## Modifications to Inquiry Process 

### Summary

- POS does not send Inquiries for local declines. (Simplify handles all required processing).

- For local approvals, the Inquiry request should include the SAF token (API 5073) from the original transaction response. 

- Since Simplify handles expiration of SAF transactions, the Inquiry response may indicate that the transaction has expired (either the card has expired, or the transaction is older that the configured number of days to keep pending).

- If the Inquiry response indicates that the transaction has been forwarded approved, the POS can obtain the Fusebox token from API 5035.  

  **Note**: For any transactions from the POS that require a token from a locally approved transaction, the POS should send an Inquiry for the original transaction and wait until the true token is returned from Fusebox (i.e. until the transaction has been forwarded and approved). 

- The following subsections provide additional details on the modified Inquiry process. 

### Scope

If On-Device SAF is enabled, the POS should periodically send an Inquiry request to Simplify for the following transactions, until resolved:

- Transactions that did not receive a response from Simplify.

- Transactions locally approved by Simplify (SAF token sent to POS).

**Note**: There is no need for the POS to send an Inquiry on a locally declined transaction.  Simplify is responsible for reversing if the original transaction was approved by the host.  

### Timing

- Inquiries can be sent whenever the lane is idle, and the store is not busy.

- Inquiries can be sent as part of the end of day process.

### Processing Algorithm for Local Approvals

- POS receives a local approval with a SAF Token on a Credit transaction (Sale, Refund or Void).

- POS sends an Inquiry with the SAF Token when the PIN Pad is not in use by a customer.

- POS checks the response codes to determine whether the transaction has been resolved, i.e. forwarded (host) approved or declined, or expired (declined by Simplify).  

    - If the transaction was host approved, the POS should parse the Fusebox data returned in API 5074 (22 token type) to retrieve the PAN token.

Note: An Inquiry with a SAF token from the POS concerning a locally approved transaction will not be sent to Fusebox. Simplify will instead return the most recent result contained in the database record identified by the SAF Token.

## Inquiry Message Fields

For additional information on Inquiry Message fields, see the *Fusebox Integration Guide* :magic-link[Transaction Inquiry (22)]{id="/products/fusebox/v1/transaction-inquiry-md"}


### Request

- No response received – Standard Inquiry request fields (based on original request).

- Local approvals – Standard Inquiry request fields plus SAF Token from original response (API 5073).  

**Note**: For all Inquiries, the *original* transaction date and time must be sent in API 0013 and 0014.

### Response

- Non-SAF transactions (not in SAF database) – Standard Inquiry response fields.  

- SAF transactions – Standard Inquiry response plus the following API’s:

    - 5073 – SAF Token

    - 5074 – Database  fields and Fusebox record (22 token type)

    - 5075 – Total SAF Local Approved Pending Amt : Maximum total amount of pending local approvals (configured)

    - 5076 – Total SAF Local Approved Pending record count : Total Database record count : Maximum number of allowed database records (configured) : Free Flash Data bytes : Free RAM bytes

    - 5077 – Total SAF Local Approved Pending record count : Total SAF Local Declined Pending record count

Note: For a POS Inquiry request on a “no response” transaction, Simplify will determine whether it was a SAF transaction.  If yes, it will add API 5073 through 5077 to the Inquiry response.   

## Message Flow for Local Approvals 

The following table and bulleted list show the message flow for a locally approved Sale transaction:

::image{id="/content/dam/developer-portal-solutions/en-us/elavon/media/images/products/simplify/localapprovalmessageflows.png"   alt="Offline Message Flow. See text just below."}


-   Original Transaction		
    -   POS sends Sale Request.  
    -   Simplify sends Sale Request to Fusebox and times out waiting for a response.
    -   Simplify locally approves the transaction by Stand-in and writes transaction to SAF database with SAF token.
    -   Simplify sends a Stand-in Sale Response including the SAF token.
    -   POS stores SAF token.

-   SAF Processing			
    -   Simplify sends SAF (Forward) Request.
        -   If it receives a host response (forwarded approval or decline) , it updates the SAF database.
-   Inquiry Processing (can be sent through Simplify or directly to Fusebox)
    -   POS sends Inquiry Request including SAF token
    -   If sent to Simplify, Simplify looks up transaction using SAF token.
        -   If resolved, Simplify writes transaction record to Inquiry response and send response. 
        -   Else response returns status as Pending. POS resends Inquiry after configured interval.
