Creating record returns 406 INVALID_ACCEPT_HEADER

First of all, is the Record topic of the docs missing an Attributes section? The other topics all seem to start with Attributes, but nothing for records.

I am sending an HTTP POST to to create a new record but regardless of what I try, the only result ever returned is a 406. I issued a GET request against the same model, copied and pasted the attributes back, minus the created one and still receive a 406. Here is my request with the apikey obfuscated.

X-Api-Version: 3
Authorization: Bearer xxx
Accept: application/json
Content-Type: application/json

  "data": {
    "type": "item",
    "attributes": {
      "first_name": "Troy",
      "last_name": "Forster",
      "email_address": "",
      "phone_number": "4166174921",
      "salesforce": "",
      "results": [
    "meta": {},
    "relationships": {
      "item_type": {
        "data": {
          "id": "199010",
          "type": "item_type"

Everything looks good there.

Can you please share some code that I can run to reproduce your call? Even just a curl call?


I had a blank line between the request and the headers in my VSCode that I cleaned up when I posted the sample above. The RESTClient extension I use, as a quick-n-dirty convenience over PostMan, sees the line break as ending the request AND headers. Everything that follows is interpreted as the body.

Remove the line break and now Iā€™m getting back a clean response from Dato.

EBKAC - sorry
