Search for an address

Learn how to access the geocoding service.

Search for an address using API key authentication

Geocoding is the process of converting address or place text into a location. The Geocoding service can search for an address or a place and can also perform reverse geocoding.

In this tutorial, you find the location of an address.

Prerequisites

An ArcGIS Location Platform or ArcGIS Online account.

Steps

Get the starter app

Select a type of authentication below and follow the steps to create a new application.

If you are using the CDN libraries, to get started.

Set up authentication

Create developer credentials in your portal for the type of authentication you selected.

Create a new API key credential with the correct privileges to access the resources used in this tutorial.

Go to the Create an API key tutorial and create an API key with the following privilege(s):
- Privileges:
  - Location services > Geocoding
Copy the API key access token to your clipboard when prompted.

Set developer credentials

Use the API key or OAuth developer credentials so your application can access location services.

Update the accessToken variable to use your API key.

Use dark colors for code blocks
    const accessToken = "YOUR_ACCESS_TOKEN";

In both the index.html and callback.html files, replace YOUR_CLIENT_ID and YOUR_REDIRECT_URL with the client ID and redirect URL of your OAuth credentials.

index.html
Use dark colors for code blocks
    const authentication = await arcgisRest.ArcGISIdentityManager.beginOAuth2({
       clientId: "YOUR_CLIENT_ID", // Your client ID from OAuth credentials
       redirectUri: "YOUR_REDIRECT_URL", // The redirect URL registered in your OAuth credentials
       portal: "https://www.arcgis.com/sharing/rest" // Your portal URL
    })

callback.html
Use dark colors for code blocks
    arcgisRest.ArcGISIdentityManager.completeOAuth2({
      clientId: "YOUR_CLIENT_ID", // Your client ID from OAuth credentials
      redirectUri: "YOUR_REDIRECT_URL", // The redirect URL registered in your OAuth credentials
      portal: "https://www.arcgis.com/sharing/rest" // Your portal URL
    })

Run the app and ensure you can sign in successfully.

If you are unable to sign in, make sure you have the correct redirect URL and port. This URL varies based on your application and typically takes the format of https://<server>[:port]/callback.html or http://my-arcgis-app:/auth. For example, if you are running an application on http://127.0.0.1:5500/, set http://127.0.0.1:5500/callback.html as your redirect URL in the index.html and callback.html file and your developer credential. They all have to match!

Make the request

Copy and paste the code below, following the steps to make a request to the Geocoding service.

Reference the arcgis-rest-request and arcgis-rest-geocoding libraries either through CDN, ES Modules, or Node JS.
Define the parameters needed for the request.
Call the Geocoding service and handle the results.
