---title: What is a SID?description: Learn about a SignalWire ID below!slug: /guides/what-is-a-sidsidebar_position: 4x-custom: ported_from_readme: true---What is a SID?--------------A SID is a SignalWire ID that is used as a security identifier. It is a universally unique alphanumeric string that is generated for **all** various types of communication aspects that our platform offers. Projects, calls, SMS, recordings, faxes, LAML bins, and nearly **all** SignalWire components will all be labeled with a unique SID that can be used in our API or for logging/tracking purposes. When filing a support ticket, you should **always** include the SID of whatever test is taking place. If messages or calls are failing, providing the SID of a failed message is the fastest way to allow the SignalWire Support team to isolate the technical issue.Where can I find a SID?-----------------------**Great** question! You can find the SID within your SignalWire space, or you can see it returned from the API when you make an API call. We will go over some of the different SIDs you might need below. JSON Response-------------When you make an API call, you will see a JSON response returned from SignalWire that contains information about the request you just made. For example, if you sent a message using the API, you might see this returned! text JSON{ account_sid: ea108133-d6b3-407c-9536-9fad8a929a6a, api_version: 2010-04-01, body: Hello World, num_segments: 1, num_media: 0, date_created: Mon, 13 Aug 2018 23:08:35 +0000, date_sent: null, date_updated: Mon, 13 Aug 2018 23:08:35 +0000, direction: outbound-api, error_code: null, error_message: null, from: +15551234567, price: null, price_unit: USD, sid: b3877c40-da60-4998-90ad-b792e98472af, status: queued, to: +15557654321, messaging_service_sid: null, uri: /api/laml/2010-04-01/Accounts/ea108133-d6b3-407c-9536-9fad8a929a6a/Messages/b3877c40-da60-4998-90ad-b792e98472af, subresource_uris: { media: /api/laml/2010-04-01/Accounts/ea108133-d6b3-407c-9536-9fad8a929a6a/Messages/b3877c40-da60-4998-90ad-b792e98472af/Media }}Here you can see 2 SIDs, the message SID referred to as sid that identifies the individual message you just sent, and account_sid which refers to your project ID! If you want to keep track of your usage programmatically, making use of the JSON responses returned in conjunction with our APIs is the best way to do so. :::info Important Note about your Account SID/Project IDThe API documentation requires that you use your **Account SID**. This actually refers to your **Project ID**! We kept the Account Sid terminology consistent with other popular providers to make transitioning your existing applications to SignalWire a breeze! Your project ID can be found on the dashboard within your individual project, or within the API tab.:::You can find your Project ID, Authorization Token, and Space URL all in one convenient spot in your portal! These three variables are needed to make ANY API call. Click the **API** tab in your lefthand side navigator to see all three variables in an easily copyable format!
