## Authorizations

- `Authorization` (header, string, required) — Bearer authentication header of the form `Bearer <token>`.

## Headers

- `X-Pinecone-Api-Version` (header, string, required) — Required date-based version header

## Body

- `principal_type` (body, string, required) — The kind of principal that receives permissions from a role binding. Possible values: `user`, `service_account`, `api_key`, `invite`.
- `principal_id` (body, string, required) — Principal ID. Format depends on `principal_type`.
- `resource_type` (body, string, required) — The kind of resource scope a role binding applies to. Possible values: `organization`, `project`.
- `resource_id` (body, string) — Project UUID. Required when `resource_type` is `project`; omit for `organization` scope.
- `role` (body, string, required) — A role assigned to a principal at a resource scope.

## Response

- `200` — Role binding created.
- `400` — Bad request. The request body included invalid request parameters.
- `401` — Unauthorized. Possible causes: Invalid API key.
- `403` — Forbidden
- `404` — Not found
- `409` — Conflict. The request conflicts with the persisted state of the resource. Common causes include invariant violations (e.g., removing the last `OrgOwner`), lifecycle-state mismatches (e.g., resending an invite that is not pending), and constraint violations checked against persisted data.
- `500` — Internal server error.
- `4XX` — Unexpected error on request.
