SCIM-SAML-Identities.graphql

# Pass the URL for an Organization into the query
# to get a list of members in a specific Organization.
# Example: { "url": "https://github.com/:organization" }
query getResource($url: URI!) {
  resource(url: $url) {
    ... on Organization {
      samlIdentityProvider {
        externalIdentities(first:10) {
          nodes {
            scimIdentity {
              username
            }
            samlIdentity {
              nameId
            }
            user {
              login
              email
            }
          }
        }
      }
    }
  }
}

this example needs admin:org, user:email and user:read scope + the OAuth/PAT has to be authorized for use in the SAML protected organization

Also if you need pagination, you'll want something like below:

query getResource($url: URI!) {
  resource(url: $url) {
    ... on Organization {
      samlIdentityProvider {
        externalIdentities(first:100, after:"xxxxxxxxx") {
            nodes {
              scimIdentity {
                username
              }
              samlIdentity {
                nameId
              }
              user {
                login
                email
              }
            }
          edges{
            node {
              user {
                login
              }
            }
          }
          pageInfo {
            endCursor
            hasNextPage
          }
        }
      }
    }
  }
}
