Expose a POST endpoint which accepts an input JSON object with payload, referenceData and returns a transformedPayload (JSON). The POST API should substitute the {REF_*} values in payload using refernceData and return the transformed payload. Upper limit for the payload size is 10MB. Input payload to POST API { "payload": { "name": "subscriber", "valueType": "array", "value": [ { "name": "MN", "valueType": "string", "value": "{REF_MSISDN}" }, { "name": "IM", "valueType": "string", "value": "{REF_IMSI}" }, { "name": "NT", "valueType": "string", "value": "G" }, { "name": "privateUser", "valueType": "array", "value": [ { "name": "privateUserId", "valueType": "string", "value": "{REF_IMSI}@ims.mnc001.mcc505.3gppnetwork.org" }, { "name": "roamingAllowed", "valueType": "string", "value": "false" }, { "name": "publicUser", "valueType": "array", "value": [ { "name": "publicIdValue", "valueType": "string", "value": "sip:{REF_IMSI}@ims.mnc001.mcc505.3gppnetwork.org" }, { "name": "implicitRegSet", "valueType": "string", "value": "1" }, { "name": "serviceProfileId", "valueType": "string", "value": "{REF_SERVPROFID}" }, { "name": "testUser", "valueType": "array", "value": [ { "name": "testIdValue", "valueType": "string", "value": "sip:{REF_IMSI}@ims.mod-connect.com" }, { "name": "implicitRegSet", "valueType": "string", "value": "2" } ] } ] }, { "name": "userImsi", "valueType": "string", "value": "{REF_IMSI}" } ] }, { "name": "PO", "valueType": "string", "value": "0" } ] }, "referenceData": { "REF_MSISDN": "0406679321", "REF_IMSI": "50002312344314", "REF_SERVPROFID": "2" } } Expected API Response { "name": "subscriber", "valueType": "array", "value": [ { "name": "MN", "valueType": "string", "value": "0406679321" }, { "name": "IM", "valueType": "string", "value": "50002312344314" }, { "name": "NT", "valueType": "string", "value": "G" }, { "name": "privateUser", "valueType": "array", "value": [ { "name": "privateUserId", "valueType": "string", "value": "50002312344314@ims.mnc001.mcc505.3gppnetwork.org" }, { "name": "roamingAllowed", "valueType": "string", "value": "false" }, { "name": "publicUser", "valueType": "array", "value": [ { "name": "publicIdValue", "valueType": "string", "value": "sip:50002312344314@ims.mnc001.mcc505.3gppnetwork.org" }, { "name": "implicitRegSet", "valueType": "string", "value": "1" }, { "name": "serviceProfileId", "valueType": "string", "value": "2" }, { "name": "testUser", "valueType": "array", "value": [ { "name": "testIdValue", "valueType": "string", "value": "sip:50002312344314@ims.mod-connect.com" }, { "name": "implicitRegSet", "valueType": "string", "value": "2" } ] } ] }, { "name": "userImsi", "valueType": "string", "value": "50002312344314" } ] }, { "name": "PO", "valueType": "string", "value": "0" } ] }
