Update template

PUT /api/templates/{id}

Update any supplied fields. Read the existing template before changing it. payload and project are aliases; never supply both.

Authentication

Option 1: x-api-key: YOUR_API_KEY (header). API key for authentication. Create one in your dashboard.
Option 2: Authorization: Bearer YOUR_ACCESS_TOKEN. Dashboard JWT in Authorization: Bearer <token>, only on operations that explicitly list this scheme. Prefer x-api-key for REST integrations. OAuth for hosted MCP is a separate connection at https://mcp.zvid.io/mcp.

Create API keys at app.zvid.io/api-keys. Keep credentials on your server.

Parameters

Parameter	Location	Type	Required	Description and constraints
`id`	path	string	Yes	Pattern: `^tpl_[A-Za-z0-9]{20}$`.

Request

The shell examples read credentials from ZVID_API_KEY (or ZVID_ACCESS_TOKEN for Bearer authentication). Set that variable in your environment. Replace sample project, template, job, and asset identifiers with values from your own account.

A request body is required.

application/json

Minimum properties: 1. Unknown properties are rejected.

Field	Type	Required	Description and constraints
`body.name`	string	No	Minimum length: `1`. Maximum length: `255`.

`body.payload`	RenderPayload	No
`body.project`	RenderPayload	No	Compatibility alias for payload. Supply exactly one.

Additional JSON Schema constraints:

{
  "not": {
    "required": [
      "payload",
