Field validation for REST API

(0) Share

Posted on by Community Member

I have a custom entity for a solution, and I want to validate some fields (like required fields, regex for particular fields etc). Some of the fields were marked required during field creation, but those fileds are only got validated on CRM FORM not for REST API. I also tried out Custom Workflow by following this but that didn't work for me.

How can I do this for REST API?

Regards.

If you want to validate data as it is created via any means (Crm form, REST API etc), then you'll need to use either a synchronous plugin (which would throw an Exception if the validation fails), or a synchronous workflow (which would cancel the workflow if the validation fails)

Ensure that the custom workflow you have is 'a real time workflow'.

Else, it will be an async job.

For any server side validation, use real-time workflows or plugins.

And throw exception from the plugin code.

Hi,

Thanks for the reply I was being able to validate the field for REST API using real time workflows, but the response is not the same as I have set in the workflow. REST API is giving 500 when validation fails, and I wan that the response should be the message which has been set. I have attached the screenshot of workflow.

Thanks,
