How to validate form based on integration result

You have multiple options. The straight forward one is to add another user input task to your process model and add a XOR in the path checking the result of the integration. If the integration fails, go to the new task. Make sure to enable chaining on all connectors between the first task and the new one. The new added task can show that error message to the user.

Depending on your needs you can allow the user to modify the data and retry.

Hi Suresh,

If you want to call and validate the service response at Submit button and you don't want to proceed to next interface in case of failure, i think we need to put validation rules so that when service has failed it should not allow form to be submitted.

You could try to implement below logic, to stop form being submitted in case of service failure:

a!localVariables(
local!success: {},
{
a!sectionLayout(
contents: {
a!textField(
label: "Service Input",
value: ri!integrationInput,
saveInto: ri!integrationInput,
validations: if(
local!success,
{},
"Service Failure Message"
)
),

},

),
a!buttonArrayLayout(
buttons: {a!buttonWidget(
label: "Submit",
style: "PRIMARY",
saveInto: {
a!save(
local!success,
rule!integrationCall(
ri!integrationInput
).success
)
},
submit: true,
validate: true
)}
)}
) 

It did not work.

since local!success is not true initially, on button click validation is applied on textField and validation message will be displayed before calling the rule!integrationCall() and local!success will never become true.

I do not recommend to go that way. You would need to implement some complex logic for saveInto and validations to catch all cases. Try to go the process route.
