I need to get this id “4FR34FR34FR34FR3A” to capture payment, how can I can I get this id from this response in golang?

Your response is in JSON format. Unmarshal it.

3

Use https://mholt.github.io/json-to-go/ to convert your json string to a go struct

4

really useful. Great

I am working with Rest Api, using decoded json data. We can achieve this without Unmarshal, using range loop.
for i, transactionRes := range paymentResponse.Transactions {
obj := transactionRes.RelatedResources[i]
id := obj.Authorization.ID
returnData[“paypal_auth_id”] = id

}

I don’t think that is a good idea because your code become unmaintainable. Some should work hard to understand what the loops does, instead of looking over a well organised struct.
