We are extending the V1 API shutdown deadline to
March 31st, 2020 May 31st, 2020. Migrate to the V2 API as described here.
If you use Dialogflow exclusively for Actions on Google, you don't need to migrate your agent to the V2 API. However, note the following changes:
- The Dialogflow simulator will show responses in the V2 format and the "Copy curl" button will generate requests in the V2 format. This should have no impact on the functionality of the Actions on Google simulator.
- You will no longer be able to call API methods for the V1 intents and entities resources. You will still be able to modify your agent using the Dialogflow Console.
October 17, 2019
When calling the API to provide an intent priority value, the behavior has changed to the following:
- If the supplied value is unspecified or 0, the service
translates the value to 500,000, which corresponds to the
Normalpriority in the console.
- If the supplied value is negative, the intent is ignored in runtime detect intent requests.
Prior to this change, a value of 0 was stored as-is by the service. Any agents created before this change may still have intent priority values of 0. For runtime detect intent requests, a value of 0 is treated as -1, and the intent is ignored.
