Issue PATCHing Company Customer custom field

[Ashishs]

Hi,

I am trying to update custom field with id 156 on Company Customer table:

API Endpoint - /api/v1.0/companies/0/customers/__CUSTOMER_ID__/customFields/156

Request Body:
=============
{
"Value": "2025-08-31"
}
=============

I am getting 422 Unprocessable Entry with following response body:
=============
{
"errors": [
{
"path": null,
"message": "No data to be updated for customer custom field.",
"value": "156"
}
]
}
=============

I'm using Postman for testing.

Please advise.

Hi,

Can you check if your header includes the Content-Type: application/json or make sure the body type is json.

[Ashishs]

Here is the command:

curl --location --request PATCH 'https://__COMPANY_NAME__.simprosuite.com/api/v1.0/companies/0/customers/21978/customFields/156' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer __TOKEN__' \
--data '{
"Value": "2025-08-31"
}'

Here 156 is the custom field ID that I want to update.

Response body:

{
"errors": [
{
"path": null,
"message": "No data to be updated for customer custom field.",
"value": "156"
}
]
}

I need to resolve this to finish a project. Please advise as it is a blocker

Hi Ashish,
Your request body looks correct and I have copied it directly into my postman for testing successfully.

The error indicates that something is missing from the request body. Such as a missing bracket, or a comma following the value if there is only one value in the JSON being sent. Or if it was set as text format instead of JSON.

Code: Select all

{
    "Value": "2025-08-31"
}

This body should work fine for custom fields of type text and date.

As we are unable to replicate this i suggest you create a case with our helpdesk who can try to reproduce this in a copy of your build. Please include your Simpro build name and the id's of the customers and customfields for testing.

I figured out. There is nothing wrong with the request body. But the request header was missing "Content-Length" which apparently is required for this PATCH operation.
