Base URL: https://api.sevalla.com/v3. Authenticate with an API key in the Authorization header as a Bearer token. > The OpenAPI spec is at https://api.sevalla.com/v3/openapi.json. Concepts and dashboard guides are at https://docs.sevalla.com (index: https://docs.sevalla.com/llms.txt). > To act on a Sevalla account from an AI agent, prefer the Sevalla MCP server (https://mcp.sevalla.com/mcp, see https://docs.sevalla.com/ai-agents/overview.md) or the Sevalla CLI (https://api-docs.sevalla.com/v3/cli.md). # Create external database backup > Create a manual external backup of a database. The database is dumped and the file is uploaded to the backup target bucket asynchronously; the backup appears in the external backup list once the upload completes. Requires at least one backup target attached to the database, otherwise a 400 is returned. A target can hold at most 5 manual backups. The database and its backups must be in a ready state. Databases that do not support external backups return a 400. ## OpenAPI ````yaml https://api.sevalla.com/v3/openapi.json post /databases/{id}/external-backups openapi: 3.1.0 info: title: Sevalla API docs version: 1.0.0 servers: - url: https://api.sevalla.com/v3 security: - bearerAuth: [] paths: /databases/{id}/external-backups: post: tags: - Databases summary: Create external database backup description: >- Create a manual external backup of a database.
