Versioning

The version is the first segment of every path: /v1/leads. Within a version, LeadUp only makes changes that don't break a correct client.

Safe changes

These happen without notice, so write your client to accept them:

• New endpoints.
• New optional fields in a request, and new fields in a response.
• New values in a response enum, such as a new stage.
• New error codes.

Breaking changes

Removing or renaming a field, endpoint or error code, changing a field's type or meaning, making an optional field required, tightening validation or changing a status code all ship as a new version beside the old one. The old version keeps working as it did.
