API changes: removing number_of_contracts field
Dear developers,
We are going to remove the number_of_contracts (numeric type) field, which is being returned from our Price Proposal and Price Proposal: Open Contracts API calls for Vanilla contracts. We already have added another field named: dispaly_number_of_contracts (string type) to these API calls as a replacement. This will be released in the week starting July 10.

The only change in the API response for the two API calls is the removal of the number_of_contracts field in the response.
