Service Now Fluent API

Easy to connect, and interact with Service Now API

📕 See the Full Documentation


Make request using fluent API!

  • 🧰 Easy to use, based on the config file it connects and authenticate without one line of code
  • 🔑 Typed data, you can use properties to manipulate and restrict requests
  • 🛠 Typed properties can be used in Selects, Queries, Ordering...
  • 🧩 Auto serialize/deserialize included
  • 🎲 Generic Json Elements available as responses
  • 📑 Methods and classes have documentation comments, get feedback as you type
  • 🗜 Compress requests by default
  • 👓 Extensions methods to change and get data from generic responses, log and much more...


  • .Net Core 3.1
  • .Net Framework 4.6.1


  • Install the package.
  • Set an appsettings.json with correct connection values.
    • The library check if scope has and .default or not to define how it will get access tokens
    • You can use Credentials or Client Secrets for daemon applications
  • Create an instance of ServiceNow.
  • Create an instance of a Table, (typed or not).
  • Configure the request as you like.
  • make the request with ToListAsync.

Basic Examples

  • Typed (Create any class derived from ServiceNowBaseModel class, so we have an Id Guid)
//Creating an ServiceNow instance
var ServiceNow = new ServiceNow(config);

//Creating an table instance
var usersTable = ServiceNow
    .WithQuery(x => $"{x.Name} like Branco and {x.Country} = BR");

//Getting data
var users = await usersTable.ToListAsync();

while (users.Count > 0)
    foreach (var user in users)
    //Next Request will get the next chunk of data
    users = await usersTable.ToListAsync();

Same as above but using Where

//Creating an table instance
var usersTable = ServiceNow
    .Where(x => x.Name.Contains("Branco") && x.Country = "BR");
  • Not typed
var usersTableNotTyped = ServiceNow
    .WithQuery("name like Branco and country = BR");
var usersNotTyped = await usersTableNotTyped.ToListAsync();

while (usersNotTyped.Count > 0)
    usersNotTyped.ForEach(userNotTyped => userNotTyped.Display());
    usersNotTyped = await usersTableNotTyped.ToListAsync();
  • Changing not typed Data
//Creating a table instance
var incidentsTableNotTyped = ServiceNow

//Getting data
var incidentsNotTyped = await incidentsTableNotTyped
        .Select(new[] { "sys_id", "short_description" })
        .WithQuery("short_description like some nice")

incidentsNotTyped.ForEach(async incident =>
    Guid id = new Guid(incident.GetProperty("sys_id").ToString());
    ExpandoObject inc = incident.ToObject();
    inc.UpdateProp("short_description", "changed description on non typed value");
    var changed = await incidentsTableNotTyped.Update(id, inc);
    if (changed)
        Console.WriteLine("Incident Changed");
        Console.WriteLine("Incident NOT Changed");

You can create CatalogItem

See Service Now Docs to learn more

  • You must first create an application in studio inside ServiceNow and then:
    • Create a catalogItem
    • create a flow
var requestCatalog = serviceNow.UsingCatalog<Request>(new Guid("catalogItemIdHere"));

var request = await requestCatalog.Request(new{
    varNameHereString = "string",
    varNameHereNumber = 10,
    varNameHereReference = new Guid(sys_id),
}); ;

You can set custom Serializers (You must set it only once, this is optional)

 //AddCustom Custom Serializers to static class used in ServiceNow
JsonConverterOptions.ConfigureCustomSerializers(new[] {
    new CustomRequestStateConverter() 

Default Serializers for Guid and DateTime and DateOnly

When there is no value in the json response (while using not nullable version) it will return:

  • new DateTime() "{1/1/0001 12:00:00 AM}"
  • Guid.Empty

That happens because ServiceNow not always return null, in those cases it returns an empty string.


  • You can open issues to help improve and collaborate with the library.
  • Demos included in project (only the console version for now)
