# External identifiers

### **External Identifiers (`remote_id`)**

To facilitate integration between your system and Dashdoc, most API resources support an optional `remote_id` field.

You can set this field to your own internal identifier when creating or updating a resource. This allows you to:

* Link Dashdoc resources with your internal objects.
* Avoid storing a mapping table of Dashdoc IDs on your side.

Once set, you can also use `remote_id` to retrieve or update objects in a consistent way.

{% hint style="warning" %}
**Note:** Not all resources support `remote_id`. Please refer to the [resource reference](broken://pages/g8EX2Fs7v9kSqBj8ALFh) for a detailed list.
{% endhint %}
