Fill in Label Field after Transaction Created from Template

Hi Richard,

Thanks for your post!

I would suggest to use this API (PUT /api/packages/{packageId}/documents/{documentId}/approvals/) to update all the fields under one signature in bulk. Below is some code snippets in Java SDK which is very similar to .Net code: 

        //create a package out of the template
        PackageId templatePackageID = new PackageId("GbstM-DP5mB7hC0xdDZ2wvc1uW4=");

        DocumentPackage newPackage = PackageBuilder.newPackageNamed("Transaction created out of a Template")
            .describedAs("Test Form")
            .withSigner(SignerBuilder.newSignerWithEmail("[email protected]")
                    .withFirstName("firstName")
                    .withLastName("lastName")
                    .withCustomId("Placeholder1")
                    )
            .withSettings(DocumentPackageSettingsBuilder.newDocumentPackageSettings().withInPerson())
            .build();
        
        PackageId pkgId = eslClient.createPackageFromTemplate(templatePackageID, newPackage);
        
        //inject field
        HashMap<String, String> fieldValues = new HashMap<String, String>(){{
            put("FirstName", "John");
            put("LastName", "Smith");
        }};
        DocumentPackage createdPackage = eslClient.getPackage(pkgId);
        Document document = createdPackage.getDocument("AddressForm");
        
        for (Signature signature : document.getSignatures()) {
            boolean isUpdate = false;
            for(Field field : signature.getFields()) {
                if(fieldValues.containsKey(field.getName())) {
                    field.setValue(fieldValues.get(field.getName()));
                    isUpdate = true;
                }
            }
            if(isUpdate) {
                eslClient.getApprovalService().modifySignature(createdPackage, document.getId().getId(), signature);
            }
        }
        
        //send package
        eslClient.sendPackage(pkgId);

The same logic can be applied to Restful API code as well. Please let me know if this works for you and if you need to me create some other sample codes.
