Posted on by BexNexus

I created GET and POST requests. And now I am trying to use PATCH request to update the purchase invoice data via Postman and getting the following error :

{
    "error": {
        "code": "BadRequest_InvalidToken",
        "message": "Could not validate the client concurrency token required by the service. Please provide a valid token in the client request.  CorrelationId:  f680dd3c-3b23-4bd4-b4a0-f650dba743c5."
    }
}

Body (raw, JSON):

PATCH request line:
api.businesscentral.dynamics.com/.../purchaseOrders({id})

I do not understand what I am doing wrong.

Any Idea?

Thank you very much ! Now it worked.

I erroneously put the keys to Params section, not the Headers.
