Hello, still in exploratory stages at the moment. does that team has an example to share the illustrates how, using objectivec, one could http POST both a json package and document to sign using the REST api? i'm trying to achieve the same outcome as the PYTHON script; simply replicate in objectivec. any assistance would be greatly appreciated!! the python script makes it look to easy!
# test1 for creating package
# payload = codecs.open('package.json', 'r',encoding='utf8').read()
# print(payload)
# documents = {'file': open(os.getcwd()+'/newaccount-v1.pdf', 'rb').read()}
# print("creating package")
# print(client.create_package_multipart(payload, documents))
# test1 end
cheers.

Hello rdediana, Sorry for the delay. I had some major computer issues that had me mostly down for a couple weeks and I forgot to make sure this was followed up on. I apologize. You can definitely use templates within eSignLive to house the documents and use the REST API to provide an update to the package JSON. I have gotten the following sample from our mobile team where it looks like they're showing how to do the entire multipart form in objective C vs using a template. I also have a sample application I can load into our code share, if you think that would be helpful. If this isn't what you're looking for, let me know. :) Sorry again for the delay.
NSString *payload = @"{\"status\": \"DRAFT\",\"roles\": [{\"id\": \"signer1\",\"signers\": [{\"email\": \"[email protected]\",\"firstName\": \"Qamar\",\"lastName\": \"Suleiman\"}]}],\"documents\": [{\"description\": \"this is description\",\"approvals\": [{\"role\": \"signer1\",\"fields\": [{\"type\":\"SIGNATURE\",\"subtype\": \"FULLNAME\",\"page\": 0,\"top\": 100,\"left\": 100,\"width\": 200,\"height\": 60}]}],\"name\": \"Document1\"}],\"name\": \"TransactionTest\"}";

Trying to get someone with objectivec experience to help with this. What have you tried so far that is not working?

hey Team, Any way to identify the issue behind this message;
2016-06-18 17:11:04.533 ESLRemoteExpert[82361:18662663] {"messageKey":"error.internal.default","technical":"65533","message":"Unexpected Error.

potentially viewing the server logs?

Have you tried a more basic call? Like just changing the status of a SENT package to DRAFT? Just want to make sure you can successfully make a call to ESL with the REST API from your objective c code. I would guess the problem is an issue with the JSON payload. Unfortunately, I don't have an objectivec test environment on my Windows machine. I will look into an objective c IDE/compiler for Windows to see if I can actually test this out, myself.

Hello Michael, just tried the bellow request, which completed successfully.

    request.HTTPMethod = @"GET";
    [request setValue:@"Basic enVyZ1A3Y...................94b0U4Tw==" forHTTPHeaderField: @"Authorization"];
    // 3
    
    NSError *error = nil;
    
    if (!error) {

curious. to simply the requirements, can i host the documents in a template within ESL and reference this template when creating a new package. ? i could still submit JSON data for role and package attributes, and simply reference pre-positioned documents hosting on the ESL server / cloud? if yes, could you provide some guidance on how to create a new package, which submits the role / package details via JSON REST API, while referencing the template for document requirements. . thanks for any assistance. regards,
