Pseudo Code for Processing API Transactions


Overview


This pseudo code represents the logic to process a list of API transactions (apiTransactionList) by evaluating each transaction based on its API name. It updates a summary record map and manages responses accordingly. 


Data Structures


    

  • apiTransactionList: List of API Transactions to process.
    • 

  • inputMap: Input parameters provided for transaction processing.
    • 

  • transaction_record: List holding transaction summaries.
    • 

  • bfTransSummToUpdate: Map to track transactions that need updating.
    • 



Function Definition


Define the function to process API transactions:


Function processAPITransactions(apiTransactionList, inputMap, transaction_record) 
    Initialize bfTransSummToUpdate as empty map
    Initialize wrapperClass as new WrapperClassForProcessAPITransactions()

    For each apiTrx in apiTransactionList do
        Initialize addrssMatch to NULL

        If apiTrx.API_Name equals SERVICEADDDRESSVALIDATIONS then
            Call function apiNameIsServiceAddressValidations(apiTrx, addrssMatch, bfTransSummToUpdate)
            Update apiTrx, addrssMatch, and bfTransSummToUpdate with return values

        Else If apiTrx.API_Name equals 'AddressBusinessService' or 'SubmitByGeoAddressId' then
            addrssMatch = handleAddressBusinessService(apiTrx, addrssMatch)
            If apiTrx.API_Name equals 'AddressBusinessService' then
                If apiTrx.API_Response_JSON is not NULL 
                    And captureCompanyOnwerIdBMFlow(apiTrx.API_Response_JSON) is not NULL then
                    updateCompanyOwner(bfTransSummToUpdate, apiTrx)

        Else If apiTrx.API_Name equals 'serviceAddresses' AND apiTrx.API_Status_Code equals '200' then
            Call function apiNameIsServiceAddresses(apiTrx, addrssMatch, bfTransSummToUpdate)
            Update apiTrx, addrssMatch, and bfTransSummToUpdate with return values

        Else If apiTrx.API_Name equals 'performUnifiedQual' then
            Call function apiNameIsPerformUnifiedQual(apiTrx, addrssMatch, bfTransSummToUpdate)
            Update apiTrx, addrssMatch, and bfTransSummToUpdate with return values

        Else If apiTrx.API_Name equals 'FindAvailableServicesV4' then
            Call function apiNameIsFindAvailableServicesV4(apiTrx, addrssMatch, bfTransSummToUpdate)
            Update apiTrx, addrssMatch, and bfTransSummToUpdate with return values

        Else If apiTrx.API_Name equals 'GetOffers' then
            If apiTrx.Buyflow_Transaction_Summary_ID is not NULL 
                AND apiTrx.API_Response_JSON is valid JSON then
                Call function apiNameIsGetOffers(apiTrx, bfTransSummToUpdate)
                Update apiTrx and bfTransSummToUpdate with return values

        Else If apiTrx.API_Name equals 'BIWF_GetOffers' or 'BIWF_GetOffers_SFCC' then
            Call function apiNameIsBIWFGetOffers(apiTrx, bfTransSummToUpdate)
            Update apiTrx and bfTransSummToUpdate with return values

        Else If apiTrx.API_Name equals 'serviceAddressesValidationsO2' or 'O2ServiceAddresses' then
            Try 
                addrssMatch = handleO2ServiceValidationResponse(apiTrx, addrssMatch, bfTransSummToUpdate)
            Catch Exception e 
                Log exception details

        End If

        apiTrx.Qual_Results = addrssMatch 
        Validate API Response JSON and handle length restrictions

        If apiTrx.API_Name equals 'ReserveAppointment' then
            updateAppointmentReference(bfTransSummToUpdate, apiTrx, inputMap)

        If apiTrx.API_Name equals 'retrieveAppointment' then
            updateTransactionStatus(apiTrx, transaction_record)

    End For

    Prepare TransactionWrapper for return
    wrap.apiTransactionList = apiTransactionList
    If bfTransSummToUpdate is not empty then 
        wrap.bfTransSummToUpdate = values of bfTransSummToUpdate

    Return wrap
End Function
Helper Functions


Update Company Owner


Function updateCompanyOwner(bfTransSummToUpdate, apiTrx)
    Retrieve summRec = bfTransSummToUpdate.get(apiTrx.Buyflow_Transaction_Summary_ID)
    If summRec is not NULL then
        summRec.CompanyOwnerId = captureCompanyOnwerIdBMFlow(apiTrx.API_Response_JSON)
    Else
        Create new BF_Transactions_Summary entry in bfTransSummToUpdate with company owner ID
    End If
End Function
Update Appointment Reference


Function updateAppointmentReference(bfTransSummToUpdate, apiTrx, inputMap)
    Retrieve summRec = bfTransSummToUpdate.get(apiTrx.Buyflow_Transaction_Summary_ID)
    If summRec is not NULL then
        summRec.Appointment_Order_ID = inputMap['AppointmentReferenceNumber']
    Else
        Create new BF_Transactions_Summary entry in bfTransSummToUpdate with appointment ID
    End If
End Function
Update Transaction Status


Function updateTransactionStatus(apiTrx, transaction_record)
    If transaction_record[0].Source equals 'Martens' AND apiTrx.API_Response_JSON is not blank then
        Deserialize apiTrx.API_Response_JSON into retrieveApptsResp
        For each appt in retrieveApptsResp do
            Check if appointment is available
            If available then
                Set apiTrx.API_Status to 'success'
                Break
            End If
        End For
    End If
End Function
