    ## Card Store Integration


    Merchants using ME Payment Gateway Store Card tokenization can send Card
    Store ID instead of full card numbers.


    **Benefits:**

    - No card number transmission (send tokens only)

    - Automatic token updates

    - Enhanced security

    - Simplified PCI compliance


    **Workflow:**

    1. Store card via gateway API → receive Card Store ID (32 chars)

    2. Use D2 record type with Card Store ID in AUS request

    3. ME automatically retrieves card data for update check

    4. Associations check for updates

    5. Token automatically updated with new card data

    6. Continue using same Card Store ID (now represents updated card)


    **Response Format:**

    - New card numbers returned truncated: first6+xxxxxx+last4

    - Example: 480500xxxxxx0058

    - Full data automatically updated in token storage


    **Testing Note:**

    Multiple tests with values returning new card# need new Card ID created each
    time.

  conversion-notes: >
    **Issues identified and corrected in this conversion:**


    1. **CRITICAL - Duplicate userPass property (Lines 92-100 in original):**
    The original YAML
       had userPass defined twice in the upload request schema. This is invalid YAML/OpenAPI.
       Fixed by removing the duplicate definition.

    2. **Missing reqfName_n in status example:** The status inquiry response
    example was
       missing the reqfName_n parameter that is documented in the PDF (Page 11).
       Added to examples.

    3. **Response detail record character count:** Original stated "126
    characters" but
       correct calculation per PDF Page 7-8 is 124 characters
       (2+4+32+4+4+32+4+8+2+32=124). Corrected.

    4. **Missing maxLength for statusFilter:** PDF specifies 16 character max
    length.
       Added maxLength: 16 to the parameter schema.

    5. **Missing response schemas:** Added proper schemas (UploadResponse,
    StatusResponse,
       ErrorResponse) to document the URL-encoded response parameters per PDF.

    6. **Download response ambiguity:** Clarified that download returns either
    file data
       (with Content-Disposition header) OR error response, and client must detect which.

    **Note on PDF Page 12:** The source PDF has a heading "Upload file response
    parameters"

    in the Download section, which appears to be a documentation error in the
    original.

    The table content is correct for download error responses.
