Discovery can find devices that use the HTTP protocol.
Note:  
For information on Probe to Pattern migration see the knowledge article [KB0694477](https://support.servicenow.com/kb_view.do?sysparm_article=KB0694477).

## Classifier, probes, and patterns {#http-discovery__section_dy1_hvv_bdb}

HTTP discovery relies on a the HTTP port probe, which Discovery runs
after trying to run SSH and SNMP port probes. This port probe launches the HTTP - Classify probe which runs an HTTP GET request for every entry in the HTTP
classification table. You should configure your own classifications that the HTTP - Classify probe can access.

The HTTP port probe uses mappings between a protocol and port number in the IP Service
\[cmdb_ip_service\] table. You can add additional port-to-protocol definitions in this table, or
you can override the protocol used for a specific HTTP classifier.

* **[Run discovery through an HTTP or HTTPS REST call](https://servicenow-prod.fluidtopics.net/SMHrp0tU1OoXVoeSHfrIDQ)**   
  Discovery can classify devices using the HTTP(S) protocol. You can create your own HTTP classifier to find devices and access them with Basic Auth credentials, rather than using SNMP or SSH credentials.
