Option 1objectNeonFunctionDeployment

created_atstringrequired

environmentarray of string

The NAMES of the deployment's environment variables, sorted. Values are encrypted at rest and are never returned — they are write-only. To change a value, deploy the variable with the new value; to remove a variable, deploy it with an empty value.

Show child attributes

errorstring

Human-readable reason the deployment build failed. Present only when `status` is `failed`.

idinteger · int32required

The deployment id, which is the platform version number (monotonic per function).

memory_mibinteger · int32required

runtimestringrequired

statusstringrequired

Build lifecycle status of the deployment.

one of "pending", "building", "completed", "failed"

created_atstringrequired

current_deploymentvalue

The most recent deployment, regardless of build status. It may still be building or it may have failed. Omitted until the first deployment is created.

Option 1: NeonFunctionDeployment ↑

idstringrequired

Opaque, stable function identifier.

invocation_urlstringrequired

URL at which the function is invoked. The host carries `<branch_id>-<slug>` as its first DNS label under a Neon-managed functions domain, and the URL ends with a trailing slash so paths concatenate onto it. Empty string when the function has no servable invoke host (e.g. a deployment without an invocation front-door).

namestringrequired

Free-form display name.

slugstringrequired

Branch-unique, lowercase DNS-label. Forms the invocation URL's host together with the branch id. Immutable.

defaultGeneral Error. The request may or may not be safe to retry, depending on the HTTP method, response status code, and whether a response was received. - If no response is returned from the API, a network error or timeout likely occurred. - In some cases, the request may have reached the server and been successfully processed, but the response failed to reach the client. As a result, retrying non-idempotent requests can lead to unintended results. The following HTTP methods are considered non-idempotent: `POST`, `PATCH`, `DELETE`, and `PUT`. Retrying these methods is generally **not safe**. The following methods are considered idempotent: `GET`, `HEAD`, and `OPTIONS`. Retrying these methods is **safe** in the event of a network error or timeout. Any request that returns a `503 Service Unavailable` response is always safe to retry. Any request that returns a `423 Locked` response is safe to retry. `423 Locked` indicates that the resource is temporarily locked, for example, due to another operation in progress. application/json
