Server Side

Save the below assigned value at your server

String apiEndPoint = "/v3/profile"; // Discuss with PhonePe team regarding this

Construct the request body and encode in Base 64 as follows:

HashMap<String, Object> data = new HashMap<>();
data.put("merchantId", <Your merchant ID>); // Mandatory
data.put("transactionId", <Unique transaction id>); // Mandatory
data.put("merchantUserId", userId); // Mandatory. Needed for linking
 
data.put("mobileNumber", <Mobile number of the user>); // Optional
data.put("email", <Email of the user>); // Optional
data.put("shortName", <Name of the user>); // Optional
 
// Put more info as intimated. Nesting is allowed
 
String base64Body = Base64(new GSON().toJson(data));

Select one of the salts shared with you and note its index. Construct Checksum as follows:

String checksum = sha256(base64Body + apiEndPoint + salt) + ### + saltIndex;

App Side

Collect Base64 encoded body, checksum, apiEndPoint and transactionID from your server using an API call.
Initiate the process to show profile as follows:

let profileRequest = PPSTransactionRequest(
    base64EncodedBody: <#body received by your server#>,     
    apiEndPoint: <#apiEndPoint received by your server#>,
    checksum: <#checksum received by your server#>)
 
PhonePeSDK.shared().startPhonePeTransactionRequest(profileRequest,
    on: self, animated: true) { 
    (request, result) in 
    //Do something with the request/result
}
//If you get any error, refer to the iOS Merchant Integration Document section troubleshoot for the steps to debug.

PPSTransactionRequest * profileRequest = [[PPSTransactionRequest alloc]   
    initWithBase64EncodedBody:<#body received by your server#>
    apiEndPoint:<#apiEndPoint received by your server#>
    checksum:<#checksum received by your server#>];
 
[[PhonePeSDK shared] startPhonePeTransactionRequest:profileRequest
                     onViewController:self animated:YES
                     completion:^(PPSTransactionRequest * request, PPSTransactionCompletionResult * result) {
//Do something with request/result
}];
//If you get any error, refer to the iOS Merchant Integration Document section troubleshoot for the steps to debug.
