Integration with Odisha IFMS (Integrated Financial Management System) is via the Just-in-Time (JIT) APIs provided by the Odisha treasury.
The following pieces of information are shared offline:
clientId
clientSecret
publicKey from JIT systems
Head of accounts to be used for the Mukta scheme at the state level - to be provided by HUDD
Spending unit details specific to each ULB are to be provided by HUDD.
expense service
expense-calculator service
bank-account service
individual service
organisation service
audit-log service
IDGen service
MDMS service
encryption service
IFMS adapter manages funds summary based on the head of accounts and SSU codes. It creates sanctions for each head of accounts and SSU details based on ULB tenant ID.
There are three types of transactions that can be received from the JIT VA API -
Initial Allotment - A new sanction will be created only if AllotmentTxnType is Initial Allotment.
Additional allotment - For this type of transaction it will update the amount of existing sanction.
Allotment withdrawal - It deducts the transaction amount from the sanction for this type of transaction.
When a bill is approved this service creates payment using the expense service.
There are consumers who keep listening to the payment create Kafka topic and generate payment instructions (PI) using payment and bill details and post the PI to the IFMS system using JIT API.
A new PI will be generated when enough funds are available for any head of accounts for that tenantId.
Before posting the PI there were multiple enrichments like bankaccount details, org and individual details, etc.
After creating the PI it deducts the available balance from the funds summary.
If a PI is created for any payment then the user can not generate a PI again till the PI fails.
It keeps a log of each status call of PI and saves it in the DB
IFMS adapter connects JIT with two APIs -
authentication - webservices/jitfs/v1.0/authenticate
service request - webservices/jitfs/v1.0/get-jit-service-data
There are multiple cronjobs for the IFMS adapter, all jobs are built using a single codebase with multiple charts, these charts are required to configure cronjobs with multiple configurations.
All cronjobs uses ifms/scheduler?serviceId={SERVICE_ID} API, the business logic is defined for each service code.
Service codes are -
ifms-cronjob-pa
PA
It is used to create payment for approved bills, uses expense service API
ifms-cronjob-va
VA
It fetches the allotment details using JIT API's.
ifms-cronjob-pis
PIS
After PI creation it fetches whether the payment instruction's sanction is generated or not.
ifms-cronjob-pag
PAG
After receiving the PIS response it fetches for payment advice generation using JIT API.
ifms-cronjob-pd
PD
After receiving the PAG response it keeps fetching data for the PD service JIT API. The response will be received when payment is processed.
ifms-cronjob-fd
FD
It uses JITs bulk failure API and returns failed payments of the last 72hrs.
ifms-cronjob-ftps
FTPS
This same as PD - it is used for the revised transaction.
ifms-cronjob-ftfps
FTFPS
After receiving the response from FTPS API it keeps fetching data of failedrequests transactions of revised transactions.
All requests and responses are logged in an encrypted fashion in two indexes in ES.
ifms-request-logs
ifms-error-logs
Each request that is sent to JIT will be logged in the ifms-request-logs index. The index name is configurable in application.properties, Helm chart and environment file. There are multiple fields for the request:
id - uuid of the request
serviceId - Contains service ID of jit request like VA, PI, PIS etc
jitBillNo - Contains bill number for which it’s calling the JIT API, it’s applicable for PI, PIS, PAG, PD, FTPS, and FTFPS. Note: For Auth request jitBillNo will be AUTH
encRequest - Contains request body which is encrypted using ifms.request.enc.secret value. You can decrypt this using the same secret.
decryptionRek - Contains decryption rek which helps to decrypt the JIT response received from JIT.
encResponse - Response received from JIT.
createdtime - The time when the request was sent to the JIT system
When the user sends any request to JIT and gets an error response, then it will store the details in ifms-error-logs index. It has multiple fields
serviceId - Contains service ID of jit request like VA, PI, PIS etc
requestId - This is uuid of ifms-request-logs index
statusCode - Status code of Network response
jitEncRequest - Encrypted request which is sent to the JIT, we can not decrypt this request.
errorMsg - Error response which was received from JIT
encryptionRek - Encryption rek using which request is encrypted
decryptionRek - Contains decryption rek which helps to decrypt the JIT response
authToken - Auth token which request was sent to the JIT
sekString - sek which was received from the login
createdtime - The time when the request was sent to the JIT system
All other master data is configured inside the folder at a state level as well as a folder inside a ULB level.
