Hi @expertoswp
This isn’t an API feature but one that can be found in the web interface too. The only restriction on clients is you can only have 1 with the same name. For example, “Company A Ltd” and “Company A Ltd” would be considered the same, but “Company A Ltd” and “Company A Limited” wouldn’t.
All errors are returned as JSON. For example, a duplicate client would return:
{
"Errors": {
"Error": [
"A client record with this name already exists"
]
}
}
Hope this helps.
