Unlink an external product from a product. DELETE /products/{productId}/external-products/{externalProductId}.
AI agents call unlink_external_product to permanently remove resources in Rebillia MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool uses a DELETE HTTP method to remove the association between an external product and a product. This is an irreversible unlinking/deletion operation that cannot be undone, making it Destructive. The blast radius is high because removing external product links in a subscription billing system could break product integrations across e-commerce platforms like BigCommerce, WooCommerce, or Shopify.
