How to: Implement Custom Code in Dispatch Service

6min

Implementing Pre-Configured Custom Code
The pre-configured Custom Code URL is available for each API that supports Custom Code. The Custom Code will be registered and configured for a type - Like handlers﻿.
Developers can configure the Custom Code for - Create Instance, Update Instance, and Apply Event.
Implementing Custom Code in the Request Body
To dynamically modify the Custom Code config for each API call, we've added two attributes﻿﻿.﻿
It can be used for creating, updating, and applying requests.
﻿
Custom Code Fields
To add custom code in the Dispatch service﻿ add the following values in the request body:
Name

wait
boolean

acceptableStatusCodes
array
Acceptable status codes.
raiseErrorOnStatusMismatch
boolean
Raise an error if the status code returned doesn’t match acceptableStatusCodes.
methodName**

📘 methodNames allowed are - createDispatch:onRequest, updateDispatch:onRequest, updateDispatchStatus:onRequest, updateDispatchSubStatus:onRequest, addParticipant:onRequest, removeParticipant:onRequest, addParticipantBulk:onRequest, addJob:onRequest, removeJob:onRequest, removeMultipleJobs:onRequest, removeJobFromDispatch:onRequest, removeMultipleJobsFromDispatch:onRequest, addJobByRef:onRequest, changeStatusByRef:onRequest, changeSubStatusByRef:onRequest, addMultipleJobsByRef:onRequest, removeMultipleJobsByRef:onRequest, removeJobByRef:onRequest, addParticipantByRef:onRequest, addMultipleParticipantsByRef:onRequest, removeParticipantByRef:onRequest, updateCustomDataByRef:onRequest, patchCustomDataByRef:onRequest, addJobBulk:onRequest, createJob:onRequest, updateCustomData:onRequest, patchCustomData:onRequest, updateJobStatus:onRequest, updateJobSubStatus:onRequest, custodyIn:onRequest, custodyOut:onRequest, custodyInBatch:onRequest, custodyOutBatch:onRequest, createDispatch:onError, updateDispatch:onError, updateDispatchStatus:onError, updateDispatchSubStatus, addParticipant:onError, removeParticipant:onError, addParticipantBulk:onError, addJob:onError, removeJob:onError, removeMultipleJobs:onError, removeJobFromDispatch:onError, removeMultipleJobsFromDispatch:onError, addJobByRef:onError, changeStatusByRef:onError, changeSubStatusByRef:onError, addMultipleJobsByRef:onError, removeMultipleJobsByRef:onError, removeJobByRef:onError, addParticipantByRef:onError, addMultipleParticipantsByRef:onError, removeParticipantByRef:onError, updateCustomDataByRef:onError, patchCustomDataByRef:onError, addJobBulk:onError, createJob:onError, updateCustomData:onError, patchCustomData:onError, updateJobStatus:onError, updateJobSubStatus:onError, custodyIn:onError, custodyOut:onError, custodyInBatch:onError, custodyOutBatch:onError
Expected Response From Custom Code
Data is expected in response to the Custom Code with the existing payload in the data fields.
JSON
{  
  data: {  
	...  
  }  
}
{  
  data: {  
	...  
  }  
}
﻿
Data Formation from Custom Code Response
The fields returned from Custom Code inside the data field are replaced with the existing payload as shown below.
The Payload in Request Body
JSON
{
    "dispatchType": "PUDO",
    "dispatchRef": "DSP-0001-0001",
    "tenantId": "delhivery",
}
{
    "dispatchType": "PUDO",
    "dispatchRef": "DSP-0001-0001",
    "tenantId": "delhivery",
}
﻿
Payload returned from Custom Code
JSON
{
    "customData": {
         "facilityId": "facility-1",
     }
}

{
    "customData": {
         "facilityId": "facility-1",
     }
}
