Versioning (Interaction Control API)

Specify the version of the Interaction Control API in the Accept header of each request. The current version is v5.

Format	Value

Format	Value
Pattern	`Accept: application/vnd.newvoicemedia.v{n}+json`
Example (v5)	`Accept: application/vnd.newvoicemedia.v5+json`

If the Accept header is missing from your request, you will receive a 400 Bad Request error.

How versioning works

When a new version of any endpoint is released, the whole API is versioned. For example, if a new version v{n} is released for a given endpoint, the new version v{n} is supported across the entire API.

Same data format across versions

Some endpoints return the same data format across multiple versions.
