# Multi-step completion in a single response A single response may indicate that **more than one step is already completed**. * A step being marked as already completed means that, **for the current checkout state and the current basket state**, no additional input is required to proceed past that step. * This evaluation is **state-based**, not request-based. Client implementations must not assume a strict "one request = one step completion" relationship. * If the basket content changes (for example: quantity changes, item added/removed), previously completed steps **may no longer be considered completed**. In that case, the response returns the up-to-date checkout state and indicates the appropriate step to continue. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://apidocs.akinon.com/commerce-openapis/checkout/checkout-overview/multi-step-completion-in-a-single-response.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
