How to update custom field values for Customer

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?

    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


    	"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 HTTP/1.1

    Accept: application/json

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

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

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

    Content-Length: 926


    {"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"}]}}'

    Hi there,

    I'm trying to do something similar, but the api throws this:


    "error": {

    "code": 403,

    "method": "UPDATE",

    "request": "/nl/customers/103060641.json",

    "message": "The server understood the request, but is refusing to fulfill it."



    Any advice?

    Do you API credentials have scope permissions to modify customers? What does your request body look like?

    Hi Gregarcian,

    Didn't look at that, checked it and it seems i only have read permissions :-/
