Specifying entity IDs in trxs sent to the single transaction ingestion API

Going forward, the single transaction ingestion API will no longer accept transactions that include both the entity's by_external_id and the embedded entity's external_id. For example, the following construction is no longer allowed:

{ 
  ...
  "receiver": {
    "by_external_id": "B7FA3237-72F6-49B3-9BA9-D35AC74F54EC",
    "external_entity_type": "business",
    "business": {
      ...
      "external_id": "3CB6FBC9-7106-42C2-988B-C6F363E58381",
      ...
    }
  },
  ...
}

In such cases the API will respond with:

"Only provide an entity by_external_id value or an embedded entity external_id value, not both."

Please only specify the entity via the by_external_id, e.g.:

{
  ...
  "receiver": {
    "by_external_id": "B7FA3237-72F6-49B3-9BA9-D35AC74F54EC"
  },
  ...
}

Or via the embedded entity object, e.g.:

{
  ...
  "receiver": {
    "external_entity_type": "business",
    "business": {
      ...
      "external_id": "3CB6FBC9-7106-42C2-988B-C6F363E58381",
      ...
    }
  },
  ...
}
