REST API and Basic Authentication, requirements.

What are the requirements to execute REST API calls?

All Supported Releases.

All REST Call Services Into the instance can use Basic Authentication. 

Basic Authentication is equivalent to have a local username and password to authenticate to when the REST call is executed. This user is stored locally in sys_user table.

Alternatively, you may use Oauth token authentication for REST Calls into the platform.


For most ServiceNow REST APIs these request headers support the following values:
→ Accept: application/json, application/xml
→ Content-Type: application/json, application/xml

For the list of specific values supported by each endpoint, refer to the REST API reference.
