"name":"Membership","type":"single_choice","value":{"customFieldChoiceID":"1","name":"Standaard","value":"","canBeDeleted":"false","customFieldID":"1"}},{"customFieldValueID":1133,"customFieldID":8,"name":"WWMRelationId","type":"integer","value":"3964"}]}

For multiple custom fields:

'{"CustomFieldValues": {"CustomFieldValue": [{ "customFieldID": "13", "type": "integer", "value": "0"}, {"customFieldID": "8", "type": "boolean", "value": "false"}]}}'
