Use the List Deal Stages endpoint to retrieve information about every deal stage that is available in your team's Apollo account.
The id value for each deal stage can be used to set the stage when creating a deal or updating a deal via the Apollo API.
This feature is not accessible to Apollo users on free plans.
This endpoint also requires a master API key. If you attempt to call the endpoint without a master key, you will receive a 403 response. Refer to Create API Keys to learn how to create a master API key.
