Zendesk provides 3 ways of authenticating API requests:

  • OAuth access token
  • API token
  • basic authentication with a username and password

You normally opt for OAuth tokens when you need users to grant your application access to their accounts. This involves building an OAuth authorization flow.

You can also use OAuth tokens for other types of requests that don't require user authorization. For example, you might use them in applications used by internal staff or by the general public. Using OAuth tokens for authentication doesn't tie the requests to a specific username and password, and it offers more control and security than plain API tokens.

The following example is a request that uses an OAuth token for authentication:

curl https://obscura.zendesk.com/api/v2/users.json \  -H "Authorization: Bearer 52d7ef4ee01e2c2c75bff572f957cd4f12d6225eee07ea2f01d01a"

Warning: An OAuth access token is like a password. Keep it secure. If at any time you suspect a token has been compromised, revoke it at once. See Revoke Token.

Creating a token with the Zendesk API

The section describes the steps to create an OAuth access token with the Zendesk API:

  1. Create an OAuth client
  2. Get the client id
  3. Create the access token
  4. Use the access token in requests

You can use basic authentication or an API token to make Zendesk API requests. Don't confuse an API token with an OAuth access token. You can get an API token from the Support admin interface. See Using a Zendesk API token in the Support API docs.

If your organization uses single sign-on (SSO) and the Zendesk passwords were deleted from the Zendesk account, you'll have to use an API token to make the requests.

Create an OAuth client

  1. In Admin Center, click the Apps and integrations icon () in the sidebar, then select APIs > Zendesk API > OAuth Clients.
  2. Complete the form. See Registering your application with Zendesk for details.

Get the client id

Use the List Clients endpoint to get the id of your new client.


Basic authentication

curl https://{subdomain}.zendesk.com/api/v2/oauth/clients.json \  -v -u {email_address}:{password}

API token

curl https://{subdomain}.zendesk.com/api/v2/oauth/clients.json \  -v -u {email_address}/token:{api_token}


{"clients":  [    {      "name": "OAuth client for my app",      "id": 50328,      "user_id": 293241756,      ...    },    ...  ]}

Create the access token

Use the client id in the Create Token endpoint to get an access token.

The endpoint can only be used by Support admins.

Note: If the admin's role is later changed to agent or end user, then the token's access permissions will also be changed to that of the new role. For example, it will no longer work with endpoints that are only allowed for admins.


Basic authentication

curl https://{subdomain}.zendesk.com/api/v2/oauth/tokens.json \  -d '{"token": {"client_id": "50328", "scopes": ["read", "write"]}}' \  -H "Content-Type: application/json" \  -X POST -v -u {email_address}:{password}

API token

curl https://{subdomain}.zendesk.com/api/v2/oauth/tokens.json \  -d '{"token": {"client_id": "50328", "scopes": ["read", "write"]}}' \  -H "Content-Type: application/json" \  -X POST -v -u {email_address}/token:{api_token}

Learn more about scopes in Setting the scope in the Zendesk Support Help Center.


{"token":  {    "full_token":"52d7ef4ee01e2c2c75bff572f957cd4f12d6225eee07ea2f01d01a",    "scopes":["read","write"],    ...  }}

The full_token property specifies the access token. Keep the value in a safe place.

Use the access token in requests

Use the access token in an Authorization header in your requests. Example:

curl https://{subdomain}.zendesk.com/api/v2/users.json \  -H "Authorization: Bearer 52d7ef4ee01e2c2c75bff572f957cd4f12d6225eee07ea2f01d01a"

In curl, the -H flag indicates a header field.
