REALTOR.ca DDF Lead API
The DDF Lead API is a single documented POST endpoint, /v1/Lead/CreateLead, on the same ddfapi.realtor.ca host as the DDF Web API. CREA requires it because REALTOR email addresses are deliberately excluded from the DDF Web API payload - "Real Estate Advertising Websites (REAW) are required to use the DDF lead API, as email addresses are not included in the DDF Web API". A syndicating site presents an "Email REALTOR" form to a consumer and posts the resulting lead through this endpoint rather than emailing the agent directly. It is described in the same public OpenAPI document as the rest of DDF and carries the same OAuth 2.0 client-credentials gate.
