Update Tridy ============ A Tridy represents a unique identifier and can store information about the identified object. This tutorial describes how this information can be updated if it changes. In the "Getting Started" tutorial we created a Tridy for a sneaker with these properties: .. code-block:: JSON { "ean": "12345678", "productName": "White, fancy Sneaker", "price": "123,32€" } Authentication ^^^^^^^^^^^^^^ To update data via the API we need to authenticate using the Narravero API token we received. To try the API, we can do this on the `Authentication `_ page: .. image:: images/openapi-authenticate.png After we copied the token into the text field and clicked "Set", the authentication is stored. Update ^^^^^^ If we have a price drop for our sneaker, we need to update the information to look like this with a ``price`` changed to "98,32€": .. code-block:: JSON { "ean": "12345678", "productName": "White, fancy Sneaker", "price": "98,32€" } We can use the API as described here: `Update Tridy payload `_ to update it. Since only the field ``price`` changed, we can use this endpoint to just update the price, using this body to the request: .. code-block:: JSON { "price": "98,32€" } .. image:: images/openapi-update.png
