Deprecaton of greennessForecast GraphQL query.

What is changing?

The greennessForecast query, which previously provided information about the predicted greenness of energy available throughout the day, is being deprecated.
This data will now be available through a new API located at api.backend.octopus.energy/v1/graphql.

Please note:

• The API schema has changed.
• The equivalent GraphQL field is now called greenerNightsForecast.
• The new query is not identical to the old one - field names have been updated.

Timeline

The greennessForecast query will be removed on 13 January 2026.

What You Need to Do

• Stop using the greennessForecast query.
• Optionally - update your integration to use the greenerNightsForecast field at api.backend.octopus.energy/v1/graphql.
• Review the new schema carefully to adjust for the changed field names and structure.
